• Broken Gnome panel after Ubuntu Update

  - by Asaf

  Like every single update on Ubuntu system, my graphical system is completely broken after updating to version 11.10 http://i.imgur.com/YIHfA.png As shown in the image, the date is in the middle of the panel, There are many icons missing (network connection icon, skype) There's no right click menu when I try to right click on the panel and many programs don't have their menus (file,edit,view... those things). How do I fix this? I have gnome-panel, I don't want Unity and I'd rather install windows 95 before I switch to it.

• Games installed from repos won't start

  - by Shauna

  I'm running Natty (upgraded from Maverick) with Gnome 3 (from the Gnome 3 PPA, Unity removed), and have recently found that some of my games from the repos no longer work. When I go to start them, I get the message Failed to launch [app name]. Failed to execute child process [app name] (no such file or directory). I've so far found this on Gweled and PyScrabble. Other games (Mines, Sudoku, Mahjongg), as well as other applications have opened just fine. Gweled used to open fine until recently. Any ideas on how to fix this?

• How to configure Thunderbird to notify new mails only in certain folders?

  - by Karthik

  I have Ubuntu 12.04 and recently started using Thunderbird. I have GMail account and have configured a lot of Labels in it, all of which appear as folders in Thunderbird. Most of these are just subscriptions to mailing lists and are not that important. I have a few labels which are very important, for whom I would like immediate notification when a mail arrives. The problem is that the Mail indicator in the Unity top Panel, lights up for any incoming mail. How do I configure it to indicate incoming mails only in certain folders?

• Ubuntu freezes/crash after wake when upgraded to 13.10

  - by krustbr

  Back on 13.04 it didn't occurred. I've upgraded to 13.10, systems apparently working fine, but, when I put it to sleep(using or not using extended monitor) and try to wake up, I see the screen(both), without lock-screen, but completely freeze, Neither tty open, nor the keyboard works. So, only option remains is to force shut-down. Any clue how to investigate the cause or fix it? Thanks in advance, any info that'll help you could ask! Ubuntu 13.10 x64 - not a fresh install/upgraded - with Unity Dell Vostro 3550 AMD Proprietary Drivers - 13.11 / Hybrid with Intel

• How to reset the Xorg / xserver?

  - by thomas

  xserver keeps crashing on my general user account both in unity 3d and 2d. It doesn't do it on the guest account. That's why I want to reset / rollback everything xserver related, hoping this is going to fix it. Most answers on this involve sudo dpkg-reconfigure xserver-xorg. However, this does nothing for me (generates no output) and I read in other forums, that it's deprecated. So, what's the current way to reset all xserver / xorg options; what's the alternative to sudo dpkg-reconfigure xserver-xorg ? Thanks Edit: X crashes during work, not before login or so. And the effect of a crash is, that I get thrown out of the session, not a freeze or machine crash.

• deactivate dynamic contrast on dell xps

  - by Rock

  I am experiencing annoying automatic backlight brightness changes under ubuntu 12.04 LTS on my Dell XPS ultrabook. It seems to be connected to the amount of white pixels on the screen (switching back an forth between dark/light application windows makes the effect noticable, but also just scrolling through a website.) So I think it is the dynamic contrast feature of the notebook screen. How do I turn this off in Ubuntu? Windows offers specific Intel driver options for this, but I can't find any for Ubuntu. EDIT: Model: Dell XPS 14 Ultrabook and currently running Unity

• Unable to install Nvidia drivers

  - by Tazzer

  a few days ago I installed ubuntu 11.10 on my friends computer. Despite all of our efforts we are unable to open the default unity and it will only open the 2d interface. I have been told in the IRC chat room that we need to install the graphics card drivers(nvidia geforce 420.) When I check the additional drivers app it doesn't show any to install. I tried installing the ones from the nvidia website but no luck, I also forgot to mention. I don't know if it means anything but he has a 64 bit computer and it is ubuntu 11.10 64bit.

• Fastest bit-blit in C# ?

  - by AttackingHobo

  I know there is Unity, and XNA that both use C#, but I am don't know what else I could use. The reason I say C# is that the syntax and style is similar to AS3, which I am familiar with, and I want to choose the correct framework to start learning with. What should I use to be able to do the most possible bit-blit(direct pixel copy) objects per frame. EDIT: I should not need to add this, but I am looking for the most possible amount of objects per frame because I am making a few Bullet-Hell SHMUPS. I need thousands and thousands of bullets, particles, and hundreds of enemies on the screen at once. I am looking for a solution to do as many bit-blit operations per frame, I am not looking for a general purpose engine. EDIT2: I want bit-blitting because I do not want to exclude people who have lower end video cards but a fast processor from playing my games.

• One click access to bookmarked files?

  - by dunderhead

  On my Windows machine with just one click I can launch favourite or bookmarked files that I use on a daily basis, which is a great time-saver. Is there any way to do this with 11.10 Unity? Ideally I would like to right-click on an icon in the launcher and have a list of files appear that I could then left-click to launch, but I'd be happy for any simple solution. Please note that I am not referring to recently used files lists - these do not work at all because the bookmarked file will always drop off the bottom of any recently used file list.

• Project Hamster notifications missing on upgrade to 12.04

  - by deshmukh

  I have upgraded from an almost default 11.10 install to 12.04. All went well and I can login, logout, etc. without any problem. One very interesting thing about the Project Hamster notifications, though. I have set Hamster to remind after every 27 mins. I do not get these notifications. However, if there is no activity set, I see the notification. In 11.10, I used to get both the notifications. What is wrong? How do I set it right? By the way, the notifications work quite well in Unity. But in Gnome, the problem continues.

• Can not get to login screen, background starts with terminal prompt only

  - by Doug

  my uncle has Ubuntu on his work PC. Basically I came in to work today, and he had lost his UNITY side bar. I told him start with just rebooting it. He rebooted it... now it does not even get to the login screen. It gets to the background with the word UBUNTU, and the 6 or 7 dots, does it's little loading dot thing... then stops, and a black terminal opens on the top left with the background still in place. Personally, I think he screwed it up himself. He always swears he didn't touch anything, but I know better... Either way, I can't get him back into the desktop to even see if the sidebar is back. He's always screwing around pressing the wrong buttons on the login screen, hitting admin things and such... Any ideas?

• Ubuntu 12.4 cursor changes

  - by mantic0

  I have a weird problem with my Ubuntu 12.4 dual screen setup (Toshiba laptop + one monitor). After a while the cursor on one screen completely changes its shape (not every time). I don't really know how to describe it because it's always something else. Sometimes I get four or five vertical lines instead of a cursor, sometimes I can only see part of the cursor, etc, sometimes weird shade appears. This only happens on one screen simultaneously. If I go to the other screen, the cursor appears to be fine but when I change screens, the cursor changes. I tried to do a screenshot but when I do, the cursor looks just fine. I'm using Unity and Gnome 3 but the problem is on both desktop environments. Nothing is wrong with my screen though because I'm also using Windows and I don't have any problems there.

• Artist, Looking to lean how to program games, where do I start? [on hold]

  - by Christopher Hindson

  I have bean an artist for many years now I am very comfortable with using Photoshop and Flash but I want to learn how to but together my own games, I bean doing my own research into this and at the moment I am at little bit stuck on witch direction to go down. So my question is witch programming language should I learn? I have already bean looking into this what i understand is that Gamemaker with its built in language (GML) is one of the most friendly to people who are new to the game making world. I have played around with this program and was pretty happy with it but I want more also you can use Unity with language such as C and javascript and then games built with Java witch looks interesting. One more thing before you send your answer in at this moment in time I would only be able to make 2D game but 3D isn't out of the picture.

• window borders, menu bar missing over VNC

  - by zacaj

  I'm running Ubuntu 14.04 with Unity and Gnome3, however I don't have a screen hooked up anymore. I have installed x11vnc and run it with "-create" so that it will create a new X11 session, however when I VNC to it, the menu bar, window borders, etc are missing, windows are ordered based on creation time, and cannot be resized. Now, I don't really care if I end up with Ubuntu or Gnome's window manager, as long as this doesn't mess up my normal desktop stuff if I should happen to hook a monitor up again, and I'm not even attached to x11vnc if someone can point me to a good complete tutorial using something else, but I've been trying vino and tightvnc and rdp and x11vnc is the only one I've managed to get this far.

• Volume setting isn't remembered after restart/shutdown

  - by Iulian

  This is my first time here and I'm new to linux and also to Ubuntu. I've installed first version 11.10 and there was some problems with the unity dock and also the problem with the volume not being remembered after restart or shutdown. I'm using dualboot with Windows 7. Ubuntu was installed after windows. I have 2 sound cards. One is onboard, on the motherboard, and the other is external, an E-MU 0404 USB 2.0 sound card. The last one is my primary sound card and I've choosed it as default output sound card. I've upgraded to 12.04 hopeing that this was fiex but even in this version the OS doesn't keep the volume where it was last time. The big problem is that sometimes I forget about this problem and start music and it starts at full volume and soon I think I will die of heart attack. Is there a way to make it remember or at least to tell him to start at a specific volume not at 100%?

• ubuntu 12.04 ambiance dark side bar issue when clicking folder on desktop

  - by Lou Crittenden

  ubuntu 12.04 gnome: concerning an updated custom ambiance theme: why is there no dark side bar when I click on a folder, like the home folder icon on the desktop, but the theme works as planned when I type "nautilus" in the terminal to open the home folder or when opening a folder up as root? Permissions issue perhaps? note: i am using cinnamon instead of unity and i noticed it uses the nemo file manager instead of nautilus and i suspected that it was causing me the grief. so i uninstalled it and now am using nautilus only as the file manager. i found this out when i typed: "sudo killall nemo" and the problem went away. i'll see how this goes... (and hopefully cinnamon doesn't care about it...) has anyone else had any issues with this?

• Cannot sleep/standby in Ubuntu 12.04

  - by mstaessen

  Yesterday, I installed Ubuntu 12.04 Desktop i386 on my netbook (HP Mini 311c). I am unable to use the sleep mode. When I press the suspend button (or do sudo pm-suspend), the screen flickers but the computer does not power off. Even worse, the screen comes back up and I'm back where I left off. Hibernating does work (although it is not available in Power Management). I have to use pm-hibernate to make that work. I'm using the 3.2.0.20 kernel and Gnome 3.3.92 (Unity, especially compiz, is a resource hog). Before Ubuntu 12.04, I was using Mint Linux 12 with the 3.0 kernel and everything worked fine back then. Any help is much appreciated because this is driving me crazy.

• Why are KDE components being installed/updated on 12.04 with GNOME?

  - by Dune

  I am not yet fully versed with the components installed by default on my machine, so I will apologize in advance if my question is silly. shows that a lot many of (what I assume are) KDE components (libk*, kde*, etc.) are being installed/updated on my machine. That is just the output from sudo apt-fast update && sudo apt-fast dist-upgrade -y from a few minutes ago. Can anyone tell me why? Can I safely remove them? If yes, how? Thanks in advance for any replies. System specs: Fully updated Ubuntu 12.04 x86_64 w/kernel3.4, Gnome, Unity, Core2Duo, 4GB

• Very High CPU usage (100%) from just browsing the Web

  - by cole

  I tested on Firefox and Chromioum. Im at 100% while loading pages which causes them to load slow and when I dont have a application running Im at 40% CPU (At least) Everything is slow basically. Im also already on Ubuntu Classic so im not using Unity. Should I go to 10.04? is that more stable? On windows this wasnt an issue. I have a Dual Boot with XP and a 2.4Ghz Intel Celeron with 768MB RAM and an Nvidia 6200 Graphics card. I heard 10.04 was the most stable. any suggestions?

• Best way to find freelance c# developer

  - by sturdytree

  I am a developer based in London developing a desktop WPF business application using c# (+ MVVM/DDD/Nhibernate/Unity/Postsharp...). I need to find someone to review my code to suggest improvements and then to write integration tests. This could potentially be an ongoing relationship, expanding into writing new features etc. It would suit an experienced developer with a strong interest in design principles and writing clean code, who can work part time. However, the developer would need to work at my home based office (although timing is flexible). Websites such as elance and odesk seem to tie you in, and I would prefer to pay a one off introduction fee and then deal with the developer direct. Stack exchange seems quite expensive but is a possibility if I don't find an alternative. So, are there any other websites I can try?

• What are my tool options to prototype a 2D online multiplayer game?

  - by Asher Einhorn

  I'm looking for the best tool to allow me to quickly put together a 2D game that relies largely on networking. It's extremely likely that this game will require a server side program to constantly run. I have little experience with these things and since it's a prototype i'd like the easiest options for achieving this. I am looking to make this game for the web and mobile devices, although at present I only have access to ios hardware, (no android etc). I just want to get the bare bones of this set up so I can test it from the earliest opportunity to see if it's fun. EDIT - doesn't unity have some inbuilt networking stuff in it?

• System Settings icons missing

  - by pst007x

  Is there any way to reset the System Settings Control Panel page? The Control Panel was fine, but the for no apparent reason, PRIVACY, BACKGROUND and a host of other icons have vanished... My system seems pretty messed up after the upgrade... Shutdown, Reset, and Logout from the menu no longer work either... However, I can launch the Privacy panel from the terminal: activity-log-manager and it runs... so why is this, and others, now missing from the System Setting Control Panel? I have checked and: activity-log-manager-control-center is installed Is there a config file I can check, or a setting in Gconf where the list of icons are referenced? I have run - in desperation - sudo apt-get purge unity* sudo apt-get purge ubuntu* sudo apt-get autoremove Run Gconf-cleaner and Janitor then re-installed all packages Still the same issue....?

• Ubuntu boots into tty1 after driver downgrade

  - by Zach

  Earlier today I downgraded the driver for my nvidia 240 GT from version 310 to version 304 using ubuntus "additional drivers" utility. After the install I rebooted but instead of opening unity and allowing me to login it booted into tty1 instead. After using the "startx" command I got the message, "nvidia: API mismatch: the nvidia kernel module has version 310.14, but this nvidia driver component has version 304.43." What can I do to solve this? Edit: Solved my own problem by purging all nvidia packaged and reinstalling my drivers.

• Ubuntu 12.04. Compiz Failure. Computer has nothing to use

  - by Teddy

  I updated to Ubuntu 12.04 with Compiz..now Compiz is failing and I have no tool bars or ways of getting to applications except for firefox from a link presented from sending an error report. How am I supposed to: Fix this mess with no navigation to get to the terminal, or software center. When will this problem be fixed? When I updated the system why didn't it change me back to the crappy Unity interface (No offense). If it can't be fixed how do I get my files back?
