• Why is the file /var/crash/_usr_lib_empathy_empathy-chat.1000.upload empty?

  - by user43816

  I just experienced an unusual crash: I tried to click on a name entry in the contact list of Empathy. A crash happened. Usually I am asked then if I'd like to report the error to Launchpad, and Launchpad opens. This time the error message was: "Excuse me. Ubuntu 12.04 noticed an internal error. If you notice further problems try to restart your computer. Send an error report to Launchpad to help removing this problem?" This time Launchpad did not open automatically. A new window opened and I could read the relevant error report. Later I found the error report in the file /var/crash/_usr_lib_empathy_empathy-chat.1000.crash. Why went the course of action this time differently from other crashes? Why is the file /var/crash/_usr_lib_empathy_empathy-chat.1000.upload empty?

• Can't disable giant cursors (from accessibility mode)

  - by jackweirdy

  I've just installed ubuntu 12.04 from a livecd. Out of curiosity, I enabled the accessibility options for people who are hard of sight. As you can guess this does the usual stuff of inverting colours, increasing text size and making the cursor larger. Having finished the installation I booted into the new system to find accessibility mode was still installed. From the lightdm login screen I disabled this which switched colours and text size back to default, however it's only the pointer cursor that has gone back to default. To put it another way, the "hand" icon that you get when hovering over a link, the cursor which appears when typing and pretty much every other cursor on the system are still large. I've looked on the Universal Access menu, but there's no option to disable large cursors. I've tried toggling accessibility on and off but to no avail.

• How can I make the text cursor in X Windows easier to see?

  - by skyblue

  The text cursor in X Windows is too thin for me to see easily. It would be great if I could make the text cursor wider so that it was more visible. I know how to change the size of the mouse cursor in X by going to System Preferences Appearance and customizing the Pointer so that it is larger. But I have not been able to find any setting that allows me to alter the appearance of the text cursor. So how can I make the text cursor easier to see?

• Home directory messed up

  - by nuthan

  Recently, I installed Ubuntu 12.04. For some reason, i backed-up my home directory contents to another directory(say bkp dir). Precisely, I moved Documents, Pictures, Downloads, etc.. to bkp directory. Now, Deleted all my original home directory contents. I restored all the bkp directory content back to home. I find them all on my Desktop. I believe some kinda chain is broken. I dont find respective home directories icons on them. How do i restore it? Also, i dont find them in my places options. Messed up image link Thanks... ls -lh ~ ~/Desktop nuthan@nuthan-desktop:~$ ls -lh ~ ~/Desktop /home/nuthan: total 2.8M drwxr-x--- 11 nuthan nuthan 4.0K May 28 20:05 android-sdk-linux drwxrwxr-x 4 nuthan nuthan 4.0K May 25 13:36 android-sdks drwxrwxr-x 2 nuthan nuthan 4.0K May 18 17:30 convert -rw-rw-r-- 1 nuthan nuthan 0 May 30 09:07 dependancies~ drwxr-xr-x 2 nuthan nuthan 4.0K Jun 6 14:16 Desktop drwxrwxrwx 6 nuthan nuthan 4.0K Jun 6 12:06 Documents drwxr-xr-x 28 nuthan nuthan 12K Jun 6 13:52 Downloads drwxrwxr-x 2 nuthan nuthan 4.0K Mar 6 13:23 examples -rw-r--r-- 1 nuthan nuthan 8.3K May 11 16:19 examples.desktop drwxrwxr-x 4 nuthan nuthan 4.0K May 18 19:04 github -rw-rw-r-- 1 nuthan nuthan 0 May 28 18:40 linux~ drwxr-xr-x 2 nuthan nuthan 4.0K May 11 16:46 Music drwxrwxr-x 2 nuthan nuthan 4.0K May 30 08:48 node-code drwxrwxr-x 4 nuthan nuthan 4.0K May 30 08:40 node_modules drwxr-xr-x 7 nuthan nuthan 4.0K May 25 13:55 noduino drwxrwxr-x 2 nuthan nuthan 4.0K May 30 11:58 nuthan drwxrwxrwx 3 nuthan nuthan 4.0K May 24 11:13 Pictures drwxrwxr-x 6 nuthan nuthan 4.0K Mar 6 13:23 public drwxr-xr-x 2 nuthan nuthan 4.0K May 25 11:44 Public drwxrwxr-x 2 nuthan nuthan 4.0K May 29 18:50 python -rw-rw-r-- 1 nuthan nuthan 983K Jun 6 14:16 Screenshot from 2012-06-06 14:16:37.png -rw-rw-r-- 1 nuthan nuthan 980K Jun 6 14:20 Screenshot from 2012-06-06 14:20:24.png -rw-rw-r-- 1 nuthan nuthan 731K Jun 6 14:22 Screenshot from 2012-06-06 14:22:06.png drwxrwxr-x 3 nuthan nuthan 4.0K May 31 18:17 sketchbook drwxrwxr-x 2 nuthan nuthan 4.0K Jun 6 13:05 sql -rw-rw-r-- 1 nuthan nuthan 201 May 28 22:08 sql~ drwxr-xr-x 2 nuthan nuthan 4.0K May 11 16:46 Templates -rw-rw-r-- 1 nuthan nuthan 5.1K Jun 4 12:29 test~ drwxrwxr-x 3 nuthan nuthan 4.0K May 14 11:09 Titanium_Studio drwxrwxr-x 4 nuthan nuthan 4.0K May 14 21:00 Titanium Studio Workspace drwxrwxr-x 4 nuthan nuthan 4.0K Jun 1 18:29 TPM_Trak drwxrwxr-x 2 nuthan nuthan 4.0K May 24 17:30 Ubuntu One drwxr-xr-x 2 nuthan nuthan 4.0K May 11 16:46 Videos drwxrwxr-x 6 nuthan nuthan 4.0K May 31 15:10 workspace drwxrwxr-x 3 nuthan nuthan 4.0K May 14 11:57 Zend /home/nuthan/Desktop: total 20K -rw-rw-r-- 1 nuthan nuthan 441 May 30 09:07 dependancies -rw-rw-r-- 1 nuthan nuthan 1.6K May 28 18:40 linux -rw-rw-r-- 1 nuthan nuthan 470 May 28 22:16 sql -rw-rw-r-- 1 nuthan nuthan 5.1K Jun 4 19:34 test nuthan@nuthan-desktop:~$

• Cannot activate num pad at all

  - by ubuntico

  I have two accounts on the same machine. Num pad on one account it working normally e.g. I can turn it ON/OFF via NumLock button. The num pad on the other account on this machine stopped working. I cannot turn it on and the buttons work as the NumLock is turned off. This happened without me touching any setting or all. It just happened and now I cannot turn them on no matter what I try. I tried via console command numlockx on - did not help. Tried via UI setting - did not help either. Updated the system from 11.10 to 12.04, did not help either. I really do not know what to do except I make a clean reinstallation of the system which would take 2 days away from me. It's obviously the problem in this account only, as num pad works in the other account. Anyone with a good suggestion?

• A terminal emulator for ex-Windows users

  - by Dan

  There are several things I would like to be better in Ubuntu Terminal Emulator. coloring, like in the source code Copy and paste keyboard shortcuts that I used all the time in Windows: Ctrl-C and Ctrl-V (Most of people here in Ubuntu use Ctrl+C and Ctrl+V keyboard shortcuts to copy and paste everywhere except the terminal! I think it's annoying for newcomers, and I don't worry about historical reasons) A feature to save all the output to log file UPDATE: Can the terminal be a powerful feature-full user-friendly tool like a modern IDE? The Linux user can spend 30% of time in the terminal. Programmers no longer code in a notepad. Can I see the history pane? Suggestions? Directory pane? Commands list? Search for words in an output? Contextual behavior? "Search in Google" for a mouse right-click. Tips and tricks learning? Time is money! Please, people, give me a link to the 21st - century terminal.

• I am so confused about desktop/viewport switching, all I want to do is bind keyboard shortcuts to switch desktops

  - by Alex

  I've installed a pre-made Ubuntu 10.04 image at work, and I can't seem to figure out how to get desktop switching to work. No shortcuts work, and all the help I can get from the Ubuntu forums is "CTRL-Alt-Left/Right should work." So lemme get this straight. Switching between desktops is deprecated, so we use viewports, which are managed by Compiz, which has one of the most absurd configuration managers out there. Lovely. Can anyone straighten this out for me, and anyone else who might stumble on this question?

• How can I get back my deskopt? the left and top panels

  - by Hunsullivan

  I installed the Ubuntu 12.10 and the driver for ATI Radeon HD 4330 (AMD Catalyst™ 12.6 Proprietary Linux x86 Display Driver) and the latest updates. After the restart now I can see only the deskopt backgrund and nothing more. No left or top panels. The resolution changed to 1024X768 and the graphic changed to: VESA:M92. What happened? Is there something wrong with the driver? How can I solve this? I'am a beginner, please answer according to this. Thank you!

• Why is it taking so long to open the Ubuntu Help Center?

  - by Agmenor

  When I click on the Help Center Icon in the 'System' menu, it takes more than a minute to launch the program. More than a minute, for a text only program seeming like a website! All my other programs work fine, and I saw this problem also on other computers. Is there a reason for this? Will it be fixed? I think it is an important issue for beginners. As a response to Scaine, the result of the command software-center is the following: Traceback (most recent call last): File "/usr/share/software-center/update-software-center-agent", line 72, in <module> db = xapian.WritableDatabase(pathname, xapian.DB_CREATE_OR_OVERWRITE) File "/usr/lib/python2.6/dist-packages/xapian.py", line 3195, in __init__ _xapian.WritableDatabase_swiginit(self,_xapian.new_WritableDatabase(*args)) xapian.DatabaseLockError: Unable to acquire database write lock on /home/agmenor/.cache/software-center/software-center-agent.db.tmp: already locked 2011-01-11 19:57:24,495 - softwarecenter.app - INFO - software-center-agent finished with status 1

• Indicator applet-less applications?

  - by armornick

  Since I heard that indicator applets are going to replace the notification area, I wondered what was going to happen to applications that use the notification area and don't have an indicator applet? Is the Ubuntu team going to write an indicator applet for every application out there? You can't expect the developers of applications to add that Ubuntu-only task to their list. Don't get me wrong, I love the indicator applets. But I'm a little concerned about this.

• How to fix missing menus in non ubuntu maverick apps

  - by piedro

  Hi! There's a bug with the menue of filezilla: When opening filezilla there is no menue list. Very inconvenient because you can't open the "settings"-dialog. There are several workarounds that I tried - none of them really work. change theme while filezilla is running, menue reapperars. Once you close and reopen it the menue is gone again. add "export UBUNTU_MENUPROXY=0" " to .bash.rc or just call it before starting filezilla. Doesn't have any effect for me - menue still missing. tried "sudo apt-get remove appmenu-gtk" cause it's obviously to do with unity but the funny thing is even this method has bo effect at all! How can I fix this? How to do the troubleshooting? thx fior reading, p.

• Confused about what makes up the Ubuntu GUI

  - by RafLance

  I am now getting more into customizing my Ubuntu experience and want to understand better what all these different things I keep running into are. What is Gnome3 and Gnome2 in relation to GTK3 or GTK2? Are they related at all? Is Gnome3 another version of Unity? What is Unity? What is compiz? To make this all VERY basic, the core question is: How is the Ubuntu GUI built? What are the elements from the bottom-up that make up the desktop environment? Trying to understand this better so I know what I need/want in order to have my desktop the way I would like it. If this question is better suited for a forum of some sort, please let me know and I will understand completely. Thanks in advance!

• Menus intermittantly take two clicks

  - by heynnema

  Intermittently, when I left-click on the Applications/Places/System menus, the first click does nothing, and it takes a second click to drop the menu. I've also noticed that hiarchial menus sometimes don't show their expanded menus unless I move the mouse pointer away to another menu item, and then come back into the hiarchial menu. And lately, I've even noticed that in some applications, menus are acting the same way. Any ideas? Cheers, Al

• Application specific environment variable settings

  - by SuperElectric

  I'm trying to work around a known bug in Ubuntu 9.10, where using the scrollbar in emacs causes text to be highlighted, and the cursor to move. This page here shows that you can fix this by setting an environment variable before launching emacs: $ GDK_NATIVE_WINDOWS=1 emacs So a lazy fix would be to alias "emacs" in my .bashrc: alias emacs="GDK_NATIVE_WINDOWS=1 emacs" This, however, has the drawback of setting this environment variable for all subsequent commands run from that shell. Is there any way to set GDK_NATIVE_WINDOWS=1 for just emacs, whenever I run emacs?

• Is it possible that Unity would some day switch back to Mutter?

  - by David

  I remembered that the first Unity was indeed built on Mutter, but later ported to Compiz due to poor performance. I also know Canonical practically incorporated Compiz to work closely for future Unity, so this is getting less likely. But Compiz just seems pretty outdated now that GNOME3/GTK3/Mutter is becoming more mainstreamed, and it is known to deliver some performance issue, but on the other hand Mutter seems pretty good and is still steadily developing now, I'm just wondering if anyone related to the project is still testing and evaluating the possibility of Unity on Mutter? Not that you have to tell me now if you're going to do it or not. I just wanna know if anyone is considering it. Thanks.

  What Language is Unity written in? Also, where can i get its source code? I have an idea for a windowing enviroment or shell (dont know what to call it). What i want to do is teach myself to create it. i like some of several ideas i have seen, but i want to redo all of them, also the concept of how a desktop works. I figured learning the language Unity is written in, and studying Unity and Gnomes code would be a good start. i am on Ubuntu 12.04 acer aspire 5920 3 gb ram 160 gb hard drive

• Is there a way to open an "extra" temporary workspace (via terminal, preferably)?

  - by AmagicalFishy

  [Running Ubuntu 14.04, Unity] So, I have workspaces enabled and all that jazz. I know one can set some option so that Ubuntu defaults to more than four workspaces—but that's not what I want. Currently, I'd like a fifth workspace, but only temporarily (that is, I don't want it to be the default that five open. I just want it for today, and possibly w/e other day I need it). Is there a way to do this?

• How to identify process that's sending error messages to terminal?

  - by kjo

  The following error message occasionally appears in my terminal: Failed to open VDPAU backend libvdpau_nvidia.so: cannot open shared object file: No such file or directory ...which is pretty annoying. I have searched online for solutions to this error, without success. Is there any way to at least identify the process responsible for sending these error messages to my terminal? EDIT: Let me clarify that, as far as I can tell, these error messages appear "out of the blue". In fact, they appear asynchronously with respect to my interactions with the terminal (more often than not see them for the first time when I return to a terminal window that has been unattended for some time). I'm sure there's a definite, deterministic cause for these messages, but it is not one that I can readily identify. In short, I have not noticed any pattern or regularity to their occurrence. In particular, in my case their occurrence has nothing to do with running mplayer, or any other video playback program. (Please my earlier post about it here.) For one thing, the machine in question is a work machine, and I rarely watch any videos with it. In the very few instances in which I've watched a video on this machine I've used VLC, not mplayer, and these errors never appeared in these rare occasions that I used VLC.

• Question about metacity issue from previous post

  - by Alex Poulos

  Yesterday I had an issue with my 12.04 - 12.04 Does anyone know how to fix this? all of a sudden - my Terminal shortcut doesnt work and windows only appear in top left corner and some configuration causing an issue with metacity making it crash - I was walked through the problem, and found out that by creating another user account and logging onto it - the problem wasn't present anymore on that account but still was present on my old account. So my question is - was the problem just something in my old Home folder? - also - can most issues that occur like this be solved by making a new account and backing up the "Home" folder?
