[Ubuntu-x-swat] [Bug 549256] [NEW] [GeForce 7025 / nForce 630a] video flicker on any I/O activity with nouveau; OK with nv driver
You have been subscribed to a public bug: 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.
