https://bugzilla.kernel.org/show_bug.cgi?id=66871 --- Comment #9 from Erik Edwards <erik@xxxxxxxxxxxxxx> --- (In reply to Alex Deucher from comment #8) > Can you use git to bisect what commit caused the regression? Google for git > bisect howto. 3.12.5 Found a workaround: Allow nromal boot to graphical environment with all monitors powered on. After GUI login is displayed and DVI connected monitor is blank do <ctrl><alt>F2 to switch to text console. Wait until all working displayas are stable then power off and power on non-fucntional display via its power button. Wait until all displays are stable then return to GUI. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
