First things first. The new kernel will automatically detect the modes supported by your TV. So before changing modes run "xrandr -q" to get a list of supported modes. It should list something like 1920x1080 @ 25 Hz or 30 Hz. Then use xrandr to switch modes. e.g. xrandr --output HDMI2 --mode 1920x1080 --rate 30 > I also attached output dmesg with drm.debug=0xe The file didnt come through. -- Peter (A907 E02F A6E5 0CD2 34CD 20D2 6760 79C5 AC40 DD6B) -------------- next part -------------- A non-text attachment was scrubbed...
