"login as other user" is a no-op

[elatllat]

login as user b, lock the screen then press "login as other user" and you will not be offered the option to login as user a, control+alt+f1 seems to be the hidden workaround.

Regarding the "No upgrade log present" I think the script is broken;

> du /var/log/apt/history.log*
8 /var/log/apt/history.log
8 /var/log/apt/history.log.1.gz
36 /var/log/apt/history.log.2.gz
