I experience something similar on my notebook.
- AMD Turion CPU; 3GiB RAM; nVidia GeForce Go 6100 video controller
- was working fine with 64 bit Ubuntu 10.04 using nv X video driver
- problems on 64 bit Ubuntu 12.04 with nouveau driver (VESA driver works but
does not support native resolution)
Symptoms are various. Simplest, on fully updated system: LightDM seems to work
to allow login but Unity desktop does not show up except for background.
dmesg shows a lot of messages like this (and variants):
[drm] nouveau 0000:00:05.0: PFIFO_DMA_PUSHER - Ch 3 Get 0x01256038 Put
0x011c60b0 State 0x4ffe0004 (err: INVALID_MTHD) Push 0x00000000
/var/log/Xorg.0.log shows lots of mayhem after this message:
[mi] EQ overflowing. Additional events will be discarded until existing
events are processed.
Adding mem=2g to kernel seems to fix the problem!
Thanks Salah for this discovery! Thanks xexaxo on #nouveau for recognizing my
problem and pointing me here!
I will attach logs.
