Before reboot I had:
* Laptop internal monitor on
* Samsung 34" external monitor on, with USB-C
* Aces 24" external monitor on, with HDML
Rebooted without changing anything.
* The Samsung 34" / USB-C connected external monitor did _not_ come to life.
* The Acer 24" / HDMI second external
I've got it working one more time.
* Disconnected the HDMI.
* Rebooted - with USB-C to the monitor connected.
* The external monitor did not register.
In addition to the monitor a Lenovo network adapter (8P8C for
CAT5/CAT6/..) is connected.
I tailed /var/log/syslog and /var/log/kern.log
I kept
Public bug reported:
The external Samsung 34" monitor connects fine with HDMI, but not on USB-C.
It worked for a short amount of time at one point early after installing Ubuntu
22.04, but not since.
No difference with disconnect / reconnect, reboot, etc.
