[Linux-fbdev-users] Atyfb: Screen garbled on Fujitsu FMV-253L

[Stephan D. <dr...@fr...>]

Hi list,
  I've just compiled Linux 2.6.20 on my Fujitsu FMV-253L with ATI Rage 
Mobility P/M.

Enabling the according framebuffer and giving the video=atyfb:... kernel 
option doesn't work properly, however.

With the panels native resolution of 1024x512, I can see that the screen is 
initialised properly (to the full resolution), but consists only of white 
on-pixel-wide vertical stripes. Some sort of blinking in the area of the 
curser is also visible.

Changing to other resolutions (640x480) didn't change much, same white 
stripes, but now with black borders left and right.

Changing timing information for atyfb (with M and R options in mode) didn't 
help, so did enabling the native panel interface in the kernel.

Funny thing is, that everything works fine in X.org with the ati/mach64 
driver, with a custom modeline.

Any ideas / patches, I might try out?

Thanks in advance,
  Stephan
