• Ubuntu 11.10 Unity - all Windows decorations disappear after I maximize any window

  - by korda

  When I maximize some of the windows all decorations disappear (by all, I mean on all windows)... Is that common issue on Unity or I'm just unlucky to have some prone to that bug configuration? Anyone have idea how to fix this? EDIT: It won't fix after unmaximize. It seems like maximazing window simply crashes window decorator. Decoration isn't displayed for all existing windows and any new ones. Only way I found to fix this is to run compiz --replace (but this ruins current windows placement - all windows end up on same desktop). It happens almost every time I maximize window.

• DRBD stacked resources: recovering from failure

  - by Marcus Downing

  We're running a stacked four-node DRBD setup like this: A --> B | | v v C D This means three DRBD resources running across these four servers. Servers A and B are Xen hosts running VMs, while servers C and D are for backups. A is in the same datacentre as C. From server A to server C, in the first datacentre, using protocol B From server B to server D, in the second datacentre, using protocol B From server A to server B, different datacentres, stacked resource using protocol A First question: booting a stacked resource We haven't got any vital data running on this setup yet - we're still making sure it works first. This means simulating power cuts, network outages etc and seeing what steps we need to recover. When we pull the power out of server A, both resources go down; it attempts to bring them back up at next boot. However, it only succeeds at bringing up the lower-level resource, A-C. The stacked resource A-B doesn't even try to connect, presumably because it can't find the device until it's a connected primary on the lower level. So if anything goes wrong we need to manually log in and bring that resource up, then start the virtual machine on top of it. Second question: setting the primary of a stacked resource Our lower-level resources are configured so that the right one is considered primary: resource test-AC { on A { ... } on C { ... } startup { become-primary-on A; } } But I don't see any way to do the same with a stacked resource, as the following isn't a valid config: resource test-AB { stacked-on-top-of test-AC { ... } stacked-on-top-of test-BD { ... } startup { become-primary-on test-AC; } } This too means that recovering from a failure requires manual intervention. Is there no way to set the automatic primary for a stacked resource?

• Problem installing latest faience theme on ubuntu 14.04

  - by opensas

  I followed these articles to install the latest version of faience theme on ubuntu 14.04 http://www.webupd8.org/2014/06/popular-faience-gtk-gnome-shell-themes.html http://www.noobslab.com/2014/06/faience-theme-is-now-available-for.html And I'm getting the following error: Preparing to unpack .../faience-theme_0.7_all.deb ...

• Ubuntu doesn't find hdds with higher clock rates

  - by user136243

  I dual boot windows 7 64-bit and ubuntu 13.10 64-bit on separate disks, and utilize some overclocking from the BIOS. Windows works fine, however ubuntu can't seem to find any hard drives, except for at stock cpu speeds. While attempting to boot it says Gave up waiting for root device... and ALERT! /dev/sdb7 does not exist. Dropping to shell! A bootable usb stick still works, but gparted doesn't detect any other drives. Have tried: Boot-repair Changing SATA mode in BIOS Newer kernels Older ubuntu versions Not sure it's relevant, but the motherboard is a Gigabyte GA-A75M-UD2H with the newest BIOS version, the CPU an AMD Llano. This is hardly a fatal error, but it's inconvenient to change BIOS settings whenever I want to switch OS, and furthermore I'm quite curious about why it won't work. I'd appreciate any insight into what the actual problem is. So how can I resolve this issue ?

• Verify uniqueness of new content

  - by rogerkk

  I'm working on a review site, where there is a minor issue with almost duplicate reviews across items. Just a few words are changed. It would be very nice to be able to uncover these duplicates before they are approved by a moderator, and I'm hoping someone could chime in on the best strategy to get there. The site is running Ruby on Rails on a Postgres database and using Thinking Sphinx for search (all on Heroku), and so far the best option I see is to be pulling all the reviews out of the db and using a module like amatch to compare the strings. Not very efficient, so in this case I guess I'll have to limit the number/age of reviews to scan for dupes. Anyone got a better idea?

• Does NASA license the software that it develops?

  - by Abe

  NASA provides a visualization software called Panoply. There is a Credits and Acknowledgments page that acknowledges and lists the licenses of software dependencies, but provides no information about its own license. I have looked at other software produced by NASA, including the source code for GISS and can not find any information about a licence. The closest information that I can find is in the FAQ for the global climate model EdGCM Global that says the code is in the "public domain" is it standard practice at NASA to release code into the public domain? are there exceptions? Can I assume that Panoply is public domain and can be used without restriction other than than those imposed by licenses of software dependencies? Is the absence of specific permission to reuse the code a concern (this issue was raised in the answer to a separate question) How common is this practice across government agencies?

• Make UEFI, GPT, Bootloader, SSD, USB, Linux and Windows work together

  - by user129552

  I like to use the latest hardware and the latest software; thus I have a Laptop (Lenovo X220) with UEFI instead of BIOS an SSD instead of an HDD GPT partitioning scheme instead of MBR USB to boot from instead of optical disks. I need to use both Windows and Linux. I tried to make them work alongside, but I didn't succeed. Most Linux distribution isos don't even really work on UEFI systems booted from USB. (Not even the self-claimed cutting-edge Fedora. I also tried Linux Mint Debian Edition and Sabayon Linux (according to this guide) which did not work. Only Ubuntu worked for me. I first installed Windows 8 which created sda1: Recovery, sda2: EFI system, sda3: msftres, sda4: NTFS Windows. Windows worked without a problem. I then created sda5: linux-swap and installed Ubuntu into sda6: btrfs. After rebooting, I was not presented GRUB2 as expected, but instead my system just booted into Ubuntu. I could no longer access Windows. After fixing dpkg in btrfs Ubuntu, I followed the Ubuntu documentation on UEFI booting. The result left me with a broken GRUB2, but interestingly, when I wanted to select the device to boot from, I was not only presented the internal SSD, an attached USB device, or LAN, but also Grub2 (broken), Ubuntu and Windows. The result is not very satisfying to me. What would I have to do to fix everything? Or differently asked, what operating system should I install at what point given my possibilities and requirements, so that I have a working bootloader in my UEFI GPT system which presents me a working Linux and Windows.

• Banshee won't sync OGG format to my iphone

  - by Daze

  I have a jailbroken iphone 3g with 16 gigs of memory and I've been putting my music on it from banshee lately and have been having almost no issue. Unfortunately, I just added a few albums to my Banshee library and tried to sync them to my iphone, but every time I try, i see a hundred or so errors saying that the device doesn't support the ogg format and there was no converter found. I'm still pretty much a newb at this stuff, so please help me and dumb down your answer. I'm running 12.04 and again, using an iphone 3g with no sim card, but it's been jailbroken and is used primarily for it's music function.

• Can using an apt proxy (d-i mirror/http/proxy string http://mymirror) affect the installation of a .deb?

  - by Randolph

  I have been doing Ubuntu deployment using a preseed.cfg. After becoming comfortable with the packages being installed it was time to reduce download time and internet traffic by creating a mirror. I ended up doing a "partial mirror" using apt-cacher-ng and preseeding it by adding d-i mirror/http/proxy string http://mymirror to the preseed.cfg. This is where things got strange. I have a few .debs that I run as part of preseed/late_command by wgetting them and installing them with dpkg -i. The packages were installing without issue until added the proxy. With the proxy they fail to install. So does the proxy affect installing .debs during preseeded installation?

• Windows 7 DVD doesn't boot up, neither does USB. :'(

  - by Manan Shah

  My problem is that i'm not able to install windows 7. Been trying to install this since past 1 week. The methods i've tried are: I have a windows 7 bootable DVD which doesnt boot up. (I've set BIOS to boot from DVD ROM first but it just won't boot from the DVD). Tried to install Windows 7 from the same DVD to a friend's PC and it worked. So the DVD has no issues. I tried to run 'Setup.exe' from within the DVD. The two options pop-up 'Check compatibility' and 'Install now'. On clicking install now, after sometime, an error is encountered with the message 'Windows was unable to create a required installation folder' error code:0x8007000D. I am running Windows XP Professional and there's only one user on the PC which is the Admin, so i do not know why is the setup not getting permissions. I've also uninstalled my antivirus, CD burning software, disabled firewall and disconnected all other devices, but its still the same. I tried to install it from a USB device by making it bootable but that too doesnt work. (Yes the mobo supports booting from the USB). The problem is that XP does not recognize a 'USB' device on boot. Rather it shows this USB stick as a removable 'Hard Drive'. Furthermore, i changed the order of Hard Drive boot to boot from this removable Hard Drive first, it still boots my existing OS. Is there anything else that can be done? Any help would be greatly appreciated. :) Please ask if any other information is required, this post is becomimg increasingly long to add any other details. PS: I want to dual boot windows 7 with my existing XP, but that would be after i manage to run the windows 7 setup in the first place. PPS: Please bare with any 'not-so-technical' terms, i am a beginner with this. Again, thank you for taking the time and trying to help, really appreciate it. :)

• Closing lid does not suspend laptop

  - by fgysin

  I'm on a Lenovo T400 laptop. In the past I had suspend problems on every second version of Ubuntu (at least it feels like it), but in 11.04 it was working perfectly. Now, after the upgrade to 11.10 closing the laptop lid does no longer initialize suspension. When I choose 'Suspend' from the shutdown menu it works perfectly, so this does not seem to be an issue with suspend itself. The options in System Settings>Power are of course set to suspend in case of closing the lid (both for battery and AC poer). Note: I have no idea if this is of any importance, but I'm running the gnome-session-fallback stuff, as I just hate the Unity desgin.

• Terminal flashing between current and previous screen

  - by cjordan1

  I just upgraded from Ubuntu 12.04 to 14.04. After upgrading the terminal will sometimes, but not always, flash between the current screen and the previous screen. Here are some examples: The output of an 'ls' command will flash on and off the screen. But when I press enter to start a new line, sometimes--but not always--the output of ls will stop flashing and instead the newline will begin flashing. Sometimes vim will start flashing between the current place and a previous place, such as right after a search. This also happens when I opened just sh within a bash terminal. (I was hoping the issue was just with my .bashrc, though I haven't changed it in months and didn't have any issues in 12.04.) This is incredibly annoying, and has made the terminal essentially unusable.Unfortunately, google-ing for a half hour hasn't shown anyone running into similar problems, either on 14.04, other versions of ubuntu,or other versions of linux.

• SATA DVD drive refuses to read movie DVDs

  - by poke

  Hey, I have a problem with my DVD Drive (Asus DRW-2014L1T, most current firmware installed) on Windows 7 x64. When I insert a DVD movie and Windows starts to access the drive (for autoplay, or when I manually click on the drive icon), my computer hangs up in a particular way, while trying to read the disk. Explorer stops reacting and several programs won't run or their launch is horribly delayed (like the device manager). In th end, I can't access the movie and can't even eject the disk (probably because Windows is still trying to access it). To get the disk out of the drive I then have to reboot (which sometimes doesn't work either) and eject the disk before Windows boots. BIOS recognizes the drive just fine, and Windows is also able to read data disks (tried it with some software disks), but just refuses any movies. I have checked the region code in the device manager, but it is correct. My notebook is reading the disks just fine btw.. I remember having the same problem with an older drive as well, but I don't remember what I did to make it work again (maybe I didn't even fix the problem back then). I do remember however that booting with the disk inserted made Windows recognize the disk, however this doesn't work in this situation either. Do you have any idea what to do to fix that problem?

• Are two database trips reasonable for a login system?

  - by Randolph Potter

  I am designing a login system for a project, and have an issue about it requiring two trips to the database when a user logs in. User types in username and password Database is polled and password hash is retrieved for comparative purposes (first trip) Code tests hash against entered password (and salt), and if verified, resets the session ID New session ID and username are sent back to the database to write a row to the login table, and generate a login ID for that session. EDIT: I am using a random salt. Does this design make sense? Am I missing something? Is my concern about two trips unfounded? Comments and suggestions are welcome.

• Does HTML5 have a feature that enables a user to add an icon to the Apps screen when "installing", and if not, when are they planning to add it?

  - by Jason Livesay

  I know that the mobile bookmark bubble might sort of work for iOS, but it isn't going in the same section. And for Android, bookmarking is really not going to cut it for a mobile HTML5 application install since users just don't think to go to their bookmarks and that bookmark process takes two or three steps. To me this issue of getting the application (bookmark) installed pretty much makes the rest of the HTML 5 features aimed at mobile HTML much less useful. I can't realistically expect users to prefer the bookmark install and launch process over regular apps, so I can realistically expect them to ignore my mobile HTML5 application and use a native app. The groups behind mobile HTML 5 features do seem to be pushing for HTML 5 apps adoption with things like Application Cache etc. To me it seems obvious that the bookmark bubble is not going to cut it. Someone please tell me they have addressed this or at least are working on it?

• Not Quite Multiseat

  - by user2773520

  I am attempting to create a pair programming environment sort of set up like multiseat: https://help.ubuntu.com/community/MultiseatX[1] or https://help.ubuntu.com/community/MultiseatOneCard[2] (as the standard issue boxes only have one graphics card) The thing is, I only want one login session, just with 2 monitors, keyboards, and mice. As well as having 2 active applications (so 2 people can be typing independantly). They should ideally be able to mouse over and click & type in the other persons monitor, as well as move windows between the montors. Does anybody know of anything like this that will work? We are running Ubuntu 12.04.

• VMWare ESXi 5 - Expanded RAID 5 array - cannot access datastore

  - by Dayton Brown

  I'm using VMWare ESXi 5 and had a 2 TB RAID 5 setup on an HP DL360 with a P400i RAID card. I added two more 1 TB drives and using the SmartStart ACU, added the drives and expanded the logical disk. Now after booting back to ESXi, the server boots, but lists no available persistent storage. I've rescanned multiple times to no avail: the Datastore doesn't show up. I booted to GParted and the 1.8TB partition shows up, but it shows as unknown. Anyone have any good ideas? EDIT: Final Solution So after much gnashing of teeth, it was fairly simple to solve. I purchased an eSata 2 TB external drive and a PCI eSata card for my server. I then used Clonezilla to image the current partitions to my new external drive. You have to check "don't check drive sizes" in advanced mode, otherwise it will yell at you for have a smaller drive. For some reason my PCI card wouldn't boot on my HP server, so I hooked the drive up to another desktop I had, booted to VMWare, and copied the vmdk's to another drive. I'm going to blow out the RAID config and then create 1.5TB logical drives.

• Broken Links in different browsers

  - by kdorival

  Hi I'm having problems with our website, http://www.accessiblehomehealthcare.com, which is a wordpress 2.7 (version). All of a sudden our RSS links broke on the right side, which has happened before and I fixed it within 5 mins. Now, when I fix it, it doesn't look right in different version of I.E. or Firefox, I have I.E. 8 and Firefox 3.6.15 and it looks good for the most part, but there are a few parts where the links are broken. One browser the links would look ok but go to another page and the links or logos would be broken. Certain parts of the website should be static(identical) to the other pages of the site, but if a link is broken on one page, its perfect on another page. I was wondering was there a secret code for wordpress to keep the sites compatible with all browser versions or is there a bigger issue???? Any help or suggestions will help???

• User Already Exists in the Current Database - SQL Server

  - by bullpit

  I was moving a lot of databases from one SQL Server to another, and my applications were giving me errors saying "Login failed for <user>". The user was already in the database with appropriate rights to allowed objects in the database. I tried mapping the user to the database and that's when I got this message: "User Already Exists in the Current Database"... I googled and found this very useful post about orphaned users when moving databases. These are the steps you should take to fix this issue: First, make sure that this is the problem. This will lists the orphaned users: EXEC sp_change_users_login 'Report' If you already have a login id and password for this user, fix it by doing: EXEC sp_change_users_login 'Auto_Fix', 'user' If you want to create a new login id and password for this user, fix it by doing: EXEC sp_change_users_login 'Auto_Fix', 'user', 'login', 'password'

• Dropbox icon dissapears right after login

  - by garvamel

  Even though Dropbox's app indicator dissapearing from the tray area seems like a recurrent enough problem, my issue is a litte different. When I login, I can see the app panel populating, and the dropbox icon does indeed appear (config'd as startup application), but after some other icons show up (bluetooth, battery, etc.) it's gone. It's still running though. I'm guessing it's having issues with staying pinned, and I don't know how to start addressing this problem. I have tried many if not all solutions provided here in the forums for the "icon missing" questions. So far: I've whitelisted everything regarding panel Uninstalled-reinstalled (with and without rebooting in between) Overwritten current installation Purged installation from terminal Installed from Software Center and from .deb file batch deleted every "dropbox" ocurrences from terminal (files and folders) and reinstalled Ran sudo apt-get install libappindicator1, it installed, but didn't solve anything I'm on Ubuntu 12.04 LTS - 64 bits. Any insight would me much appreciated!

• Bad texture on model with different GPU

  - by Pacha

  I have some kind of distortion on the texture of my 3D model. It works perfectly well on an AMD GPU, but when testing on a integrated Intel HD graphics card it has a weird issue. I don't have a problem with the rest of my entities as they are not scaled. The models with the problems are scaled, as my engine supports different sizes for the platforms. I am using Ogre3D as rendering engine, and GLSL as shader language. Vertex shader: #version 120 varying vec2 UV; void main() { UV = gl_MultiTexCoord0; gl_Position = gl_ModelViewProjectionMatrix * gl_Vertex; } Fragment shader: #version 120 varying vec2 UV; uniform sampler2D diffuseMap; void main(void) { gl_FragColor = texture(diffuseMap, UV); } Screenshot (the error is on the right and left side, the top and bottom part are rendered perfectly well):

• Are these GitHub features implemented in BitBucket?

  - by doug

  I recently joined a company that, while using git for version control, uses BitBucket as remote/master + git interface for projects. This is my first exposure to BitBucket. There are a couple of GitHub features I rely heavily on in my daily workflow and I am trying to find their counterpart in BitBucket or else how I can recreate the same functionality if it is not provided out-of-the-box. In particular, in GitHub I rely heavily on tags (which I realize reside in git) to link commits to issues (feature request, bug report, etc.); in addition, given projects specs are often decomposed into milestones, I use the milestone feature in GitHub Issues to track progress towards our project milestones (ie, in GitHub a milestone is comprised of a sequence of issues, and the commit tagged with the last remaining issue under that Milestone, causes that Milestone to be annotated as completed. I suspect this workflow can be recreated using Jira, which my new employer also uses, but before trying that, I want to learn if it's already implemented and I just can't find it.

• Using .add() on the same widget more than once

  - by Dillon Gilmore

  I asked this question on Reddit and was directed here. http://www.reddit.com/r/Ubuntu/comments/vhadl/quickly_dynamic_ui/ Unfortunately I am having the same issue and the problems seems that you can only use .add() on a widget once. So here is my code, self.ui.labels = [] for titles in entries: label = Gtk.Label() self.ui.labels.append(label) self.ui.viewport1.add(self.ui.labels[-1]) self.ui.paned1.show_all() Now, for fun I decided "What would happen if I just manually did..." self.ui.viewport1.add(Gtk.Label()) self.ui.viewport1.add(Gtk.Button()) self.ui.viewport1.add(Gtk.Entry()) For my first code snippet I get this error, Gtk-CRITICAL **: gtk_viewport_add: assertion gtk_bin_get_child (bin) == NULL' failed The error happens an unknown amount of times because the list entries can vary in length, but for my second code snippet it happens exactly twice. This means that when I viewport1.add() it works the first time, but all adds after that receive the error above. So my question, is there a way in python to use .add() on the same widget more than once?
