Subject: [PATCH libinput] touchpad: require at least 3 events before enabling
|
|
||||||
trackpoint palm detection
|
|
||||||
|
|
||||||
Some trackpoints, notably the one on the Lenovo T460s have a tendency to send
|
|
||||||
the odd event even when they're not actually used. Trackpoint events trigger
|
|
||||||
palm detection (see 0210f1fee193) and thus effectively disable the touchpad,
|
|
||||||
causing the touchpad to appear nonresponsive.
|
|
||||||
|
|
||||||
Fix this by requiring at least 3 events from a trackpoint before palm
|
|
||||||
detection is enabled. For normal use it's hard enough to trigger a single
|
|
||||||
event anyway so this should not affect the normal use-case.
|
|
