Hello, 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. Greg KH suggested that I try later kernel versions, and I've tried 6.4 and 6.1 and the issue is present on both of those versions. This issue is also present on 5.10. 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!
