Source: linux Version: 4.12.6-1 Severity: wishlist Dear Maintainer, During boot, the 4.12 kernel suggests some additional kernel options should be enabled to improve touchpad support: Sep 8 14:18:15 muta kernel: [ 4.089833] psmouse serio1: synaptics: queried max coordinates: x [..5712], y [..4780] Sep 8 14:18:15 muta kernel: [ 4.121930] psmouse serio1: synaptics: queried min coordinates: x [1232..], y [1074..] Sep 8 14:18:15 muta kernel: [ 4.121939] psmouse serio1: synaptics: The touchpad can support a better bus than the too old PS/2 protocol.
