https://bugzilla.kernel.org/show_bug.cgi?id=94171 --- Comment #4 from Felix Miata <mrmazda@xxxxxxxxxxxxx> --- Installed in a B85/Haswell/G3220 machine, the Cedar works as expected in openSUSE Tumbleweed with kernel 4.2.1 and openSUSE 13.1 with kernel 3.12.44 using: xrandr --dpi 120 --output DVI-0 --mode 1920x1080 --above VGA-0 --output VGA-0 --primary --mode 1680x1050 # ati dual but using X600 or X1300, both displays go black. With Fedora 23, Plasma 5 and kernel 4.2.2, with X1300 the 1680x1050 screen on VGA-0 works as expected but the 1920x1080 screen on DVI-0 is black. With X600 and Cedar, all 1920x2130 works as expected. Using xrandr --dpi 120 --output HDMI1 --mode 1920x1080 --above VGA1 --output VGA1 --primary --mode 1680x1050 # intel dual with the onboard video instead of X600, X1300 or Cedar, all OS/kernel combinations tried run Xorg as expected. -- 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
