Greetings, sometimes my touchpad doesn't seem to react instantly to clicks or move- ments. And after booting I find lines like the following in my kernel log:
Jun 24 17:50:38 tux kernel: [ 2.545000] psmouse serio2: synaptics: queried max coordinates: x [..5674], y [..4758] Jun 24 17:50:38 tux kernel: [ 2.661921] psmouse serio2: synaptics: queried min coordinates: x [1268..], y [1096..] Jun 24 17:50:38 tux kernel: [ 2.662824] psmouse serio2: synaptics: Your touchpad (PNP: SYN1218 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.
