Description Oswald Buddenhagen 2007-10-07 02:38:08 UTC 
this is one of the "peripheral" issues mentioned in bug #10754 (please look there for the complete log and config).

after some video mode switches the graphics mode (but not the text mode) produces no color signals any more (but still correct timings).
InitPrimary does not help, i have to reboot.

diff-ing the logs gives:
--- Xorg.0.log.good
+++ Xorg.0.log.bad

Oswald, Can you still reproduce this issue now with 2.2.0 driver? would you please attach a picture to help us understand the situation? thanks!
Comment 2 Oswald Buddenhagen 2008-01-08 00:08:51 UTC 
picture? imagine a black screen ... :-D
anyway, i can't reproduce it any more (note that i'm running git master, not 2.2).
Comment 3 Michael Fu 2008-01-08 17:35:37 UTC 
I see. I was just thinking you probably means more with " no color signals any more (but still correct timings)." :D Anyway, thanks!
