Public bug reported:
Binary package hint: xserver-xorg-video-nouveau
System:
Description: Ubuntu lucid (development branch)
Release: 10.04 (beta 1)
Package:
xserver-xorg-video-nouveau 1:0.0.15+git20100219+9b4118d-0ubuntu4 (or
one of its kernel module dependencies)
Maybe related: #425372
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. 1600x1...@85 Hz is useable.
The main board is a dual Athlon X2 AMD M2N68-AM Plus with onboard nVidia
graphics chipset.
I append partial dmesg and lspci output. If there is any other
information that could be of help, let me know.
