[Bug 1812373] Re: Lock screen stopped working

2019-01-18 Thread Reuben Thomas via ubuntu-bugs
In case it was a kernel problem (I have also had a kernel update since I
last rebooted, from 4.15.0-42 to -43), I installed the latest HWE 18.04
kernel, but that did not help.

I should note that in fact the screen shield *does* sometimes activate;
but when it does, pressing a key reveals only the grey background, not
the login dialog.

Another potential culprit might be gdm3, but of course there has been no
update to that package recently.

I tried building 3.28.3-0ubuntu0.18.04.3 and installing that, but that
doesn't fix the problem, so it looks as though the cause may lie
elsewhere, in some other update that has happened in the same period.

(The issue doesn't seem to me to be serious enough to warrant keeping
the bug private.)
