https://bugzilla.novell.com/show_bug.cgi?id=754697 https://bugzilla.novell.com/show_bug.cgi?id=754697#c1 --- Comment #1 from Michael Lashkevich 2012-03-30 18:26:28 UTC --- I found that the screen returns to life as soon as I attach an external monitor to my laptop. As a workaround I added the "enable_mtrr_cleanup" and "nopat" kernel options (I found this recipe somewhere on the net). It works for boot, but not for resume from hibernation. By the way, the screen remains blank forever, if I do not use the "intel" xorg driver (which seems buggy). -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I tried to boot with kernel param "i915.modeset=0" , it doesn't occure the issue again but can't detect second monitor. so I have to go for ""i915.modeset=1",in this mode , sometimes black sceen too, but can detect second monitor. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
