Title:
GDM/gnome-shell crash/freeze when switching keyboard layouts
Status in gnome-shell package in Ubuntu:
Expired
Bug description:
on my pc there are multiple keyboard layouts configured.(EN/JA/DE)
When using the keyboard shortcut to switch the layout (Super+Space) in some
situations (criteria not entirely clear) the whole UI freezes up and becomes
unresponsive. The only workaround is a hard poweroff and reboot of the system
which is rather convenient if this happens multiple times during a work day.
When switching to another terminal (Alt+F2 etc) I cam see
`/usr/lib/gdm3/gdm-x-session` having a high CPU load.
In the attached syslog file, there are repeated entries about
1) all input devices being removed
2) systemd-logind being paused
