Comment 17 for bug 1801609

Few more things:

- Does running "dm-tool switch-to-greeter" instead trigger the bug?
- Does simply waiting at the login screen for 10 minutes trigger the bug?
- Can the bug be reproduced after installing and booting an older kernel version? I suggest to test with 4.15 (version used in 18.04).
