Title:

Status in linux package in Ubuntu:
Fix Committed
Bug description:
Touchpad on X1 Carbon G6 is slow and sloppy
Because:
[ 2.101906] psmouse serio1: synaptics: Your touchpad (PNP: LEN0091
PNP0f13) says it can support a different bus. If i2c-hid and hid-rmi are not
used, you might want to try setting psmouse.synaptics_intertouch to 1 and
report this to linux-in...@vger.kernel.org.
Adding kernel parameter psmouse.synaptics_intertouch=1 indeed fixes
it.
