Hello users@,
I've upgraded my thinkpad from fc31 to 33 a few weeks ago, and since
then I'm having problems with my external monitor.
First, how things used to work: I keep my laptop in its dock, on which I
have plugged in an VGA monitor through a KVM. When I undocked (or
unplugged the display), i3 kept the output on and all workspaces on the
display they were, so when I docked back in, the setup is unmodified.
Same thing happened when suspending: on resuming, the external display
is still recognized and workspaces stayed put.
But since upgrading to Fedora 33, whenever I suspend the computer (or
unplug it from the dock), the external display gets removed from the
available outputs and all workspaces move over.
Looking at bodhi, the i3 version stayed the same, so I suspect this
might be an X (configuration?) change in between the Fedora versions.
(xorg-x11-server was upgraded from 1.20.6 to 1.20.9, so maybe that's the
culprit?)
Any help tracking this issue down is greatly appreciated.
Thanks,
tobi
I have looked in /var/log/Xorg.0.log, and it has detected the absence of
the display (but I don't have an old fc31 log to compare against):
<unplugging>
[155121.055] (II) intel(0): Enabled output DP2-3
[155121.055] (II) intel(0): Disabled output DP2-1
[155121.055] (II) intel(0): Disabled output DP2-2
<plugging back in>
[155129.654] (II) intel(0): Enabled output DP2-1
[155129.657] (II) intel(0): Enabled output DP2-2
[155129.660] (II) intel(0): Enabled output DP2-3
[155129.821] (II) intel(0): Enabled output DP2-3
[155129.823] (II) intel(0): Enabled output DP2-3
i3-dump-log shows that i3 then moves the workspaces over; it didn't do
that in the past AFAICT.
