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).

Let me know if I can provide more information. Thanks so much for all the good work, I really enjoy my Debian system!
