Hello folks,
I'm experiencing issues with the touchpad after resuming from suspend.
System:
- Lenovo ThinkPad X1 Carbon Gen9
- FreeBSD 13.1-STABLE (March 27 2022)
After a regular boot, the touchpad is working as expected. If I then use zzz(8)
to suspend the system and resume afterwards, the touchpad is behaving weirdly:
- Regular cursor movements (one finger) are very, very laggy. It feels like
the system is updating the cursor's position only once ever 800ms (or there
about).
- Anything multi-touch related such as two-finger scrolling is not working at
all.
The keyboard and the trackpoint (joystick-thingy) continue to work as expected
after resuming from suspend.
I'm using libinput as the input driver. Here's the relevant part of my Xorg
config:
Section "InputClass"
Identifier "libinput touchpad catchall"
Driver "libinput"
MatchIsTouchpad "on"
MatchDevicePath "/dev/input/event*"
Option "AccelSpeed" "0.5"
Option "ClickMethod" "clickfinger"
Option "DisableWhileTyping" "on"
Option "HorizontalScrolling" "on"
Option "LeftHanded" "off"
Option "NaturalScrolling" "on"
Option "ScrollMethod" "twofinger"
Option "Tapping" "on"
Option "TappingDrag" "on"
Option "TappingDragLock" "off"
EndSection
Any idea how to track down the problem, what the problem could be or how to fix
this?
I could not spot anything obviously in Xorg's log.
Best regards,
~ Joel
