I have a Dell Inspiron 910 and am receiving a running in low graphics mode error.  I believe the error was caused by attempting to install a game I did not have the proper space for. I have tried a few of the fixes described in previous posts but have had no luck. I get messages that I have zero space remaining.

Note: This is an attempt to create a canonical question that covers all instances of &quot;low-graphics mode&quot; error that occurs to a user, including but not limited to installation of wrong drivers, incorrect or invalid lightdm greeters, low disk space, incorrect installation of graphics card like ATI and Nvidia, incorrect configuration of xorg.conf file while setting up multiple monitors among others. If you are experiencing the &quot;low-graphics mode&quot; error when trying to login but none of the following answers work for you, please do ask a new question and then update the answers of this canonical question as and when your new question gets answered.   When I try to boot into my computer, I am getting this error:  The system is running in low-graphics mode Your screen, graphics cards, and input device settings could not be detected correctly. You will need to configure these yourself.   How do I fix the failsafe X mode and login into my computer?  Answer index:

I have opened up  on launchpad too, but in the interest of getting a bigger response base I am posting it here, hoping someone will pick it up.  Natty doesn't behave very well with the Intel 82845GL chipset. I booted my old machine with Natty today to test drive it. The specs are:  Processor: Celeron 2.4GHz Video: Intel 845GL RAM: 1GB  The first problem is that the display is borked! What do I mean? Well, see for yourself:     If that gets fixed (and it did for a while but is back now), Unity is disabled.   I think these issues are owed to hardware acceleration being disabled...or in other words not the right driver for my hardware. A google search on 'intel 82845GL ubuntu' does return other users having similar problems in the past but I haven't been able to pick out a solution in the many many discussions on the subject- partly owed to my 'linux naivety' I guess...but maybe you can help?

I have a Dell XPS 15-9560 laptop with 15.6" 4K Ultra HD (3840 x 2160) IGZO IPS 350-nits Touch-screen, and NVIDIA GeForce GTX1050 4GB GDDR5. It's having 4K resolution. Right from the grub screen to Ubuntu, it's having very very small fonts. Is there any way i can increase the fonts size?  This is a real nice laptop - real MacBook Pro killer..getting very popular...and i can see a lot of folks will be having the same issue.  Edit 1  I messed up my current installation of ubuntu desktop 18.04 LTS and have to reinstall it all over again. Just tried this one now: Adding nouveau.modeset=0 to the boot parameters was much better workaround for smaller fonts and i am having much better resolution now. It's much better solution than others as of now.  Seems to ubuntu18.04 LTS is not as stable and much more complex issues with Nvidia graphics card than the previous versions.

I am considering trying to setup a  system. It seems like this would be pretty straight forward if I had two graphics cards or if I didn't need hardware based OpenGL acceleration. Is it possible to setup a multi seat system with only a single dual-headed graphics card?

My GTX 960 is reporting there there is not enough memory, even when another person the same card is able to render it fine. The other person had the same set up as I do and rendered the same scenes. He did not have this issue.   I'm a render farmer for black plasma studios and I have come across this problem with my rendering recently. I was doing a benchmark test for them and blender gave the error (in the title).  My first test went good:    But I got the error on my second test:   as you can see it renders the first square but then runs out of memory after that. It did not render at all until I updated my graphics drivers with GeForce Experience. This helped a little but the render still didn't finish.  I seem to get this error a lot now and I would assume a better graphics card would be needed but someone else in the group has the same one that I have and he can do it just fine.  Computer info:  Display Device: name: NVIDIA GeForce GTX 960 DAC type: Integrated RAMDAC Device Type: Full Display Device Approx Memory: 6091 MB    System: OS: Windows 10 Home 64-bit processor: Intel Core i5-6600K CPU @ 3.50GHz (4 CPUs), about 3.5GHz Current Display Mode: 1920 x 1080 (32 bit) (60Hz) Memory: 8148MB RAM  How do I fix this?

I have a Dell N5110 laptop with integrated Nvidia GeForce GT 525M and an Intel HD Graphics 3000 card; My problem is the default card is the Intel one, and it provides a very bad performance with Windows 8. So can I force to use the Nvidia one all the time including "Desktop Windows Manager" ?

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 want to enable GPU rendering, but there is no option in User Preferences > System:    Why is this? How can I get cycles to render using my GPU?

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.

I want to test the memory of my video card because there are vertical lines on my screen. I have done some basic troubleshooting and it seems that the problem is in the video card. I want to validate that the issue is the video card by testing its memrory. I have found software that is used for Nvidia cards with CUDA support, but my card is the Nvidia GeForce 7600, which has no CUDA support.

Initially, the computer was showing the error as mentioned in   question. Fixing it resulted in the above error.  Please take look at the last line   Started GNOME display manager... and deal with any system changes..p link was shut down.....     One more thing before all this problem I have edited xorg.conf file to use  as suggested on .  I don't know if that's the reason but I thought it is important to share.

Just bought a Geforce GTX 660 and replaced my Radeon HD 5870 (it finally died after 3 years). I'm having terrible problems getting the video card to work. As I only had command line options so far I've ran:  (purged fglrx*)  then  sudo add-apt-repository ppa:xorg-edgers/ppa sudo apt-get update sudo apt-get install nvidia-331  and then I started getting low graphics mode errors. did some searching on my tablet, and I tried several things but what finally worked better was:   sudo apt-get install bumblebee bumblebee-nvidia  However now that I'm logged into my computer finally, I have no access to terminal, no access to the top bar, and hitting Super Key does nothing, alt-f2 does nothing, and I only can post because I tried running WoW and it had an error and the error report opened a link.   All I can see on my desktop is my wallpaper and desktop icons. I can CTRL+ALT+F1, and navigate to the downloaded official nvidia driver, however that won't run because of x-server, and I can't run it from my desktop.   Can anyone help me?

I have GeForce GTX 560 Ti. I's worked fine in 12.04 with nvidia drivers. Unfortunately, after todays 12.10 update, something broke down.   I've tried nvidia-current, nvidia-current-updates and nvidia-experimantal. Always the same behaviour: Bad resolution in lightdm, after logging nothing except wallpaper. No unity panels, "win" key doesn't work.   After removing nvidia drivers everything work.

I am trying to install Ubuntu 11.10 on a Dell OPTIPLEX 3010 IvyBridge and when I start the setup, the screen goes awry with a lot of colored patterns.  Is there a way to start the installer in text mode or a graphical safe-mode?  On Ubuntu 11.04, it works well.
