I used the solutions in this question to align my two monitors. My left monitor is High DPI 3840x2160 while the right is scaled 2x from 2560x1440 and rotated to portrait mode; they share a bottom edge.
xrandr --output eDP1 --scale 1x1 --mode 3840x2160 --pos 0x2800 --primary --output DP1 --scale 2x2 --mode 2560x1440 --pos 3840x0 --rotate left
This works but has the following undesirable characteristics:
- There's some artifacts when dragging windows -- they leave a black trail over the background.
- The mouse pointer disappears when it gets within around 100px of the right edge of the right monitor. It still functions as a pointer but I cannot see it.
Any ideas for how I can correct these issues?
