Public bug reported:
This bug happens every single day, even after rebooting and updating.
I have 3 4k monitors with 150% zoom (extended mode).
On the late evening, I lock the workstation and the monitors goes to sleep (the
PC is still wake up and stays accessible all the time from the network).
Every morning I log into Ubuntu 24 and the 2nd and 3rd monitor are mirrored
instead of extended.
From the configuration there is nothing you can do to set the correct
configuration.
I have to disconnect the 3rd monitor and reattach. But as soon as I
reattach the monitor, the Ubuntu shell crashes (the white screen with
the logout button).
I repeat: this happens every single day.
This morning i tried to use ubuntu-bug to report the logs, but the
ubuntu-bug hangs the machine completely as I reported in another manual
bug two minutes ago. For this reason the attached log is the same as it
contains both events.
I have two NVida RTX4060Ti plugged in:
- one is virtualized in a VM using IOMMU (not used at all by the host)
- the other is used by the host for all the three monitors
If I use the embedded Intel graphics for the third monitor, the monitor
configuration is completely drunk (monitors shows a zoomed shell and
there is no way xrandr or the shell settings can fix it).
What hardware can be used on Ubuntu to have a stable working
workstation? I reinstalled Ubuntu 3 times to avoid issues with the
Upgrade from 22 to 24 and still the machine hangs/freezes even on a
totally different hardware (with AMD hardware the situation is even
worse).
