Firmware update to my CableMatters thunderbolt/USB-C/PD dock seems to have fixed my issues (no occurances since).
I suppose I have to assume that improved driver support in the newer kernel may have exposed some issues in the hardware that were fixed with the update. Notably I can run dual 1440p with full 4k panel on the laptop open as well, so one of those 3 display quirks I mentioned also disappeared. -- 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/1841826 Title: Going to sleep instead of logging in while lid closed & external display To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-settings-daemon/+bug/1841826/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
