  • Multiple test Active Directory envirovments hand in hand with production domain controllers

    - by MadBoy
    What's the best approach of having multiple test environments next to production one? We have multiple programming teams that build solutions that use Active Directory very often. We have tried different approaches, starting with their own domain controllers (in same subnet), or additional OU's in our production AD that the team gets control over and can create/delete accounts within that one OU. We thought of possible 4 solutions: Setting up separate OU's in ou production env. Creating subdomains for our contoso.com domain like test.contoso.com, something.contoso.com and delegating control to the teams (would we need additional DC's or the two that we have already would be enough to hold this? Setting up additional test domain controler that has a trust to our main domain and all teams can use the test domain controler as they please. Setting up single domain controller for every team/project. We're taking in consideration amount of resources needed, security (for example having multiple domain controlers with multiple passwords may lead users to use simpler passwords) and overall best practices for this scenario.

  • Merge executables to avoid multiple UAC

    - by petebob796
    Is there a program that can merge multiple windows executables into one that can run concurrently or in a sequence. I realize this sounds like how virus's often work but I have real needs. I am trying to avoid multiple UAC prompts in an installation process that runs up multiple MS hot fixes. Any other advice on ways to avoid the UAC prompts when multple exe's are to be installed is appreciated.

  • Tool to run same key strokes on multiple unix machines

    - by virtualvoid
    I want to run the same commands on multiple machines, I know I can do this using ssh scripting or things like clusterssh, however I don't want to install anything on the server. (Don't have the rights) What I want is to just clone the keystrokes across multiple machines e.g. run cat /etc/oratab on one window and same is run on multiple windows e.g. in putty, is there a tool to do that from a windows client.

  • Need to configure multiple default gateways for four seperate physical network ports for a FreeBSD Webserver

    - by user20010
    I need to configure default gateways for four separate physical network interfaces for a FreeBSD Webserver. Basically, this is a web server that needs to be accessed by multiple WANS. I've been using various online resources, and a combination of setfib, pf, and ipfw. This web server will be deployed in multiple sites where access to next hop router info is not available, so we can't use static routes. We've used setfib to successfully create multiple routing tables and can ping beyond every default gateway we've created. Using setfib # ping ip.addr.what.ever we can ping anything available on a wan and beyond the router. The problem is we can't get Apache web server (port 80) traffic to route out when external users access the server(box). Multiple people have examples of binding setfib to ipfw commands, but none of them seem to work.

  • Entity Framework - Single EMDX Mapping Multiple Database

    - by michaelalisonalviar
    Because of my recent craze on Entity Framework thanks to Sir Humprey, I have continuously searched the Internet for tutorials on how to apply it to our current system. So I've come to learn that with EF, I can eliminate the numerous coding of methods/functions for CRUD operations, my overly used assigning of connection strings, Data Adapters or Data Readers as Entity Framework will map my desired database and will do its magic to create entities for each table I want (using EF Powertool) and does all the methods/functions for my Crud Operations. But as I begin applying it to a new project I was assigned to, I realized our current server is designed to contain each similar entities in different databases. For example Our lookup tables are stored in LookupDb, Accounting-related tables are in AccountingDb, Sales-related tables in SalesDb. My dilemma is I have to use an existing table from LookupDB and use it as a look-up for my new table. Then I have found Miss Rachel's Blog (here)Thank You Miss Rachel!  which enables me to let EF think that my TableLookup1 is in the AccountingDB using the following steps. Im on VS 2010, I am using C# , Using Entity Framework 5, SQL Server 2008 as our DB ServerStep 1:Creating A SQL Synonym. If you want a more detailed discussion on synonyms, this was what i have read -> (link here). To simply put it, A synonym enabled me to simplify my query for the Look-up table when I'm using the AccountingDB fromSELECT [columns] FROM LookupDB.dbo.TableLookup1toSELECT [columns] FROM TableLookup1Syntax: CREATE SYNONYM  TableLookup1(1) FOR LookupDB.dbo.TableLookup1 (2)1. What you want to call the table on your other DB2. DataBaseName.schema.TableNameStep 2: We will now follow Miss Rachel's steps. you can either visit the link on the original topic I posted earlier or just follow the step I made.1. I created a Visual Basic Solution that will contain the 4 projects needed to complete the merging2. First project will contain the edmx file pointing to the AccountingDB3. Second project will contain the edmx file pointing to the LookupDB4. Third Project will will be our repository of the merged edmx file. Create an edmx file pointing To AccountingDB as this the database that we created the Synonym on.Reminder: Aside from using the same name for the Entities, please make sure that you have the same Model Namespace for all your Entities  5. Fourth project that will contain the beautiful EDMX merger that Miss Rachel created that will free you from Hard coding of the merge/recoding the Edmx File of the third project everytime a change is done on either one of the first two projects' Edmx File.6. Run the solution, but make sure that on the solutions properties Single startup project is selected and the project containing the EDMX merger is selected.7. After running the solution, double click on the EDMX file of the 3rd project and set Lazy Loading Enabled = False. This will let you use the tables/entities that you see in that EDMX File.8. Feel free to do your CRUD Operations.I don't know if EF 5 already has a feature to support synonyms as I am still a newbie on that aspect but I have seen a linked where there are supposed suggestions on Entity Framework upgrades and one is the "Support for multiple databases"  So that's it! Thanks for reading!

  • InstallUtil Publishing WMI Schema to 64 Bit Directory Instead of 32 Bit Directory

    - by Nick
    This is similar to this question, but it doesn't look like a good solution was ever determined, so I'm opening a new one with clarified details. We wrote a .NET service, which among other things, publishes some of the class hierarchy using WMI. On a 64-Bit machine, we are running the 32-bit version of InstallUtil to install the service. It installs successfully, but when the service runs, we receive the following error message when publishing a WMI class using Instrumentation.Publish() DirectoryNotFoundException - (Could not find a part of the path 'C:\Windows\system32\WBEM\Framework\root\MyNamespace\MyService'.) However, this directory does exist in the C:\Windows\syswow64 directory. If we manually copy that directory structure to the system32 directory, then everything works. However, we are looking for automated solution, because we have this packaged up in an MSI which we distribute onto many servers. We have tried running the 64-Bit version of InstallUtil, to see if that would work, however... and this is the really weird part... it gives us an error on install that says Installing WMI Schema: Started An exception occurred during the Install phase. System.IO.DirectoryNotFoundException: Could not find a part of the path 'C:\Windows\system32\WBEM\Framework\root\MyNamespace\MyService.mof'. It looks as if somehow, the WMI installer flipped around. Has anyone else experienced this, or know of a work around?

  • Parsing Lisp S-Expressions with known schema in C#

    - by Drew Noakes
    I'm working with a service that provides data as a Lisp-like S-Expression string. This data is arriving thick and fast, and I want to churn through it as quickly as possible, ideally directly on the byte stream (it's only single-byte characters) without any backtracking. These strings can be quite lengthy and I don't want the GC churn of allocating a string for the whole message. My current implementation uses CoCo/R with a grammar, but it has a few problems. Due to the backtracking, it assigns the whole stream to a string. It's also a bit fiddly for users of my code to change if they have to. I'd rather have a pure C# solution. CoCo/R also does not allow for the reuse of parser/scanner objects, so I have to recreate them for each message. Conceptually the data stream can be thought of as a sequence of S-Expressions: (item 1 apple)(item 2 banana)(item 3 chainsaw) Parsing this sequence would create three objects. The type of each object can be determined by the first value in the list, in the above case "item". The schema/grammar of the incoming stream is well known. Before I start coding I'd like to know if there are libraries out there that do this already. I'm sure I'm not the first person to have this problem.

  • What are the best workarounds for known problems with Hibernate's schema validation of floating poin

    - by Jason Novak
    I have several Java classes with double fields that I am persisting via Hibernate. For example, I have @Entity public class Node ... private double value; When Hibernate's org.hibernate.dialect.Oracle10gDialect creates the DDL for the Node table, it maps the value field to a "double precision" type. create table MDB.Node (... value double precision not null, ... It would appear that in Oracle, "double precision" is an alias for "float". So, when I try to verify the database schema using the org.hibernate.cfg.AnnotationConfiguration.validateSchema() method, Oracle appears to describe the value column as a "float". This causes Hibernate to throw the following Exception org.hibernate.HibernateException: Wrong column type in DBO.ACL_RULE for column value. Found: float, expected: double precision A very similar problem is listed in Hibernate's JIRA database as HHH-1961 (http://opensource.atlassian.com/projects/hibernate/browse/HHH-1961). I'd like to avoid doing anything that will break MySql, Postgres, and Sql Server support so extending the Oracle10gDialect appears to be the most promising of the workarounds mentioned in HHH-1961. But extending a Dialect is something I've never done before and I'm afraid there may be some nasty gotchas. What is the best workaround for this problem that won't break our compatibility with MySql, Postgres, and Sql Server? Thanks for taking the time to look at this!

  • Schema-less design guidelines for Google App Engine Datastore and other NoSQL DBs

    - by jamesaharvey
    Coming from a relational database background, as I'm sure many others are, I'm looking for some solid guidelines for setting up / designing my datastore on Google App Engine. Are there any good rules of thumb people have for setting up these kinds of schema-less data stores? I understand some of the basics such as denormalizing since you can't do joins, but I was wondering what other recommendations people had. The particular simple example I am working with concerns storing searches and their results. For example I have the following 2 models defined in my Google App Engine app using Python: class Search(db.Model): who = db.StringProperty() what = db.StringProperty() where = db.StringProperty() createDate = db.DateTimeProperty(auto_now_add=True) class SearchResult(db.Model): title = db.StringProperty() content = db.StringProperty() who = db.StringProperty() what = db.StringProperty() where = db.StringProperty() createDate = db.DateTimeProperty(auto_now_add=True) I'm duplicating a bunch of properties between the models for the sake of denormalization since I can't join Search and SearchResult together. Does this make sense? Or should I store a search ID in the SearchResult model and effectively 'join' the 2 models in code when I retrieve them from the datastore? Please keep in mind that this is a simple example. Both models will have a lot more properties and the way I'm approaching this right now, I would put any property I put in the Search model in the SearchResult model as well.

  • Copying a subset of data to an empty database with the same schema

    - by user193655
    I would like to export part of a database full of data to an empty database. Both databases has the same schema. I want to maintain referential integrity. To simplify my cases it is like this: MainTable has the following fields: 1) MainID integer PK 2) Description varchar(50) 3) ForeignKey integer FK to MainID of SecondaryTable SecondaryTable has the following fields: 4) MainID integer PK (referenced by (3)) 5) AnotherDescription varchar(50) The goal I'm trying to accomplish is "export all records from MainTable using a WHERE condition", for example all records where MainID < 100. To do it manually I shuold first export all data from SecondaryTable contained in this select: select * from SecondaryTable ST outer join PrimaryTable PT on ST.MainID=PT.MainID then export the needed records from MainTable: select * from MainTable where MainID < 100. This is manual, ok. Of course my case is much much much omre complex, I have 200+ tables, so donig it manually is painful/impossible, I have many cascading FKs. Is there a way to force the copy of main table only "enforcing referntial integrity". so that my query is something like: select * from MainTable where MainID < 100 WITH "COPYING ALL FK sources" In this cases also the field (5) will be copied. ====================================================== Is there a syntax or a tool to do this? Table per table I'd like to insert conditions (like MainID <100 is only for MainTable, but I have also other tables).

  • Understanding Wordpress database schema - querying from 3rd party app

    - by deceze
    Is there an easy way to grab the latest posts out of a Wordpress wp_posts table using a simple SQL query? I have a Wordpress 2.9.2 installation as part of, but separate from, a larger system. It has a customized theme to look like the rest of the site but has otherwise nothing to do with it. I want to display the latest handful of headlines of posts made using Wordpress on a site of that other system. Preferably I do not want to mess around with importing any of the Wordpress library files. Looking at the database structure I can't see an easy, straight-forward query to simply get the latest revision of the latest posts. The post_status can either be "post" or "inherit", the post_type "post" or "revision" and the parent "0" or the id of the original post of a revision. I can't figure out how to reliably filter different revisions of the same post, drafts, attachments and pages out of this mess and just get the latest revision of the latest posts. I'm aware that the database schema is subject to change in subsequent versions of Wordpress, so shouldn't be relied upon, but that's a minor concern, since it's such a minor feature that could easily be fixed. If I understood how that database is supposed to work, that is.

  • Schema for element with Attributes and Child nodes

    - by Matthew
    I am trying to write xsd type schema for an element that has a custom type to include addition attributes to extend a base type. I am running into trouble getting the syntax right. <xs:element name="graphs"> <xs:complexType> <xs:sequence> <xs:element name="graph" minOccurs="1" maxOccurs="unbounded" type="graphType"> <!-- child elements --> </xs:element> </xs:sequence> </xs:complexType> </xs:element> <xs:complexType name="graphType"> <xs:simpleContent> <xs:extension base="xs:string"> <xs:attribute name="title" type="xs:string"/> <xs:attribute name="type" type="xs:string"/> </xs:extension> </xs:simpleContent> </xs:complexType> I thought this would be something very common, but having read many tuts and forums, I cant seem to find an answer that works for me.

  • Sync Your Pidgin Profile Across Multiple PCs with Dropbox

    - by Matthew Guay
    Pidgin is definitely our favorite universal chat client, but adding all of your chat accounts to multiple computers can be frustrating.  Here’s how you can easily transfer your Pidgin settings to other computers and keep them in sync using Dropbox. Getting Started Make sure you have both Pidgin and Dropbox installed on any computers you want to sync.  To sync Pidgin, you need to: Move your Pidgin profile folder on your first computer to Dropbox Create a symbolic link from the new folder in Dropbox to your old profile location Delete the default pidgin profile on your other computer, and create a symbolic link from your Dropbox Pidgin profile to the default Pidgin profile location This sounds difficult, but it’s actually easy if you follow these steps.  Here we already had all of our accounts setup in Pidgin in Windows 7, and then synced this profile with an Ubuntu and a XP computer with fresh Pidgin installs.  Our instructions for each OS are based on this, but just swap the sync order if your main Pidgin install is in XP or Ubuntu. Please Note:  Please make sure Pidgin isn’t running on your computer while you are making the changes! Sync Your Pidgin Profile from Windows 7 Here is Pidgin with our accounts already setup.  Our Pidgin profile has a Gtalk, MSN Messenger, and Facebook Chat account, and lots of log files. Let’s move this profile to Dropbox to keep it synced.  Exit Pidgin, and then enter %appdata% in the address bar in Explorer or press Win+R and enter %appdata%.  Select the .purple folder, which is your Pidgin profiles and settings folder, and press Ctrl+X to cut it. Browse to your Dropbox folder, and press Ctrl+V to paste the .purple folder there. Now we need to create the symbolic link.  Enter  “command” in your Start menu search, right-click on the Command Prompt shortcut, and select “Run as administrator”. We can now use the mklink command to create a symbolic link to the .purple folder.  In Command Prompt, enter the following and substitute username for your own username. mklink /D “C:\Users\username\Documents\My Dropbox\.purple” “C:\Users\username\AppData\Roaming\.purple” And that’s it!  You can open Pidgin now to make sure it still works as before, with your files being synced with Dropbox. Please Note:  These instructions work the same for Windows Vista.  Also, if you are syncing settings from another computer to Windows 7, then delete the .purple folder instead of cutting and pasting it, and reverse the order of the file paths when creating the symbolic link. Add your Pidgin Profile to Ubuntu Our Ubuntu computer had a clean install of Pidgin, so we didn’t need any of the information in its settings.  If you’ve run Pidgin, even without creating an account, you will need to first remove its settings folder.  Open your home folder, and click View, and then “Show Hidden Files” to see your settings folders. Select the .purple folder, and delete it. Now, to create the symbolic link, open Terminal and enter the following, substituting username for your username: ln –s /home/username/Dropbox/.purple /home/username/ Open Pidgin, and you will see all of your accounts that were on your other computer.  No usernames or passwords needed; everything is setup and ready to go.  Even your status is synced; we had our status set to Away in Windows 7, and it automatically came up the same in Ubuntu. Please Note: If your primary Pidgin account is in Ubuntu, then cut your .purple folder and paste it into your Dropbox folder instead.  Then, when creating the symbolic link, reverse the order of the folder paths. Add your Pidgin Profile to Windows XP In XP we also had a clean install of Pidgin.  If you’ve run Pidgin, even without creating an account, you will need to first remove its settings folder.  Click Start, the Run, and enter %appdata%. Delete your .purple folder. XP does not include a way to create a symbolic link, so we will use the free Junction tool from Sysinternals.  Download Junction (link below) and unzip the folder. Open Command Prompt (click Start, select All Programs, then Accessories, and select Command Prompt), and enter cd followed by the path of the folder where you saved Junction.   Now, to create the symbolic link, enter the following in Command Prompt, substituting username with your username. junction –d “C:\Documents and Settings\username\Application Data\.purple” “C:\Documents and Settings\username\My Documents\My Dropbox\.purple” Open Pidgin, and you will see all of your settings just as they were on your other computer.  Everything’s ready to go.   Please Note: If your primary Pidgin account is in Windows XP, then cut your .purple folder and paste it into your Dropbox folder instead.  Then, when creating the symbolic link, reverse the order of the folder paths. Conclusion This is a great way to keep all of your chat and IM accounts available from all of your computers.  You can easily access logs from chats you had on your desktop from your laptop, or if you add a chat account on your work computer you can use it seamlessly from your home computer that evening.  Now Pidgin is the universal chat client that is always ready whenever and wherever you need it!

  • Single Key Multiple Values Data Structure for one to many mapping

    - by nijhawan.saurabh
    Dictionaries are good, they are great to store Key / Value pairs but what if you want to store multiple values for a single key? Dictionaries would not allow duplicate keys. I came across a nice way to represent such a Data Structure using one of the Extension Method (ToLookup) present in System.Linq Namespace which converts an IEnumerable<T> to an ILookup<TKey, TElement>.   Now, there are two parameters this method expects (The other overload expects 3 parameters): IEnumerable<TSource> - This list would contain the actual data. Func<TSource, TKey> keySelector - The Delegate which which computes the keys   The method returns the following: ILookup<TKey, TElement>   This DS would store Keys and multiple values along those keys.   Let's see a small example:        12  using System;    13     using System.Collections.Generic;    14     using System.Linq;    15     16     /// <summary>    17     /// </summary>    18     internal class Program    19     {    20         #region Methods    21     22         /// <summary>    23         /// </summary>    24         /// <param name="args">    25         /// The args.    26         /// </param>    27         private static void Main(string[] args)    28         {    29             // Create an array of strings.    30             var list = new List<string> { "IceCream1", "Chocolate Moose", "IceCream2" };    31     32             // Generate a lookup Data Structure    33             ILookup<int, string> lookupDs = list.ToLookup(item => item.Length);    34     35           // Enumerate groupings.    36             foreach (var group in lookupDs)    37             {    38                 foreach (string element in group)    39                 {    40                     Console.WriteLine(element);    41                 }    42             }    43         } Normal 0 false false false EN-US X-NONE X-NONE /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin-top:0in; mso-para-margin-right:0in; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0in; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}

  • ATI graphics card overriding onboard Intel graphics

    - by Patrick
    I have an ATI graphics card with an AGP connection and a DVI port, and an Intel graphics processor on the motherboard with a VGA port. I have two monitors. When the graphics card is unplugged, I get this from lspci: 00:00.0 Host bridge: Intel Corporation 82G33/G31/P35/P31 Express DRAM Controller (rev 10) 00:02.0 VGA compatible controller: Intel Corporation 82G33/G31 Express Integrated Graphics Controller (rev 10) When it is attached, I get this: 00:00.0 Host bridge: Intel Corporation 82G33/G31/P35/P31 Express DRAM Controller (rev 10) 01:00.0 VGA compatible controller: ATI Technologies Inc RV380 [Radeon X600 (PCIE)] 01:00.1 Display controller: ATI Technologies Inc RV380 [Radeon X600] Note the absence of 00:02.0 - this is apparently causing the VGA monitor to say "No Signal" and the only the DVI display to show up in the list. I checked for problems in xorg.conf... there isn't one. I have no idea how to build one.

  • Graphics cards so I can have 4 monitors

    - by oshirowanen
    I currently have a single old graphics card to which I have connected 2 monitors giving me a big desktop of 2560x1024. If I get 2 of the following graphics card: http://www.ebuyer.com/238428-gigabyte-gts-450-1gb-gddr5-dual-dvi-mini-hdmi-out-pci-e-graphics-gv-n450-1gi Will I be able to connect to monitors per graphics card, giving me a total resolution of 5120x1024? I guess what I'm asking is, will I simply be able to stick both graphics cards in, plug the monitors in and will it all just work out of the box? I currently have 4 dvi monitors which have a native resolution of 1280x1024 each.

  • 2D grid with multiple types of objects

    - by Alexandre P. Levasseur
    This is my first post here in programmers.stackexchange (I'm a regular on SO). I hope this isn't too general. I'm trying a simple project to learn Java from something I've seen done in the past. Basically, it's an AI simulation where there are herbivorous and carnivorous creatures and both must try to survive. The part I am trying to come up with is that of the board itself. Let's assume very simple rules. The board must be of size X by Y and only one element can be in one place at one time. For example, a critter cannot be in the same tile as a food block. There can be obstacles (rocks, trees..), there can be food, there can be critters of any type. Assuming these rules, what would be one good way to represent this situation ? This is what I came up with and want suggestions if possible: Use multiple levels of inheritance to represent all the different possible objects (AbstractObject - (NonMovingObject - (Food, Obstacle) , MovingObject - Critter - (Carnivorous, Herbivorous))) and use polymorphism in a 2D array to store the instances and still have access to lower level methods. Many thanks. Edit: Here is the graphic representation of the structure I have in mind.

  • Samba Server Make Multiple User Permissions Profiles

    - by Scriptonaut
    I have a Samba file server running, and I was wondering how I could make multiple user accounts that have different permissions. For example, at the moment I have a user, smbusr, but when I ssh to the share, I can read, write, execute, and even navigate out of the samba directory and do stuff on the actual computer. This is bad because I want to be able to give out my IP so friends/family can use the server, but I don't want them to be able to do just anything. I want to lock the user in the samba share directory(and all the sub directories). Eventually I would like several profiles such as (smbusr_R, smbusr_RW, smbguest_R, smbguest_RW). I also have a second question related to this, is SSH the best method to connect from other unix machines? What about VPN? Or simply mounting like this: mount -t ext3 -o user=username //ipaddr/share /mnt/mountpoint Is that mounting command above the same thing as a vpn? This is really confusing me. Thanks for the help guys, let me know if you need to see any files, or need anymore information.

  • xgamma -display parameter for dual monitor setup

    - by Shiplu
    I want to change gamma for my first monitor. Every time I invoke xgamma with different -display parameters it somehow points to my second monitor. But I want to modify first one. I tried these commands. The parameters I have used for -display are :0, :0.0, :0.1, :1.0, :1.1, :1. Only the first 2 works. But it points to my second monitor. Not the first one. Here is a shell script to test it. shiplu@KubuntuD:~$ xgamma -display :0 -> Red 1.000, Green 1.000, Blue 1.000 shiplu@KubuntuD:~$ xgamma -display :0.0 -> Red 1.000, Green 1.000, Blue 1.000 shiplu@KubuntuD:~$ xgamma -display :0.1 xgamma: unable to open display ':0.1' shiplu@KubuntuD:~$ xgamma -display :1.0 xgamma: unable to open display ':1.0' shiplu@KubuntuD:~$ xgamma -display :1.1 xgamma: unable to open display ':1.1' shiplu@KubuntuD:~$ xgamma -display :1 xgamma: unable to open display ':1' How can I change the gamma for the first/primary monitor?

    I am trying to get a monitor work with my Ubuntu laptop. The monitor is this cheap 27" Korean monitors which has a 2560x1440 resolution -- and nothing else. Here are some specifications of this monitor: 2560x1440 @60Hz Only one dual link DVI-D input -- no other input port (no HDMI or display port) no OSD no scalar reports corrupt EDID does 2560x1440 @60Hz, did I say that already? Anyways, the monitor works beautifully with my Ubuntu desktop which has an nVidia card with DVI output. However, I am having problem using this monitor with my laptop. After some searching around I found a few posts suggesting to use an active adaptor for mini display port, so I went and bought a mini display to dual link DVI-D adaptor.. When using this adaptor the monitor is recognized by nvidia-settings tool but with incorrect resolution information. As you can see the monitor is incorrectly recognized and there are no other resolution available to set. This post on ubuntu forums and this other post on overclock both suggest that the monitor is reporting corrupt EDID file. I have tried following their instructions, but so far I have not been able to display any image on the monitor from my laptop. The laptop I am using is an ASUS G75VW with a 1920x1080 screen. It has a VGA, an HDMI 1.4a, and a mini display port. The graphic card is an nvidia gforce gtx 660M with 2GB dedicated memory. I am running Ubuntu 12.10 on here which I upgrade from 12.04 a few weeks ago. As I said I have tried several suggestions, including specifying Modeline in xorg.conf and also linking to EDID files I found from those forum posts above. However, I am not sure if the EDID files I found are suitable for my monitor. I think the solution to my problem consist of obtaining the EDID file of my monitor and then fixing it and modifying xorg.conf to force nvidia driver to load the correct resolution. However, I am not sure what steps I need to take to do this. Here is the part of sudo xrandr --prop output that is related to this monitor: DP-1 connected 800x600+1920+0 (normal left inverted right x axis y axis) 0mm x 0mm SignalFormat: DisplayPort supported: DisplayPort ConnectorType: DisplayPort ConnectorNumber: 3 (0x00000003) _ConnectorLocation: 3 (0x00000003) 800x600 60.3*+ I was expecting to see the EDID file in this output as was mentioned in this post, but it is not there. After several hours of tweaking X configurations, I decided it was time to ask for help here. I would really appreciate if someone with experience regarding EDID and X configuration could give me a hand to solve this issue.

  • Passing multiple Vertex Attributes in GLSL 130

    - by Roy T.
    (note this question is closely related to this one however I didn't fully understand the accepted answer) To support videocards in laptops I have to rewrite my GLSL 330 shaders to GLSL 130. I'm trying to do this but somehow I don't get vertex attributes to work properly. My 330 shaders look like this: #version 330 layout(location = 0) in vec4 position; layout(location = 3) in vec4 color; smooth out vec4 theColor; void main() { gl_Position = position; theColor = color; } Now this explicit layout is not allowed in GLSL 130 so I referenced this page to see what the default layouts for some values would be. As you can see position should be the 0th vertex attribute and color should be the 3rd vertex attribute. Because this is a test case I had already configured my explicit layouts in the same way, which worked, so I now simply rewrote my shader to this and expected it to work: #version 130 smooth out vec4 theColor; void main() { gl_Position = gl_Vertex; theColor = gl_Color; } However this doesn't work, the value of gl_Color is always (1,1,1,1). So how should I pass multiple vertex attributes to my GLSL 130 shaders? For reference, this is how I set my vertex buffer object and attributes (I've just adapted this tutorial to JAVA+JOGL) gl.glBindBuffer(GL3.GL_ARRAY_BUFFER, vertex_buffer_id); gl.glEnableVertexAttribArray(0); gl.glEnableVertexAttribArray(3); gl.glVertexAttribPointer(0, 4 , GL3.GL_FLOAT, false, 0, 0); gl.glVertexAttribPointer(3, 4, GL3.GL_FLOAT, false, 0, 4*4*4); gl.glDrawArrays(GL3.GL_TRIANGLE_STRIP, 0, 4); gl.glDisableVertexAttribArray(0); gl.glDisableVertexAttribArray(3); EDIT I solved the problem by querying for the layout locations of position an color using glGetAttribLocation however I still don't understand why the 'hardcoded' values like gl_Color didn't work, can't I upload data in there as normal? Shouldn't they be used?

  • Using the Onboard VGA output with a PCIe video card. Both nVidia

    - by sebikul
    I have 2 video cards, one On board, a nVidia 6150SE nForce 430 and a PCIe nVidia GeForce GT 220 1GB DDR2 RAM I have already configured the PCIe card to use the dual monitor feature, using the VGA and HDMI ports, but now I want to add a third monitor, using the On board VGA port I have managed to enable the On board graphics processor, which is taking 400MB of ram, but I cant manage to use it, nvidia-settings does not detect it, like it's not usable (but is there) My questions are the following: How can I manage to get the On board VGA display to work together with the PCIe graphics card? If possible, how can I recover those 400 MB the on board card is taking (even without being used) or how can I get it to use the PCIe card available memory? System Details: Linux 2.6.35-28-generic i686 Ubuntu 10.10 (All updates installed) NVIDIA Driver Version: 260.19.06 (Official) If more info is needed please let me know.

  • Permission issues causes Unity Segmentation fault

    - by Dj Gilcrease
    I upgraded from 13.04 to 13.10 and I can boot to the unity-greeter and login just fine, but after login I just get a black screen with a cursor. I have tried following http://help.ubuntu.com/community/BinaryDriverHowto/ATI http://help.ubuntu.com/community/RadeonDriver and the manual install of the downloaded AMD drivers. All have the same affect. Also I have read Black screen after login with cursor I get a black screen after logging in ubuntu 13.04 black screen after login Ubuntu 13.10 - Black screen after login session Ubuntu 13.04 - Black screen with unresponsive cursor Upgrade to Ubuntu 13.04 Problem - Boots into Blank Black Screen All of which were no further help then the two support articles about ATI drivers So I switched back to the default drivers and went a little further into debugging, when I do ctrl+alt+F1 and login and try unity --debug > unity_start.log then ctrl+alt+F8 the screen stays black with a cursor and when I switch back ctrl+alt+F1 the contents of the log output are http://pastebin.com/rdQG4Hb0 However when I try sudo unity --debug > unity_start_root.log then ctrl+alt+F8, unity starts and the output of the log is http://pastebin.com/Yv4RD2j7 The fact that it starts as root tells be it is either a permissions issue of some required file or there is some setting that is specific to my user that is causing the SIGSEGV. So to narrow this down I activated the guest account and tried to login and got the same black screens with only a mouse cursor, so this tells me that it is not a configuration issue, but a permissions issue, so how do I narrow down which file has the wrong permissions? Also is there anything further that may help debug this issue? Ok after a few more hours of googling I found that if I add myself to the video group I can login and see the desktop, but there are lots of other permission related issues, so I am thinking something went wonky with PolicyKit during the upgrade, is there a way to reset PolicyKit settings for a user?
