Lenovo Thinkpad T460s: TPPS/2 IBM TrackPoint not detected
Sometimes, the trackpoint is not present in libinput list-devices
, even though the kernel seems to work fine, as e.g. dmesg has a line:
[ 24.684710] input: TPPS/2 IBM TrackPoint as /devices/platform/i8042/serio1/serio2/input/input19
Both the red 'nipple' and three buttons do not work in Wayland, but their pressure is detected by doas cat /dev/input/mouse1
. Usually, rebooting solves the issue, and it appears again as
