Thx. There was some discussion in the bko ticket and now it seems like it's not a regression (sorry for the noise) -- and the root of the problem apparently is a known firmware issue of the particular laptop: https://bugzilla.kernel.org/show_bug.cgi?id=214775 Thx again! Ciao, Thorsten #regzbot invalid: not a regression, see https://bugzilla.kernel.org/show_bug.cgi?id=215747 for details >>> Nico Schottelius 2022-03-26 19:27:06 UTC >>> >>> Created attachment 300619 [details] >>> dmesg >>> >>> TL;DR: >>> >>> Suspending and resume makes the ELAN0670:00 trackpad sluggish (very hard to move the pointer) and the energy usage of the notebook is about 3 times higher than before suspend. >>> >>> Background: >>> >>> >>> On a Lenovo X1 Nano the trackpad works fine until suspend/resume.The estimated battery runtime PRIOR to suspend/resume is 8h 43m.
