• Missing launcher after 12.04 upgrade

  - by Preston Zacharias

  I recently upgraded to ubuntu 12.04 and after doing some updates and such my application launcher and title bars (for window dialogues) are missing. Basically the entire unity GUI is missing! Not sure what happened so I installed gnome 3 and it was missing a launcher too, but did have title bars. In addition the bar found at the top that lets you know what's open and allows gnome extensions to be displayed is not interactive. I can't click, right click, alt + click (right or left), alt + super click (right or left) anywhere! I even installed an application menu from the gnome site and it is not interactive either. However, since there is no way to launch applications i have to use terminal and if i minimize an app it will disappear completely. Then i decided to try unity 2D and it is incredibly messed up. Black background, launcher is there but icons and top bar while on desktop are completely distorted. They're not just pixalated; they're all sorts of funky colors and when i open something from unity 2d launcher it will show it's opened in the launcher but nothing appears on my screen. When trying to view videos on youtube the video is distorted and looks just as unity 2d does. Strange enough: the audio works fine, just not videos. Pictures loads, but not ads that stream video. Any suggestions to get my launcher and the unity GUI back? I tried reinstalling gnome, unity 3d, and unity 2d from terminal. no change. also reinstalled unity desktop and tried resetting it: nothing happened.

• Using Kate with Simple Build Tool (SBT)

  - by Stefan

  Hello I am working with the Kate editor based on the lack of other good tools for Scala development, I am also using IntelliJ however it still has some bugs, and are slow enough to make me impatient. I have just startet using both Kate and SBT, and in that regard I have a little challenge I hope there is an answer for out there on "The Internet". I am using the standard "Build plugin" in Kate and has changed the commands from make to sbt. This works fine, and I am also getting a error report when the sbt fails during compile time. However I really wish to know if it is possible to integrate the compile errors into Kate such that it would be shown under "Errors and Warnings" instead of just in the output tab, where I have to do a manual search for the compile errors. Im guessing that it has something to do with the format of the output, if that is the case maybe it is "just" a smaller adjustment I need to make to the parsing language.

• How do I get Ctrl-Backspace to delete a word in vim within gnome-terminal?

  - by Michael Gundlach

  I'd like Ctrl-Backspace to delete the current word in vim insert mode. From within xterm I can pull this off via :inoremap <C-H> <C-W> but in gnome-terminal I cannot figure out a way to make it happen. When in vim insert mode, if I type control-v and then press backspace, I get ^H in xterm, and ^? in gnome-terminal. Unfortunately, :inoremap <C-?> <C-W> doesn't do the trick in gnome-terminal; control-backspace just erases a single character no matter what. Regarding ASCII codes: Gnome-terminal lets you change the backspace character under Edit - Profile Preferences - Compatibility. Unfortunately, no option works, as far as I can tell: whatever character I apply to Backspace via the settings, if I try mapping the character itself, like :inoremap <C-H> <C-W> then regular backspace and control-backspace both erase an entire word; and if I try mapping control plus that character, like :inoremap <C-^H> <C-W> then regular backspace and control-backspace just erase a single character.

• Windows Keys Extender – tool for XP/Vista users to using hotkeys Win+[Left|Right|Up|Down]

  - by outcoldman

  In Windows 7, I really liked an opportunity to change the position of the windows by pressing hotkeys Win + (Left | Right | Up | Bottom): Win + Left - window attached to the left side Win + Right - window attached to the right side Win + Up - window is maximized Win + Bottom - window in the normal state I’m talking about this: This is really useful hotkeys and really comfortable work with windows. But not all can use Windows 7 right now. When Windows7 was in beta and RC states I really wanted to use this features right now in current Windows version (I had Vista). So I spent my time and wrote this tool. In addition, the tool has functional which can change position of windows (It is useful for laptops, you can move windows with hotkeys). And of course this tool can move windows between monitors. Hot keys can be customized. Interface in English. Now I don’t want to add new functionality, because now I’m using Windows 7 with all functions that this tool have. I wrote this tool on C# with .NET 3.5. You can use this source code for knowing how to work with hotkeys with C#. At first I placed source code on Google Code and then placed it on CodePlex too. So you can download it from one of them. I would be glad if someone will use it. :)

• flickr, other account types not appearing in online-accounts

  - by Fen

  Using Shotwell, I discovered that to publish to Flickr I need to set up an online account. But the online-accounts system settings only has support for Google, Facebook, Windows Live, Microsoft Exchange and Enterprise Login (Kerberos). How do I add account types? These appear to be properly installed (dpkg-reconfigure returns silently): gnome-control-center-signon is already the newest version. account-plugin-yahoo is already the newest version. account-plugin-flickr is already the newest version. Here's the config file (I think): > cat /usr/share/applications/gnome-online-accounts-panel.desktop [Desktop Entry] Name=Online Accounts Comment=Manage online accounts Exec=gnome-control-center online-accounts Icon=goa-panel Terminal=false Type=Application StartupNotify=true Categories=GNOME;GTK;Settings;DesktopSettings;X-GNOME-Settings-Panel;X-GNOME-PersonalSettings; OnlyShowIn=GNOME;XFCE X-GNOME-Bugzilla-Bugzilla=GNOME X-GNOME-Bugzilla-Product=gnome-control-center X-GNOME-Bugzilla-Component=Online Accounts X-GNOME-Bugzilla-Version=3.4.2 X-GNOME-Settings-Panel=online-accounts # Translators: those are keywords for the online-accounts control-center panel Keywords=Google;Facebook;Flickr;Twitter;Yahoo;Web;Online;Chat;Calendar;Mail;Contact; X-Ubuntu-Gettext-Domain=gnome-control-center-2.0 History: Started out with Ubuntu (64-bit), then in 12.04 installed xubuntu-desktop and have been using that. Upgraded to 12.10.

• "dm-tool lock" doesn't lock my session

  - by cape1232

  When I use dm-tool to lock the screen for userA, I can log in as userB and then use dm-tool to switch back to userA's session without having to enter a password. Is that the expected behavior? If not, how should I switch from A to B without leaving userA exposed? userA$ dm-tool lock -- Shows Greeter. Login as userB. userB$ dm-tool switch-to-user userA -- Expected this to go to greeter, but it goes right back to userA's session. Do I have something mis-configured, or what?

• Default Save Directory for gnome-screensaver?

  - by trent

  Are there any sort of configuration options for specifying the default save location for gnome-screenshot, or is this hard-coded into the source code? It used to be ~/Desktop, which seems to have changed to ~/Pictures (in 12.04). The only possible solution I've seen is about Setting the default name (as it includes time stamp information now instead of simply Screenshot#), but that solution doesn't really seem ideal to me. Also, this post suggested that the last save location is remembered the next time you take a screenshot, but in my experience, this doesn't seem to be the case. And in any case, following on from that, that entry in gconf-editor doesn't even seem to accurately reflect the last location, so more than likely an entry related to an older version of gnome-screenshot.

• Can Unity be uninstalled?

  - by Dave M G

  Recently when doing an update, I noticed I was downloading a bunch of packages related to Unity. I use Gnome-Classic, and have no intention of ever using Unity. So, I thought I might save myself some bandwidth and download times (which can be slow on my laptop) by removing Unity. However, on next reboot, I could not get any form of GUI interface. Only by reinstalling Unity was I able to get the log in interface and get back into Gnome Classic. Can I get rid of Unity, or is it somehow now integral to Ubuntu in a way that makes Ubuntu not run without it (even if I'm exlusively using Gnome-Classic)?

• Custom Xsession with Gnome visuals

  - by Siim K

  I'm trying to create a kiosk PC only for web browsing using this tutorial as a reference (only difference - I'm using Firefox instead of Chromium) It is working correctly in principle (only FF window opens when I log in using the Kiosk session) but it looks, well, super ugly. The scrollbar and right-click context menus look like from the 1990s - gray and boxy. How could I modify the session to get Gnome-like scrollbars/menus without the whole Gnome desktop (top/bottom panel etc)? My custom X session is currently set up like this: /usr/share/xsessions/kiosk.desktop: [Desktop Entry] Encoding=UTF-8 Name=Kiosk Mode Comment=Firefox Kiosk Mode Exec=/usr/share/xsessions/ffKiosk.sh Type=Application /usr/share/xsessions/ffKiosk.sh: #!/bin/bash while true; do firefox -height 768 -width 1024; sleep 1s; done

• Gnome Mplayer failed to open VDPAU backend libvdpau_nvidia.so

  - by Tim

  When I open an avi file under Gnome Mplayer, there is an error report: Failed to open VDPAU backend libvdpau_nvidia.so: cannot open shared object file: No such file or directory I then followed this blog to solve this problem, which suggests two ways. The first way is to call mplayer in terminal: mplayer -vo xv video.wmv This works for me. But I would like to try the second way, which is to write options in one of the configure files of Gnome Mplayer. I choose to write into ~/.mplayer/config, where I wrote: -vo xv But it does not work. So I was wondering if I make any mistake? What to write into the configure file? Thanks and regards!

• SQL SERVER – Load Generator – Free Tool From CodePlex

  - by pinaldave

  One of the most common questions I receive is if there any tool available to generate load on SQL Server. Absolutely there is a fabulous free tool available to generate load on SQL Server on Codeplex. This tool was released in 2008 but it is still extremely relevant to generate the load on SQL Server as well works fabulously. CodePlex is a project initiated by Microsoft for hosting open source softwares. The best part of this SQL Server Load Generator is that users can run multiple simultaneous queries again SQL Server using different login account and different application name. The interface of the tool is extremely easy to use and very intuitive as well. One of the things which I felt needed improvement was a default configuration. As every single time when I was adding a query the default settings were showing up and I had to manually change that. However, when I went to Menu >> Tools >>Options I was really happy as it has options to change every single default which is available. Here one can give default username, password, database name as well various settings related to configuration. Additionally application logging is also possible through the options. A couple of other important points I noticed was the button to reset counters as well status bar containing useful information of Total Threads, Completed Queries and Failed Queries. I use this frequently for my load testing. What tool do you use for SQL Server Load Generator?

• How to get current gnome keyboad layout from terminal

  - by ftiaronsem

  For usage in a bash script, I need to get the gnome keyboard layout the user is currently using. For example if the user sets its keyboard layout to en-us , I need a bash command that prints me this. How can I get that information? Update: setxkbmap -query is unfortunatelly not working. Below is the ouput with the en (first command) and the de (second command) layout activated. Switching keyboard layout seems to be have some relation with gnome session configuration setxkbmap -query rules: evdev model: pc105 layout: us,de variant: , options: terminate:ctrl_alt_bksp,lv3:ralt_switch,grp:alts_toggle setxkbmap -query rules: evdev model: pc105 layout: us,de variant: , options: terminate:ctrl_alt_bksp,lv3:ralt_switch,grp:alts_toggle

• Difference left/right super button

  - by Erik Keemink

  When I press my left super key the gnome shell appears and when I press the right super key it does not. Moreover pressing right super + T does open a terminal at once, but when using left super I have to press the t twice, when I press the t only once it is similar to just pressing the t without holding super left. This last point also occurs with other shortcuts that I defined (like super+L, super+E), but not with super+up/down/left/right. What I want is to press either super key to get the gnome shell and to use either super key in combination with T to open a terminal immediately (and similar with other shortcuts). I use Ubuntu 12.04 LTS and the gnome 3 shell.

• Best C# and SQL server reporting tool [closed]

  - by user65439

  What is the best reporting tool to use with C# applications? I have been playing around with Pentaho (a Java based reporting tool) but would prefer to work with something that integrate better with my c# and SQL server. The reporting requirements are extensive and I need a tool that can generate graphs etc. and can be called from within my c# code to automate and email these reports. Perhaps the people that is more experienced with report generation can help me out with some of the better applications used with C#

• Disable auto-mount for particular partitions on usb drives

  - by nealmcb

  I have a big USB disk with 3 partitions: one for backup and two other bootable ones for installing and testing new distros. I want the backup partition automounted on boot. But I don't want the two test partitions automounted. Despite my use of "noauto" in /etc/fstab, something (gnome?) seems to be mounting them when I plug the drive it. LABEL=mybook /srv/backup ext4 defaults 0 2 LABEL=mybook-root /media/mybook-root ext4 user,noauto 0 2 LABEL=mybook-spare /media/mybook-spare ext4 user,noauto 0 2 In previous Ubuntu distributions it seems that it was possible to configure gnome so it would avoid mounting particular partitions on removable drives like USB: gnome-mount --write-settings --mount-options noauto --device /dev/sda1 This is no longer available in Lucid (when did it go away?) Is there another way to do this now?

• Why can't I get a working session with vnc4server

  - by ysap

  We have a couple of (identical) Ubuntu 11.10 machines, configured with gnome-classic, which we use as remote servers, and let our clients log into personal user accounts we create for them using vnc4server. We configured all the machines in the same way, following a short manual we compiled, describing how to download, install and prepare a few tools and our software. The connection usually works fine, but today I set up a fresh machine, and experienced problems. After installing vnc4server, I ran vncpasswd and copied the following startup file to ~/.vnc/xstartup: #!/bin/sh unset SESSION_MANAGER unset DBUS_SESSION_BUS_ADDRESS gnome-session --session=gnome-classic & [ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup [ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources xsetroot -solid grey vncconfig -iconic & Then, I started vnc4server and used two viewers (the Ubuntu Remote Desktop Viewer and Windows RealVNC Client) in two other machines, but instead of getting my desktop, I see an empty window with a grey-ish background pattern like this: and the cursor is a bold X. What is wrong with the setup and why don't I get a remote session as expected?

• 11.10 runs really choppy and slow, but not if I choose "Gnome Classic"

  - by Ingram

  I'd like to use Unity with Ubuntu 11.10, but everything from Unity runs really choppy and slow. I have an ATI graphics card and I have installed the drivers through "Additional Drivers". The drivers work, as I can play 3d games flawlessly. When I drag the mouse box around or drag windows around, it is really choppy. I previously had Ubuntu 10.10 and everything worked fine. I installed gnome 3 on 11.10 and it does the same thing Unity does, very choppy and slow graphics. However, if I choose Gnome Classic, everything is fine. I can drag the mouse box all around with no problems. I can drag windows around and it looks and feels great. Is this a bug with Unity? Are others experiencing this? Or is there something I can do to fix this?

• ALSA mixer applet?

  - by David Given

  I have recently installed Narwhal. Everything seems to look good so far, but as usual sound via PulseAudio is deeply unsatisfactory; scratchy sound from Skype, choppy sound from command line apps, etc. So I've removed it, and sound now works fine. Unfortunately I now discover that the standard Gnome mixer applet has changed to being PulseAudio-only, and trying to run it just hangs waiting for a PulseAudio connection. Does anyone know of a replacement volume control applet that I could use which manipulates the ALSA mixer directly? I've found xfce4-volumed, which handles the hotkeys very nicely (once I disable the keyboard shortcuts in Gnome), but of course the XFCE4 mixer applet isn't compatible with Gnome so I can't use that; and there appears to be nothing else readily apparent...
