Title: Touchpad freeze after suspend (lost sync) Status in linux package in Ubuntu: Confirmed Bug description: On a Lenovo 300e (Winbook w. touch), after suspend (after reopening the screen) a problem occurs with the touchpad. With original and latest bios, on Ubuntu 18.04 and 18.10. Pointer control via the pen on the touchscreen works right away but the touchpad initially fails to activate after suspend. The problem is logged in the syslog: Nov 13 18:10:30 laptop kernel: [47069.932348] psmouse serio1: Touchpad at isa0060/serio1/input0 lost sync at byte 6 Nov 13 18:10:30 laptop kernel: [47069.941838] psmouse serio1: Touchpad at isa0060/serio1/input0 lost sync at byte 6 Nov 13 18:10:30 laptop kernel: [47069.951256] psmouse serio1: Touchpad at isa0060/serio1/input0 lost sync at byte 6 Nov 13 18:10:30 laptop kernel: [47069.960764] psmouse serio1: Touchpad at isa0060/serio1/input0 lost sync at byte 6 Nov 13 18:10:30 laptop kernel: [47069.970321] psmouse serio1: Touchpad at isa0060/serio1/input0 lost sync at byte 6 Nov 13 18:10:30 laptop kernel: [47069.970330] psmouse serio1: issuing reconnect request The above sequence occurs a large number of times.
