This all originated when I installed Nvidia drivers from terminal using the xorg edgers PPA.  I have since uninstalled them, but that did not help much.  I can't even open terminal unless it is with ctrl+alt+f7.  I have tried forcing compizconfig to load from a similar question I found, but even after turning the unity plugin on nothing loaded.  Any ideas?

When I login, nothing happens.   I am presented with my desktop wallpaper.    No Dash, no Launcher, nothing.

Unity won't run on my new Ubuntu 11.04 install (with a Nvidia GeForce GO 7400). Ubuntu classic desktop works though, I tried all different drivers provided in the repositories.   Doing System → Administration → Additional Drivers gives me a warning :      This driver is activated but not currently in use.   I even tried the Nvidia driver from the official Homepage.  After some googling, I found the tool /usr/lib/nux/unity_support_test -p which tells me that my card is blacklisted. The other tests show a green yes.  Is this a bug? Or is my card too old which would be pretty surprising for me :P ?  Thanks.

I've just upgraded to Ubuntu 13.10 and I'm seeing a strange behaviour. All windows I open have a black, boxy border, including popups, as you can see in the provided image. (The black box in the bottom right is a terminal, which fails to display any text. However, I can enter commands and they execute.) I followed the steps in this post:  to reset Unity using the unity-tweak-tool. Although helpful, that did not fix the issue. I'm thinking this may be a graphics card driver issue.  Any help is much appreciated.

I have located where the error message originates from it is in  line number 221. As I have only a single nvidia driver installed I suspect it is is the same issue. I am not a developer but looking at the code preceding this line I can see the statement.  const char *glob_pattern = "/usr/lib/nvidia-[1-9][0-9][0-9]"  this will pick up nvidia-352/ nvidia-361/ and nvidia-361-prime/ ? on my PC.

I have a Samsung NP-QX411. It has two graphics cards, Intel and nVidia. The Intel drivers were quickly found and is fully functional. But nVidia, I have tried installing several drivers in different ways. But I can not run it without success. I do not understand how Ubuntu has by default the switch Hybrid Graphics option. What should I do?

I was installing ubuntu-Gnome 16.04 on my Asus ROG GL522VW laptop with an nvidia GTX 960m graphics card, and stumbled upon a problem.  After installation, I don't even get to the login screen. Instead my screen just freezes. I had this problem before, and got my answer in this post:   So I booted with nouveau.modeset=0, and everything boots just fine. But after I use additional drivers to install the NVIDIA binary driver - version 361.42 from nvidia-361 (proprietary, tested), I only get a black screen when I try to boot regardless of whether nouveau.modeset=0 is set or not.  While the screen is black, when I try to access the command line with ctrl + alt + f1 all I get is this: A start job is running for Hold until boot process finishes up (Xmin Xs/no limit) and no matter how much I will wait, it doesn't end and I have to reboot.  I followed the instructions in this post:   When I boot after reinstalling everything and choosing lightdm - it basically works but my login screen looks like a unity login screen, and when I insert my credentials it shows me a very bugged screen with all kinds of broken images with some of the things I had on my last boot, and after a few seconds my screen flashes on and off and it boots into my normal desktop, but still keeps spitting out system problem detected with only the option to close or report.  Also tried to install nvidia-355 and all kinds of versions, with no luck.  I wouldn't mind working with nouveau.modeset=0, but as far as I understand this disables my graphics card and doesn't utilize all of it's potential?  Any help or insight will be greatly appreciated. Sorry for the long post and if I should include more information please tell me what else I should include.  A huge thanks up front!  Edit: Reposted this question again and didn't know I can just edit the question to get it back up.  Edit2: Bumping again in a last effort to solve this issue  Please let me know if it is lacking information.

My Lenovo Z570 has two GPU's, nVidia and Intell. Brightness control has no effect what so ever over the screen brightness, and because I've had some major issues in the past when I was trying to fiddle with nVidia drivers and settings, and I wanna be cautious now. I haven't find similar questions referring 14.04 LTS with similar configuration as mine.   I've read that it could be fixed by adding/changing content in xorg.conf but when I run  sudo gedit /etc/X11/xorg.conf   the file comes out to be absolutely empty. What do I need to do, what do I need to add to it and not get my laptop screwed with a black screen again?

I recently installed 14.04.  But now I need a new driver for my nVidia GeForce GT 630. The former driver was rejected as not compatible with the 64-bit. I found that other driver and when I wanted to install it in the terminal with sh I was called first to stop the x-server. It cannot be installed with running x-server.  So how do I install them?

I recently installed Ubuntu. Everything was working just fine until I wanted to change the selected driver for my laptop (Lenovo Y50) under the Additional Drivers tab in settings.   I added the ppa: graphics-drivers software source and then I selected the latest available driver. I don't remember the version. Then I proceeded to restart my computer, but now it just gets stuck at a black screen with the message /dev/sda2: clean, 290961/14106624 files, 4246276/56401920 blocks.   I can't use the CTRL + ALT + F1 (or F2...etc) shortcut, literally nothing happens when I try.

Recently installed a clean version of Ubuntu 14.10 on my system. Previous to that, I'd been running Windows 7 with no problems.   My system has two screens, one of which is a LG Electronics 24EN43 which is hooked up to a GeForce GTX 650 via HDMI. This is the default screen. The second screen is a DELL 2009W connected to a GeForce 210 via VGA. My problem is that screen 2 does not seem to be behaving properly.   I can move my cursor right to the second screen, and my cursor becomes a black X with a white border. I can then move my cursor back left onto the first screen. I cannot move any windows to the second screen, and I cannot open any programs or terminals on the second screen. The second screen has a black background.   I am currently using the NVIDA X Server Settings utility, and under the 'Additional Drivers' section of Software &amp; Updates, I am using the NVIDIA binary driver - version 331.38 from nvidia331  Here is a haste-bin of my configuration file for the XServers.   Here's some other things I have noticed:   If under the Additional Drivers, I use 'X.Org X server - Nouveau display driver from xserver-xorg-video-noveau (open source). Then the second screen does work, it has Unity, background, and works like it should. However, the cursor on screen 1 has an annoying flicker, the computer will randomly freeze and crash, and it is really bad at watching videos (you see bars going down the video as it slowly refreshes at 0.5 frames per second)   If any additional information is required, I am happy to provide it. Many thanks

I've downloaded a driver for a video card (*.run) and tried to install within a terminal. When I started the installation process I got this error: ERROR: nvidia-installer must be run as root. I'm logged in with my own profile.

I try to find what graphics card I'm running, the commands in terminal only gives me this:   VGA compatible controller: Intel Corporation Atom Processor D4xx/D5xx/N4xx/N5xx Integrated Graphics Controller.    How do I install the correct driver? As I can see that not everything is displaying correctly. I want to set a proper resolution, but can't as I don't have the right drivers on my Ubuntu 12.04 machine. It's an Acer Aspire One netbook.

After installing Ubuntu 16.04, the Gnome Software Center was working.  I then started to have issues with it freezing.  I decided to uninstall it through the terminal, and then reinstall it through the terminal.  If I try to open the software through Unity, the icon opens, but after a time disappears.  If I type in gnome-software in the terminal, the command just hangs until I kill it.  I've tried uninstalling and reinstalling using various commands I've found on this forum and others, but nothing will successfully reinstall the software.  All other software seems to be working fine.  Can anyone help?  Thank you.

I have installed Ubuntu GNOME 15.10. I installed the nvidia tested proprietary driver and then I restarted. Afterr that I selected as primary GPU the Intel driver for normal use. However, when I enter a steam game(Portal) the graphics is bad so In order to play normal I have to switch manually to the nvidia driver again and reboot again. After the game I have to manually select as primary driver the Intel one and reboot again. It is so boring. QUESTION: How to automatically switch gpu graphics driver when I enter a game or something that needs more GPU?
