[REGRESSION] kernel 3.5 / drm mode probe problem on i915GM
From: Knut Petersen
Date: Thu Aug 02 2012 - 05:19:02 EST
Hi!
On an AOpen i915GMm-hfs a monitor connected to DVI-1 works well with both kernel 3.4.7 and 3.5.
A monitor connected to VGA-1 boots to 1280x1024 with kernel 3.4.7 and 1024x768 with kernel 3.5.
kernel 3.5
