Bug ID: 450925
Summary: Jittery cursor after suspend/hibernate
Product: Powerdevil
Version: unspecified
Platform: unspecified
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: lyrix...@gmx.com
Target Milestone: ---
I have encountered this bug, apparently it has been here for a while. Not kde
speciffic, not sure what it is but I can confirm that when the system goes to
suspend and after i turn it back on the cursor movement is extremelly jittery
and laggy. I ran a dmesg and a usb bus would say that it disconnected. Then i
would look in the touchpad settings and the touchpad device would not be there.
Maybe is the way it suspends?
I found out that once that happens you have to invoke a " sudo systemctl
suspend " then turn it back on and the problem would be solved immediately.
Maybe whatever mechanism its being used to suspend can append a workarround for
this?
The laptop that has this issue is my Thinkpad T480, with my T470 I dont recall
having this issue.
STEPS TO REPRODUCE
1. wait for the system to suspend
2. turn it back on
3. touchpad /mouse cursor will have the issue (happens very often but i cant
say it will be 100% all the time)
OBSERVED RESULT
If i invoke a " sudo systemctl suspend " and bring the computer back on, the
issue is gone.
If i dont the issue remains.
