Have been experiencing intermittent issues with the trackpad not working on resume, sometimes after a number of sleep cycles and sometimes every time. This also results in a refusal to sleep when in this state.
This has been an issue with at least the past few kernels. I’m on the latest 5.7 now.
Having run sudo modprobe -r psmouse && sudo modprobe -a psmouse all seems good … the trackpad sprang to life & the machine sleeps and wakes normally (an essential feature for me).
Reason for posting is to see if anyone else has (had) this issue and if my above “fix” worked long-term (it’s easy enough to reissue if it doesn’t though).
I’m not sure either on the kernel parameter stuff, yet. However, the machine has now had about 20 sleep and resume cycles without issue. I’m currently running a system upgrade & will see what happens then.
I’m about to find out! Will let you know just after 21:00 GMT if the first suspend/resume has worked & will update this thread again at the end of the night when I get back.
I might need to reapply the fix though as have just completed the system upgrade & rebooted. Will let you know if that’s the case. My machine typically gets 4 suspend & resume cycles per night when I go out.
First sleep & wake is fine. I’ve now tried this on multiple occasionsns this morning and the trackpad kas re–awakened every time so far, with the machine also sleeping (practically instantly) as desired… If it gives another 3 or 4 today and still holds up tomorrow for another session, I’ll consider it a likely success.
I’m tempted to do a series of sleep & wake cycles in the morning but Custard has decided the mouse is her domain tonight so sorry if there was an extraneous post just now.
ETA: as long as I have control of the keyboard, Custard is one of my Feline companions!
FETA: Having been suitably trampled and having done a number of sleep/wake cycles, all appears to be well, so far. Everything connects; no worries about mouse, KB or other external peripherals. Trackpad seems to work fine.
Aha! Now let’s see if it persists across sleep and wake cycles. It seems to have done so on my machine; tried a number of times during the night and the machine slept & woke promptly with no issues following the update & reboot, without re-issuing the modprobe commands.
This had been a persistent (and for me at least, rather inconvenient) issue.
