<span class="quote">> Chris, I tried both methods. The first one, failed with the same error

Forgot to give DP2 a mode...
echo 0xe > /sys/modules/drm/parameters/debug
xrandr --output LVDS1 --off --output DP1 --off --output DP2 --off
xrandr --output DP1 --preferred --primary -pos 0x0 -output DP2 --preferred
--pos 3520x0
xrandr --output LVDS1 --preferred --pos 1600x0
echo 0 > /sys/modules/drm/parameters/debug
If that doesn't work, please attach the dmesg.</pre>
