Ubuntu

Graphics glitch - Lucid + Nvidia + latest drivers

Asked by Ross

Please see screenshot of problem to better aid my description:

This has happened on multiple programs including terminal, firefox and wireshark. It seams to effect only one program at a time.
My system:
-Ubuntu Lucid 64 bit + latest updates
-kernel 2.6.32-22-generic
-GNOME 2.30.0
-Intel C2D 3GHz
-4 GB RAM
-Nvidia 8800 GTS

I have tried the 'Hardware Driver' program to download Ubuntu's latest Nvidia driver, however this does not solve it. I have also downloaded the latest driver direct from Nvidia (NVIDIA UNIX x86_64 Kernel Module 195.36.24 Thu Apr 22 19:10:14 PDT 2010). This does not solve the problem either.

A separate issue which might be related is the startup resolution is very low (after grub and before login screen). I can't change this and have tried adding 'vga=...' to the kernal startup options in grub.

Is this a problem with Nvidia, has anyone else had this problem?

Thanks
Ross

This has solved the problem with the boot resolution, which I am thankful. I have not had the 'glitch' probem yet as shown in the image link above. Hopefully it would have fixed both!

Does the 'framebuffer' option slow anything down, or is it only in effect at boot time?

Sorry, I still get the glitch as shown in :

http://dl.dropbox.com/u/6743276/Screenshot.png

the above help only solved the boot resolution problem. I still get the the graphics glitch as outlined in the original post.

will fix the boot res. Seem like just that app is bad as the surrounding is ok.

No fix to this problem

This bug would make itself apparent on different programs randomly.

Since then I've had Ubuntu completely loose my Nvidia drivers, probably because of an update. However Nvidia have updated its drivers, so this problem hopefully will magically go away.

I have turned off all fancy effects in Gnome and disabled 3D wherever I can.
