Btw, I'm using OpenSUSE, so Kernel 3.16.6. Also xrandr output is much shorter than the ones posted here, is that normal when you use modeset=0? xrandr -q --verbose xrandr: Failed to get size of gamma for output default Screen 0: minimum 1920 x 1080, current 1920 x 1080, maximum 1920 x 1080 default connected primary 1920x1080+0+0 (0x180) normal (normal) 0mm x 0mm Identifier: 0x17f Timestamp: 7692 Subpixel: unknown Clones: CRTC: 0 CRTCs: 0 Transform: 1.000000 0.000000 0.000000 0.000000 1.000000 0.000000 0.000000 0.000000 1.000000 filter: 1920x1080 (0x180) 159.667MHz *current h: width 1920 start 0 end 0 total 1920 skew 0 clock 83.16KHz v: height 1080 start 0 end 0 total 1080 clock 77.00Hz -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
