• Problems with dual monitor & resolutions, only in 14.04

  - by theLadder

  I installed Ubuntu 14.04 but i am having weird problems with my dual monitors and the resolutions. I also tried Xubuntu 14.04 and was having the same problem. I have one 32 inch LG TV with 1920x1080 and one monitor with 1280x1024 resolution. When i first start my 32 inch gets 1360x768, if i then try to change to 1920x1080, everythings looks fine and the prompt asking me if i want to keep settings comes up and starts the countdown, but after 2 seconds my computer freezes, and after a few more seconds it reboots itself. However, if i disable my smaller monitor first, i can change to 1920x1080 on my 32 inch without problems, but if i then activate the second monitor the same problem happens again. in Xubuntu 14.04 i can change the refresh rate, if i run the 32 inch at 30hz or 50hz everytying works, but i would like to be able to run it at 60hz. I'm currently running Xubuntu 13.10 without this problem. My graphics card is a ATI Radeon HD 4850. What is causing this problem, grahpics drivers? Kernel? Xorg? And how do i solve it?

• SCCM Client Push FAIL - Win2000 box

  - by ajp

  When trying to install the SCCM client onto a Windows 2000 box, the install fails. The install script is run through a batch file (CONTENTS: \mdop\SCCM_client\ccmsetup.exe /mp:MDOP /logon smssitecode=MID smsslp=MDOP) hosted on a public area of the network. This script has worked for all machines (mostly Win2003 Server). I've tried enabling all the common services it requires (BITS, IIS Admin, Windows Installer), but it still only runs for a second or two then quits. Here's the piece of the log file where it errors out: [LOG[Couldn't get directory list for directory 'http://MDOP/CCM_Client/ClientPatch'. This directory may not exist.]LOG]! time="13:55:53.618+300" date="06-30-2009" component="ccmsetup" context="" type="0" thread="1676" file="ccmsetup.cpp:6054" Full Log: http://paste-it.net/public/gb11732/

• Why no final dot for domain names?

  - by user41150

  I recently learned that a fully qualified domain name ends in a dot, e.g. www.microsoft.com.. Why do I almost never see this? We casually toss around www.microsoft.com, a relative domain name, without a second thought. It's not mere pedantry, because it seems there's a security issue: someone in your network could create www.microsoft.com.example.com. to hijack your requests to www.microsoft.com. Why doesn't the internet community have a tradition of using genuinely fully qualified domain names?

• Windows XP: How to boot up in normal mode after improper shut down?

  - by Nick

  I work in two different locations and whenever there is a power outage at one of the locations, Windows XP detects that the system was improperly shutdown. Once the power is up, the PC powers on and Windows XP enters REPAIR/SAFE mode where only someone physically in front of the PC can control it. (Networking is all disabled in this mode) Now before it enters REPAIR/SAFE mode, there is an option for a NORMAL boot. But the catch is that REPAIR/SAFE mode is selected by default with a 30 second timer. Once it automatically enters REPAIR/SAFE mode and if nobody is at the other location, I have no way to remote control it anymore. And then I have to drive over to the other location and reboot it and select boot into NORMAL mode. Where can I change this setting so that Windows XP always boots into NORMAL mode no matter how many times it is improperly shut down?

• Wifi and eth behavior

  - by r00ster

  I have a wireless router 150M Wireless Lite N Router Model No. TL-WR740N / TL-WR740ND. Normally, when I'm connected to the local network using eth0 I can ping other machines by issuing ping name. When I'm connected through wifi I have to issue ping name.domain.com. The machine is only visible in intranet. How to achieve the same behavior with wifi? The second problem is, that I can not connect to some external sites through wifi but through eth everything is ok. I guess that is related to some port forwarding, but I'm not sure. How can I resolve this issue? EDIT: I'm using Linux Mint.

• Windows 7 Incorrect Scaling

  - by Anonymous

  I ran into a problem the second after installing Windows 7 a few months ago, but it only affected a few applications at the time, so I ignored it. Now an increasing number of applications behave the same way and it's annoying. The DPI settings seem to have an issue as can be seen below: The same application should look like this: The DPI is set to 100% (I tried changing it but it had no effect). I think perhaps the Regional / Language settings have something to do with it but I can't turn it off to English only. Any ideas?

• What protocols will/are ISPs use for IPv6 deployment?

  - by rbeede

  Currently ISPs deal out addresses via DHCP for IPv4 dynamic (single) addresses. What protocol will/are ISPs going to use for IPv6 when they can hand a customer an entire /64 (or /48 if they are nice) block? DHCPv6, RA? For ISPs that support true end-to-end IPv6 will they provide gateway devices (similar to cable modem or true DSL bridges for example) that receive border information for that specific customer? I'm just trying to get an idea of how your common residential service customer will have to configure things in an IPv6 Internet (whenever that comes). Will it be something customers are expected to statically configure on their home wireless router? Today with IPv4 I do it like this: Modem (bridge) passes public IPv4 obtained via DHCPv4 from ISP to second device (wireless router). It in turn has its own DHCPv4 service it provides on the internal lan.

• How to convert excel individual cell values to percentage change values over time

  - by cgalloway

  I have two years of excel data showing daily share prices of a particular stock. I want to change those values to show percentage change (on a daily basis) from the zero date (ie the first day of the two year period). I know that the formula for showing daily percentage change would be (second day/first day -1) and that I can click and drag on that formula to extend over the rest of the two-year time period. The formula I want would be, basically, (each day/first day-1). Is there an easy way to automate the script so I dont have to type it out 730 times?

• Change Firefox theme locally with CSS (without any extension)

  - by Email

  I have some modifications I want to make WITHOUT installing extensions. eg: max width of tab and height of menu, In previous versions you could have it done via: about:config ->browser.tabs.tab.maxWidth Since FF4 it should be done with CSS. Now I searched the default theme: C:\Users\wetcat\AppData\Roaming\Mozilla\Firefox\Profiles\feriz.default and C:\Program Files (x86)\Mozilla Firefox In the second I could find the extension - theme but without any CSS. In the AppData I couldn't find any CSS or theme folder. WHERE is the file to create or alter the CSS?? I'm using Firefox 11.

• iptables to allow input and output traffic to and from web server only

  - by Caedmon

  I have an Elastic Search server which seems to have been exploited (it's being used for a DDoS attack having had NO firewall for about a month). As a temporary measure while I create a new one I was hoping to block all traffic to and from the server which wasn't coming from or going to our web server. Will these iptables rules achieve this: iptables -I INPUT \! --src 1.2.3.4 -m tcp -p tcp --dport 9200 -j DROP iptables -P FORWARD \! --src 1.2.3.4 DROP iptables -P OUTPUT \! --src 1.2.3.4 DROP The first rule is tried and tested but obviously wasn't preventing traffic coming from my server to other IP addresses so I was hoping I could add the second two rules to full secure it.

• initctl respawn does not reload configuration

  - by DELUXEnized

  My upstart service is running with the respawn option. I was hoping that if I deploy a new service config, the config will be loaded, when the service respawns. Neither the initctl reload-configuration command forces a reload, nor the restart command. Only an explicit stop and start reloads the configuration. The problem is, that I can not stop and start the service, at deploy time. The service itself schedules its restart by just shutting down. Is this behavior by design or am I missing something? Would it change anything, if I did the respawn with a second watchdog-service by an explicit start if my service stops? Why is there a difference between an explicit start/stop and the restart command or respawn option. Thanks.

• Analyse frequencies of date ranges in Google Drive

  - by wnstnsmth

  I have a Google Drive spreadsheet where I would like to compute occurrences of date ranges. As you can see in my sheet, there is a column date_utc+1 which contains almost random date data. https://docs.google.com/spreadsheet/ccc?key=0AhqMXeYxWMD_dGRkVGRqbkR3c05mWUdhYkJWcFo2Mmc What I would like to do is 1) put the date values into bins of 6 hours each, i.e. 12/5/2012 23:57:04 until 12/6/2012 0:03:17 would be in the first bin, 12/6/2012 11:20:53 until 12/6/2012 17:17:07 in the second bin, and so forth. Then, I would like to count the occurrence of those bins, such as bin_from bin_to freq ----------------------------------------------- 12/5/2012 23:57:04 12/6/2012 0:03:17 2 12/6/2012 11:20:53 12/6/2012 17:17:07 19 ... ... ... Hope it is clear what I mean. Partial hints are very welcome as well since I am pretty new to spreadsheeting.

• Vagrant sahara plugin - multiple snapshots

  - by BazZy

  How I can make more than one snapshot when in sahara sandbox mode? Or, can I see list of all commits I've ever made and rollback to any? Why do I need all this? I just want to setup initial VM. After that I want to compile number of packages from sources, and this takes pretty long time. So right now I thinking of this order: Setup initial ubuntu 12.04 vagrant box Snapshot this state Compile sources, install system wide rbenv (it make compilation also) Snapshot second state Start all my infrastructure experiments Rollback to any of my previous states or commit third state

• Do Loops kind of Reset every time you go through it?... [closed]

  - by JacKeown

  #include <iostream> using namespace std; int main (void) { cout << " 1\t2\t3\t4\t5\t6\t7\t8\t9" << endl << "" << endl; for (int c = 1; c < 10; c++) { cout << c << "| "; for (int i = 1; i < 10; i++) { cout << i * c << '\t'; } cout << endl; } return 0; } Hey so this code produces a times table...I found it on Google Code's C++ class online...I'm confused about why "i" in the second for loop resets to 1 every time you go through that loop...or is it being declared again in the first parameter? Thanks in advance!

• Mirroring a drive in Debian

  - by James Willson

  I have a drive with data on it. I dont want to use RAID, instead I want to do hourly backups to a second drive. I basically want to mirror the data drive and resync every hour. It is inefficient to re-move the data each time so really I only want to move across what changes. I.e if I add a new file to the data drive only that file will be moved across. What tools are there for doing this on the command line? I used to use luckybackup on Ubuntu but now im on commandline debian.

• Hipchat 2.2.1080 on ubuntu 64bit 12.04 flashes webcam on startup

  - by dm03514

  I recently updated to hipchat version 2.2.1080 and everytime I start it up it flashes the webcam. By this, I mean the light on my cam flashes. It flashes only for a second then turns off. Does anyone experience this? Does anyone know why this happens? It is rather unerving because other applications that support video chat, like skype, do no such thing. I have filed a help ticket directly with hipchat but until they respond I was hoping that someone knew what was going on Thank you

• How many xml http requests is too much for a pc to handle?

  - by Uri

  I'm running mediawiki on an apache on a regular pc running vista (don't know the specific specs, but I'm guessing at least duo core 2 2 giga hertz processor, broadband connection (500 kb/s at least, probably 1 mega). I want to use the MediaWiki api to send a lot of requests to this server. Most of the time the requests will be sent through LAN (but sometimes through the internet). I'm talking thousands of requests every few seconds at worst case. (A lot of these requests may repeat themselves, I guess some sort of cache would help) Will the server handle this, or do I need a stronger/dedicated computer? (I'm not looking for specific yes/no, but just want to get an idea as to what configuration of computer will support how many request per second) Thanks

• Mac OS X 10.6 Annoying Drag and Drop Behavior

  - by vaaaal

  In OS X 10.6 dragging a file(or folder) over another folder in Finder at first highlights that folder and allows you to drop it into the folder as one would imagine. The problem arises after about a second when it then removes the option to drag it over the folder and opens a new finder window with the contents of that folder for you to drag the file into. I personally find this feature very annoying and it often leads to me moving/copying files into a location I did not intend. I searched through com.apple.Finder for 'drag', 'drop', 'move', etc. with no luck. Does anyone know if there is a way to turn this off?

• SSH logins failing before success

  - by Vincent

  I am running Ubuntu 12.04 Server, updated, to run a webserver on Tomcat 7. I have about 1000 clients that are very very often using an RSYNC program to sync some file with this server. Those RSync are using SSH with a certain user to open connections on the server. The result is that my server is, as normal, full of connections by the same user. About 5 connections per 1 second every day any time. Then, when I try to open a regular SSH connection with my Putty client, the connection fails before login saying "Server unexpectedly closed network connection", about 6 times for 10 attemps, anbd for 4 attemps out of 10, it works normally and I am able to login as any user. Is there a overload of connections here? The server statistics are very calm saying less then 40% of network usage and less of 2% CPU. How can I improve this? Thank you for any help. V.

• Grub2 menu after crash

  - by poopa

  Hi, I have ubuntu 9.10 desktop VMware VM with the default grub2 installed. There is some weird problem with this VM. When you clone this vm and have a customization script run, the cloned machine crashes at first boot (VMware does not officially suport customizaing Ubuntu newer than 8.04). After the creash the Grub boot menu is displayed but there is not time out. I checked /boot/grub/grub.cfg and it does indeed show a timeout of 10 seconds. Nothing happens till I select an option with the keyboard. The second time the Ubuntu loads, it does not crash. My question is, how do I make the grub menu timeout in that case? Thanks.

• Create a Texture2D from larger image

  - by Dialock

  I am having trouble with the basic logic of this solution: Xna: Splitting one large texture into an array of smaller textures in respect to my specific problem (specifically, I'm looking at the second answer.) How can I use my source rectangle that I already use for drawing to create a new Texture2D? spriteBatch.Draw(CurrentMap.CollisionSet, currentMap.CellScreenRectangle(x, y), CurrentMap.TileSourceRectangle(currentMap.MapCells[x, y].TileDepths[4]), Color.FromNonPremultiplied(0,0,0, 45), 0.0f, Vector2.Zero, SpriteEffects.None, 0.91f); I know I want a method that I started so: //In Update Method of say the player's character. Texture2D CollisionTexture = ExtractTexture(MapManager.CurrentMap.CollisionSet, MapManager.TileWidth, MapManager.TileHeight); // In MapManager Class who knows everything about tiles that make up a level. public Texture2D ExtractTexture(Texture2D original, int partWidth, int partheight, MapTile mapCell) { var dataPerPart = partWidth * partheight; Color[] originalPixelData = new Color[original.Width * original.Height]; original.GetData<Color>(originalPixelData); Color[] newTextureData = new Color[dataPerPart]; original.GetData<Color>(0, CurrentMap.TileSourceRectangle(mapCell.TileDepths[4]), originalPixelData, 0, originalPixelData.Count()); Texture2D outTexture = new Texture2D(original.GraphicsDevice, partWidth, partheight); } I think the problem is I'm just not understanding the overload of Texture2D.GetData< Part of my concern is creating an array of the whole texture in the first place. Can I target the original texture and create an array of colors for copying based on what I already get from the method TileSourceRecatangle(int)?
