Description Tavian Barnes 2009-07-14 08:24:41 UTC
I have a 9800M video card in my laptop, and have been using the nouveau driver for a while.  Recently I upgraded to a git kernel + DRM module, to test out KMS.  It seems to work fine when X is running, but if X isn't running the display is simply blacked out.
Comment 1 Chí-Thanh Christopher Nguyễn 2009-07-14 09:24:10 UTC
This is more often than not caused by disabled FRAMEBUFFER_CONSOLE in the kernel or (if built as module) fbcon not loaded.
Comment 2 Tavian Barnes 2009-07-14 09:58:54 UTC
Nope, my kernel is compiled with CONFIG_FRAMEBUFFER_CONSOLE=y.
Comment 3 Pekka Paalanen 2009-07-14 10:15:02 UTC
The standard procedure: please provide kernel and X logs.
Comment 4 Tavian Barnes 2009-07-17 09:02:41 UTC
Never mind, it turns out uvesafb was running.  I didn't expect it to run without a "video=uvesafb:..." option on the command line, but it does anyway.
