Then I tried to suspend; resume with monitor attached. Didn't work either - see second log file.
(One thing I'm wondering: I *am* using the same brand and type of monitor, connected to the same brand and type of dock, at *different places*. Could that be the culprit? I.e. having used the LG Electronics HDR 4K somewhere, then attaching the laptop to the same brand and type of monitor at a different place, with a different dock, would that possibly lead to this behaviour? Could others comment on this, i.e. do you experience this behaviour when using a single dock / single work place?) ** Attachment added: "journal2.log" https://bugs.launchpad.net/gnome-shell/+bug/1970495/+attachment/5691434/+files/journal2.log -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1970495 Title: Window manager freezes when plugging in USB-C dock with external monitor ([drm] *ERROR* mstb 00000000f21f0a30 port 1: DPCD read on addr 0x4b0 for 1 bytes NAKed) To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-shell/+bug/1970495/+subscriptions -- desktop-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
