Hi. I too have the same model and encountered the same issues with the touchpad after resume. I’ve updated the BIOS to the latest DMCN32WW (release date 14/07/2020) but this didn’t resolve the touchpad issues.
Running the EnableTouchPad.sh on terminal after resuming from suspend activates the touchpad. However, it doesn’t work as systemd:
EnableTouchpad.sh[30605]: Unable to connect to X server
The command seems to run before X server graphical interface is running. I’ve tried other alternatives as well.
- Edited the enabletouchpad.service to try to apply after the graphical interface is running. Doesn’t work. Same error message “Unable to connect to X server”. My file now includes:
[Unit]
Description=Enables touchpad again after resuming

https://archived.forum.manjaro.org/t/solved-clevo-nh55-laptop-touchpad-hang-freezes-after-lid-close/104089/54 - didn’t work but I expected it to fail;
-
SYNA3602 touchpad not working at all - #24 by cscs - modprobe works (doesn’t need X server to run) for a couple of seconds and then it’s disabled. I also noticed that when re-enabling the touchpad manually my inverted scroll setting reverted to default;
-
compiled most recent kernel (5.8.2) but continued to have issues with the touchpad;
-
included the
xinput --enable 'PNP0C50:00 06CB:CDB0 Touchpad'command in the ~/.xinitrc file but it also didn’t work.
I’ve managed the touchpad issue by assigning the F9 key to toggle the touchpad. Also, when the screen opens it doesn’t wake the OS. I need to press a key to wake up the device.
Other issues I’ve had with the slim 7:
-
suspend to ram is not advertised by the BIOS to the OS. ACPI S3 sleep is unavailable by default. I followed this post to enable sleep to RAM - https://www.reddit.com/r/linuxhardware/comments/i28nm5/ideapad_14are05_s3_sleep_fix/
-
brightness jumps to max when booting. Resolved this by setting a manual brightness in the ‘Power Management’ settings.
Overall, the laptop is running fine for the most part. Completely idle it drains around 2.5W - 3W on battery with very dim screen. I’m using tlp and auto-cpufreq which allows the cpu to ramp up under heavy load with turbo enabled a few seconds.
