gui-vm's /tmp/tmp-display* is not cleaned during logout

[jkuro-tii]

Scenario:
- log into the laptop
- check the /tmp/tmp-display* files on the gui-vm

Expected Behavior:
Only current files related to the active session should be present in the /tmp directory. Old or unnecessary files should be cleaned up automatically.

Actual Behavior:
Each login creates a new set of files in the /tmp/tmp-display* directory, and these files persist across sessions. This leads to an accumulation of unnecessary files.

Example log:
[ghaf@gui-vm:~]$ ls  /tmp/tmp-display*
/tmp/tmp-display-config.dtUgkGR  /tmp/tmp-display-config.QzBPJkc  /tmp/tmp-display-config.vRiulTY
/tmp/tmp-display-config.ns9ZK2c  /tmp/tmp-display-config.s6WCcmk  /tmp/tmp-display-config.YQYcPw9

[ghaf@gui-vm:~]$ # next login

[ghaf@gui-vm:~]$ ls  /tmp/tmp-display*
/tmp/tmp-display-config.8ZIeYBY  /tmp/tmp-display-config.ns9ZK2c  /tmp/tmp-display-config.QzBPJkc  /tmp/tmp-display-config.vRiulTY  /tmp/tmp-display-config.z5mAzaX
