9400m poor performance

pegler · 06-24-09, 01:35 AM

I recently built a machine and used zotac's itx-b motherboard. It says it has an onboard 9400M GPU. I am running Ubuntu 9.04. I installed the 185.18.14 driver as recommended from places I read. I restarted and now I have worse resolution than before. I can only select between 640x480 and 320x240. Any advise would be greatly appreciated.

Thanks,
Matt

My advice is to get rid of the manually installed drivers and use this repo instead :

Code:

deb http://ppa.launchpad.net/thefirstm/ppa/ubuntu jaunty main

Installing the drivers manually is just asking for trouble IMO. Ofcourse you couldn't possible have know.

Although from the log it does seem that it doesn't detect the CRT monitor correct.

Have you tried looking in the 'nvidia-settings' application?

I looked into the nvidia-settings application and didn't find anything that would let me specify my display, or force any sort of setting. Did I miss something or is there a command I can run from the command line to force a setting?

Thank for your quick response.

Nothing under "X Server Display Configuration"?

Yes, you can force a monitor setup in xorg.conf if you know the horizontal and vertical Hz. Don't remember what the settings are called, but I remember it being described in Nvidia's README file.

That worked. I ended up following the instructions here: http://ubuntuforums.org/showthread.p...379#post129379

Thanks for your help!

Glad I could help. Do also check up on using the ppa instead of manually installed driver. You'll thank yourself when the kernel gets updated.
