Plug external 2560x1440 DisplayPort monitor into laptop. 2. echo 'exec startkde' > ~/.xinitrc 3. startx 4. xrandr --output DP1 --auto This used to result in DP1 switching to 2560x1440, but KWin getting stuck waiting on a buffer idle event that never came, so you'd only see a 1920x1080 screen in the top left corner of the display, with either black or white bars in the other area. Other than the mouse cursor, nothing worked. With these patches, X works as expected. Thanks for the fixes, Keith!
