Driver incompatibility(?) on Ubuntu 11.04

[pasoleatis]

One of my coworkers managed to get it working. The actual problem was a conflict between the NVIDIA driver and the Nouveau driver which apparently is preinstalled on Ubuntu. He managed to disable Nouveau - I’m not sure of the details of precisely how - and now it works.

This is pretty clearly a bug in the NVIDIA installer. It was run on a completely clean installation of the precise version of Ubuntu it’s advertised to work with, so there’s no legitimate reason for it to conflict with anything.

The Nouveau driver is very resilient. It has to be completely uninstall with the apt-get and some times also to have the modules blacklisted.

[font=“Arial Black”]Hi, giogovick helped me, I thank him. I found a guide that too helped me http://wiki.accelereyes.com/wiki/index.php/Installing_CUDA_Under_Ubuntu_10.04, in fact I added the following list in the file as suggested. But when I installed the driver NVIDIA the installation it conflicts with nouveau. The forums on the web suggest of disable nouveau as here. How disable nouveau by terminal (the console)??Help me!![/font]

Maybe this helps sudo apt-get --purge remove xserver-xorg-video-nouveau (BinaryDriverHowto/Nvidia - Community Help Wiki)

[b]Hi, I believe to have disabled nouveau because I installs successfully the driver Nvidia. But when I reboot the laptop the screen is black and appeared the following text:

starting restore sound card (s’) mixer state (s) fail

I resolves whit link [Risolto] [Audio] starting restore sound card (s') mixer state (s) fail • Forum Ubuntu-it

I reboot

and instead appeared the following test: PulseAudio configured for per-user session saned disable edit /etc/deflaut/saned

I resolved enable saned following the procedure by http://chiralsoftware.com/blog/Linux-network-scanning-with-saned-9404a25b8342ba4e.html

I reboot and appeared also *PulseAudio configured for per-user session, then X is not start. You have suggestions to solve this problem?Haven’t you this problem??[/b]

Well, the last post is quite old, so might be resolved, but just in case…

To know if nouveau is loaded do a

lsmod

.

I did have problems with nouveau on a fedora distro as well. Even blacklisted on modules.d and X11 driver removed, it would still be loaded on boot.

I solved the problem following the steps to change grub boot, as mentioned here, specially the part of setting the variable ‘vga’. Although, in my case, even with nouveau loaded X still worked with nvidia driver.

Hope it helps ane one with similar problems.
