<pre>I can confirm that my problems are fixed as of 5.3.7, and I'm fairly certain
it's due to
<a href="https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=26b1d3b527e7bf3e24b814d617866ac5199ce68d">https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=26b1d3b527e7bf3e24b814d617866ac5199ce68d</a>,
because when I rename the Xorg binary to tmp-Xorg, I can reproduce it again.
I can reproduce it reliably using this sequence of events:
1. connect laptop to ThinkPad Ultra Dock
2. activate both external displays using xrandr
3. deactivate external displays again
4. suspend laptop
5. resume laptop
6. xset dpms force off</pre>
