Now I have a related problem at work, where the external monitors were
not detected after plugging in the laptop in the docking station and
opening the lid. Turning off and on one monitor resulted in detection
(in poor resolution) but not the second external one. When both are
turned off and on, the system hangs until I disconnect the USB-C cable
to the docking station.
A terminal window was open where lsusb was my previous command. During
the unresponsive period whilst the docking station was connected, I
could press <arrow up>,<enter> without seeing anything on the screen,
but after disconnecting the docking station again the command and output
where shown:
$ lsusb -tv

Title:
Maximum resolution not available after suspend / screen detach
Status in xorg package in Ubuntu:
New
Bug description:
I have a fresh install of Ubuntu 22.04.3, using the default Wayland, on my
laptop which is used at two locations:
- at work I have my primary built-in 4K display and 2 additional 1920x1080
monitor connected to a HP DisplayLink docking station using DP, connected to my
laptop using USB-C
- at home, I have my primary built-in 4K display and an additional 4x monitor
directly connected using the mini-DP
After boot, everything works perfect. However, after working at work,
putting the laptop into suspend (by closing the lid), attaching to my
monitor at home and opening the lid again, I get my external display
at a poor resolution which I cannot change to 4K in the settings menu:
the 4K resolution is not available. Also in xrandr, the 4K resolution
is not available. The resolution is however correctly provided by the
monitor at all times:
$ sudo get-edid -b 8 | parse-edid
8
This is read-edid version 3.0.2. Prepare for some fun.
Attempting to use i2c interface
Only trying 8 as per your request.
256-byte EDID successfully retrieved from i2c bus 8
Looks like i2c was successful. Have a good day.

Previously, using Ubuntu 20.04, I've had the same issue using Xorg, which
could easily be solved by unplugging the external monitor and plugging in back
again, which worked most of the times, sometimes only after a few retries. Now,
with Ubuntu 22.04.3 and Wayland, this doesn't work anymore. Logging out in this
situation and logging in again in an Xorg session doesn't help either. Only a
reboot seems to help.
Additional debug information at a situation with wrong resolution can
be provided on Monday, as I just rebooted again :-)
