Binary package hint: xserver-xorg-video-nouveau
Expectation: Default Xorg driver should work with no video artifacts.
Observation: Bad screen flicker with default Xorg driver.
Details: I installed the 10.04 beta from CD on Wednesday (incidentially,
compliments for the smooth install). Already upon installation, the
display did flicker badly whenever the CD was read or even the mouse
moved. Flicker did already start at the initial splash screen. The
system was fully responsive otherwise. On reboot post-installation, gdm
came up OK but with the same flicker problems. The 'Monitors' control
panel only offered the 2048x1536 resolution at 80 Hz with no other
options. Tried to install and use one of the non-free nvidia drivers,
this failed because the nouveau kernel module was loaded always and
could not be unloaded (drm loads nouveau before framebuffer console
init. as near as I can make out). With nvidia-current unable to load,
the X server could not use the 'nvidia' driver. Switching xorg.conf to
use the 'nv' driver results in a much better screen display (only
occasional flicker) although the driver only supports 2048x1536 at 60
Hz. 1600x1200@85 Hz is useable.
