synergy; Difficult to align 2 monitors horizontally aligned so that cursor can go out upward from both monitors

[130s]

While I was tryign to enable eGPU #1128, Ubuntu's monitor configs got changed -- builtin monitor's height got shorter from 1200 to 1080 so that only the 34 inch monitor is touching the upper bound of synergy, which resulted in moving up the cursor to another monitor via synergy is only possible from 34 inch.

Now, on Ubuntu's monitor config GUI, it's very difficult to visually reconfigure so that both monitors' top edge touch the upper bound. It's become like a masterpiece manual work, which requires time and luck.

Is there a way to configure this systematically in the way manual masterpiece work wouldn't be required?

Using arandr https://askubuntu.com/a/47656/24203 I created a .sh executable that seems do to configuration.

$ more ~/.config/xrandr/p16s_2-monitor.sh 
#!/bin/sh
xrandr --output DP-0 --off --output DP-1 --off --output DP-2 --off --output DP-3 --off --output HDMI-0 --off --output DP-4 --off --output DP-5 --off --output eDP-1-1 --primary --mode 1920x1200 --pos 0x0 --rotate normal --output HDMI-1-1 --mode 3440x1440 --pos 1920x0 --rotate normal --output DP-1-1 --off --output DP-1-2 --off --output DP-1-3 --off --output DP-1-4 --off

Let's add that .sh to SUCO.

The setting is reverted upon force-restart #1135 (comment) and executing the .sh file above doesn't seem to reapply the setting......:(

I meant the cursor did NOT move from the larger monitor up to another host's screen via synergy.

But after 1) running the .sh, 2) rebooting synergy, the issue is gone.
