Comment # 44 on bug 1132926 from Otrebor Igorig

So now this bug has become a bit dated. I'd like to suggest to close this one.
I am using kernel version 5.3.18-150300.59.60-default directly from the os
package repository. After a number of update cycles the external monitor does
what I want. It still has some timing issues when initializing, but I somehow
got used to them.

re: timing issues
The monitor needs to be in an active state for the driver to act correctly. I
do this by manually waking up the monitor first. Then I set the driver to
adjust the monitor as I want it. This works reliably. Having the monitor in
passive state does still not work and needs multiple cycles of configuration
play-around. btw. My MacBookPro does not have these timing issues using the
very same monitor.
