more info which might be important:
twice now in the past week when this bug has caused the x hang issue i have been unable to log in afterwards. i believe that both times (certainly the most recent) it was after i had ctrl+alt+f2 to a terminal and blindly logged in and run some command. in the most recent case the command was # dmesg > /root/dmsg
in this most recent case, the reason for being unable to log in afterwards was wrong permissions (owner) set on ~/.Xauthority
the permissions were 600 (which i think are correct) but owner and group was root.
once this was corrected i was able to log in again.
the first time of the two was similar in some ways. i had also blindly logged in to the terminal and run some command (killall firefox-esr, which i thought at the time might be causing the hang).
after rebooting (using ctrl+alt+del) the same permissions issue as previously described for .Xauthority was affecting a different file, also removing my ability to log in. this file was ~/.config/user-dirs.dirs
after changing the owner to my user i was able to log in again.
in both cases logging in as a different user than the one which was in use at the time of the crash, worked as normal.
a third item which might also be pertinent is the following:
for around the same amount of time that the x-hang issue has been affecting this machine (1-2 weeks?) when logging in with sddm or lightdm, if password is incorrect, the system re-asks for username/password right away. however if the password is CORRECT, the system hangs for two minutes before showing the desktop.
not sure if this one is related or not!
i'm using testing with lxqt
