[Pkg-utopia-maintainers] Bug#1121944: upower: Failure to resume after suspend

[Marten van Kerkwijk]

Package: upower
Version: 1.91.0-1
Severity: serious

Dear Maintainer,

After upgrading my Lenovo X1 Yoga gen8 laptop late November, I was no
longer able to suspend/resume reliably: it would look like the laptop
would suspend, but most times, I got a black screen and unresponsive
laptop on response, sometimes with a blinking capslock (suggesting
memory corruption).

After trial and error, I found suspend/resume worked fine from sddm or
from the console, i.e., the problem was KDE specific.  Looking at
upgrades done shortly before, I found that the culprit was upower and/or
libupower-glib3, both of which were upgraded from 1.90.10-1 to 1.91.0-1.
(Both are dependencies of plasma, so it makes sense that it happened only
on KDE.)

Downgrading to 1.90.10-1 seems to have solved the problem.

While trying to investigate, I looked at the logs, and there were
a few entries that stood out (and did not happen on succesful cycles).

Also, in case it is helpful, sometimes things did work, perhaps a bit
more often when on power.

Let me know if I can provide more information.

Thanks so much for all the good work, I really enjoy my Debian system!

All the best,

Marten
