I am on a Lenovo N24 laptop. When this device resumes after closing the lid, the mouse freezes and is unusable. After right-clicking multiple times the touchpad resumes working. I am seeing the following in the logs: [ 1188.690138] psmouse serio1: Touchpad at isa0060/serio1/input0 lost sync at byte 6 [ 1188.699636] psmouse serio1: Touchpad at isa0060/serio1/input0 lost sync at byte 6 [ 1188.709124] psmouse serio1: Touchpad at isa0060/serio1/input0 lost sync at byte 6 [ 1188.718557] psmouse serio1: Touchpad at isa0060/serio1/input0 lost sync at byte 6 [ 1188.728110] psmouse serio1: Touchpad at isa0060/serio1/input0 lost sync at byte 6 [ 1188.975964] psmouse serio1: Touchpad at isa0060/serio1/input0 lost sync at byte 6 [ 1188.985456] psmouse serio1: Touchpad at isa0060/serio1/input0 lost sync at byte 6 [ 1188.994954] psmouse serio1: Touchpad at isa0060/serio1/input0 lost sync at byte 6 [ 1189.004443] psmouse serio1: Touchpad at isa0060/serio1/input0 lost sync at byte 6 [ 1189.013930] psmouse serio1: Touchpad at isa0060/serio1/input0 lost sync at byte 6 This device has an ETPS/2 Elantech Touchpad. I am on kernel version: 5.15.117-19629-gf1eb3139d206 Currently the device suspends to ram when the lid closes. When the device idles without the lid closing, the touchpad works fine on resume. I have tried adding various i8042 and psmouse kernel parameters from searching different forums related to these error messages, but none of them fix the issue. I have tried - psmouse.resetafter=0 - psmouse.resetafter=1 - i8042.nomux=1 - i8042.resetafter=1/0 - i8042.reset=1 i8042.nomux=1 - i8042.noloop=1 i8042.nopnp=1 i8042.nomux=1 i8042.reset=1 I was able to resolve this issue by doing `modprobe -r psmouse && modprobe.psmouse proto=imps`. proto=bare and proto=exps also resolve the issue. However, with those options enabled I can no longer use gestures like two-finger scroll. This issue reproduces on ChromeOS Flex and Ubuntu 22.04 but not on Windows. On Windows the touchpad resuming after closing the lid works fine. What can I do to resolve this issue while also keeping touchpad gestures? Any help is greatly appreciated!
