Question Ubuntu and Nvidia?


I have a PC that is dual booted with SuSe 11 and Ubuntu 8 with an Nvidia card and Dual Monitors. The SuSe 11 works just fine, however the Ubuntu, I can't seem to get working. I have tried everything I could find in the forums here and Ubuntu.

I got it to work for a little and was even able to use both monitors and set the setting in the Nvidia configuration program. Now, however, I can't even use that. Whether I enable the Nvidia graphics card through the hardware manager or not, the Nvidia Configuration program now says now card used and the res is about 500 X 400 or something like that.

Any Ideas how to fix this?

Code:
sudo dpkg-reconfigure -phigh xserver-xorg
when "he" will ask you for driver choose mesa

Have you tried simply replacing the xorg.conf Ubuntu generated with the one Suse provides? Don't delete the Ubuntu one, though, rename it and copy the one from Suse into that directory, then boot Ubuntu. If it fails you can always switch back. In any case you should compare both files side by side and see whether you can find important differences which may give you a hint.

I have no idea what this is about---what is the "mesa" driver?

If you meant "vesa", that is not a solution.

Are you using the nvidia proprietary driver on both systems?

On my system, lsmod shows an nvidia kernel module, but I don't immediately see what causes it to get loaded. Do "lsmod|grep nvidia" to see what you have.

PS: there is also an nvidia driver (in /usr/lib/xorg/modules/drivers/) I would assume that installing the nvidia package installs the driver ANd the kernel module.

do you mean xorg.conf? It should have an entry similar to this:
Code:
Section "Device"
    Identifier  "My Video Card"
    Driver      "nvidia"
EndSection
This typically has to be changed manually after installing the nvidia driver.

Forget the Nvidia config tool for now.

Do you have these files?
/usr/lib/xorg/modules/drivers/nvidia_drv.so
/lib/modules/`uname -r`/kernel/drivers/video/nvidia.ko **

You said earlier that lsmod showed the kernel module. If all this is in place, then things should be working. When you start up X-Windows, what exactly happens? (Note that after adding nvidia to xorg.conf, you would have to re-start X (ctrl-alt-backspace) for it to take effect.

** Note that uname -r is in backtics, not single quotes

For the second file, look in the path I stated to see if it is there---hard to see how lsmod would be able to show it if it's not present..... As for the xorg driver, it sounds like you need to start over and install the nvidia package. (Is it available in the Ubuntu package manager?---If not, I have had good luck with the official Nvidia installer (at their web site.)
