Public bug reported:
Using a desktop with two users, it often hangs switching from one to
another. The console comes unresponsive, even text-only (ctrl-alt-f2)
does not show. System itself still runs, I can login over SSH. Process
for Xorg shows one full cpu used.
The system came up from hybernate, the graphical display showed password
entry for other user, the switch towared the one user showed the
password entry for the one user. After entering the password the display
turns black, with ctrl-alt-f2 not responding either.
Via ssh I can produce the following: (3-core cpu):
