Description WuNian 2007-11-14 19:13:49 UTC
If kill X then restart it, X can not start up and driver reports:

(EE) intel(0): No valid modes.
(EE) Screen(s) found, but none have a usable configuration.

We found it Q965, GM965. This bug is not stable. It may occur sometimes.

We use today's tip.(11/14/2007)

No special config on xorg.conf. We use EXA.

xorg.conf pls? And what's your versions?

I can't see this on my t61.

dup of bug# 11598?
Comment 6 WuNian 2007-11-20 22:47:13 UTC
It seems duplicated from the xorg.log. Hong, what's your option?
Comment 7 Gordon Jin 2007-11-20 23:14:40 UTC
But 11598 happens in startx, while we need REstart x here.

Seems like a dup, we have problem in CRT hotplug detect (he just hit it at the 1st start). I will attach the fix patch in his bug to see if the problem will be fixed.
