running Ubuntu 11.10 and after updating video driver it stops loading after (fail) on LightDM display manager. I can get to the command prompt but don't know any of the commands. I've been reading and tried a few things, but nothing has worked. This has happened twice. The first time I just gave up and reloaded Ubuntu.

I am very new to Ubuntu.

My system is an old socket 754 AMD system I built that still uses AGP for video. My video card is a 6600GT. I have a gig of memory. The mother board is a Gigabyte K8ns. Every thing was running great till I tried to use the nvidia driver.

I went to Nvidia's site later on a different computer and downloaded the driver it called for. How do you install it or is there an easier way?

been fighting the NVIDIA drivers myself....

I tried to install an NVIDIA driver, and it bailed on me -- Hung before beginning lightDM. Luckily, it should back up your xorg.conf automatically, which is what causes the problem. When it boots and begins to hang, do control+alt+f1 to make a terminal. If you tried to isntall an NVIDIA driver from their site and after running, it would not start LightDM, Login and run the following two commands.

sudo rm /etc/X11/xorg.conf

sudo mv /etc/X11/xorg.conf.backup /etc/X11/xorg.conf

Hope this helps!

All I got was (No such file or directory). I didn't install the drivers from the Nvidia site. I couldn't figure out how to install it. – Eric Oct 17 '11 at 3:51
Alright, if its not from Nvidia, there will be no backup file. Try perhaps installing nouveau drivers with apt-get install? (sudo apt-get install nouveau-firmware I think) – Wane5tars Oct 17 '11 at 7:31
Thank you for the help. I gave up and reloaded Ubuntu and will do some reading before I try to update the driver again. I gotta learn how to fix things if I'm going to run Ubuntu. – Eric Oct 17 '11 at 19:46
I feel your pain. This is the 5th install in 2 days. – Wane5tars Oct 19 '11 at 13:57
