I just installed Ubuntu 9.04 on my desktop alongside Windows XP, Windows 2000, and openSUSE 11.1. The first time I logged into Ubuntu, I was given the option automatically to install the best nVIDIA driver for my display, but after doing so and rebooting, I found that my screen resolution was stuck at a horrendous 800x600. I was luckily (lol) given the option of using an even lower resolution though. Anyway, I searched the Net for people with similar problems and how they resolved them, trying to be as hands-on as I could. I tried editing my /etc/X11/xorg.conf file but when I rebooted I got the following message: Code: Ubuntu is running in low-graphics mode The following error was encountered. You may need to update your configuration to solve this. (EE) Unable to find a valid framebuffer device (EE) NV(0): Failed to open framebuffer device, consult warnings and/or errors above for possible reasons (EE) Screen(s) found, but none have a usable configuration After uninstalling the nVidia drivers I downloaded, I rebooted but am still left with the same message above. When I click [OK] I am forced to "Run Ubuntu in low-graphics mode for just one session" as "Reconfigure graphics" doesn't take care of anything. My monitor is a digital TV/monitor that is probably not too well known called the APEX LD 1919 (19 inch) and my video card is the nVIDIA GeForce FX 5500. I'm at a total loss for what to do and it's driving me crazy. I've loved my time using a working Ubuntu desktop, but unless I can fix this I probably will have to leave the OS. I'd appreciate any assistance greatly. Anyone have any ideas?
install the nvidia binary driver hit alt-f2 to bring up the run dialog "gksu nvidia-settings" make sure you save the changes to xorg.conf also --2x 20" LCD's on a geforce 6800.
Thanks. But unfortunately, when I get into the NVIDIA X Server Settings window, I have only three Resolution options: "auto" (which is 640x480), "640x480", and "320x240". It's so bad that the word "System" is cut off in the top panel...
hm, did it work fine with the livecd? i had a ati 8500dv agp force me into low-graphics mode, not sure how i got around that. i'd update my install, or try a older ubuntu disk-- the graphics detection/setup utility that is used now is new. ubuntu-tweak has a option to enable some more updated x/driver repositories. that might help also.
Yeah, with the liveCD it was fine as far as I can recall. Well, actually, part of the installation window was cut off when I installed from the liveCD so maybe not. I'm not really sure. Well, I had a similar problem when I installed Ubuntu 8.04.
I. Hate. Binary drivers. You've uninstalled the drivers, right? Well, it sounds like you've made some changes to your xorg.conf that it doesn't like, and it doesn't sound like you've changed them back. So try to roll back your changes. I would use the following command to do that via the terminal (which you can force it to drop down to when it boots up, if it doesn't already, via hitting ctrl-alt-f1): Nano's just a handy uncomplicated text-editor. The interface should be self-explanatory as long as you know that the ^ symbol is shorthand for the control key, ie ^C means control-C. Or, you could just throw your xorg.conf file out the window. It's not always necessary; the x.org guys are working like dogs to make hardware autodetection good enough that you don't need a xorg.conf. You didn't have one on the LiveCD. Just rename it to something else and try rebooting. Basically, if whatever driver it defaults to drives your desktop well enough, I would be happy with that. Working with NVIDIA's drivers is like living with an abusive spouse. I've wrangled and I've wrassled with NVIDIA's drivers for years now, and they are a ROYAL PAIN if they decide they don't like you.
