According to http://www.nvidia.com/page/geforce2go.html there were 16, 32 and 64 MB versions of GeForce2 Go. Very similar bug was reported few months ago: http://lists.freedesktop.org/archives/nouveau/2011-July/008631.html Can you test patch (hack) posted there?> I can also get it to work using "NoAccel", including at full 1600x1200, > depth 24, although obviously with fbdev-like performance.Note: that's almost half of your VRAM.

https://bugs.freedesktop.org/show_bug.cgi?id=42384 --- Comment #5 from Chris Paulson-Ellis <chris at edesix.com> 2011-10-30 09:06:24 PDT --- You're absolutely right. The VRAM is 16Mb. I was misled by the GART aperture being 64Mb. No need for the hack. I managed to get it working by setting the framebuffer to 8bpp at the lowest resolution listed in the modelines from the Xorg log (640x350). I can then get X working at full resolution as long as I use 16bpp. These together account for <4Mb, so something is being profligate with the VRAM, but it works, so I'm happy. Thankyou for your help. For the record, I put the following on the end of the kernel line in grub.conf: video=LVDS-1:640x350-8 and my xorg.conf looks like this: Section "Device" Identifier "n" Driver "nouveau" EndSection Section "Screen" Identifier "n" Device "n" DefaultDepth 16 SubSection "Display" Depth 16 Modes "1600x1200" EndSubSection EndSection I'll attach new logs. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.
