Hi everyone !

I'm facing a stubborn issue that is a real pain. I'm using a Lenovo Thinkpad E531 laptop that has been working great for 5 years, but I've been having issues with the touchpad for a couple of weeks. I have tried to change the distribution, including :
- MX Linux
- Antergos
- Manjaro
- Ubuntu

Whatever the distribution, when I close the lid, the touchpad stops working. I can't click, scroll, or even move the mouse. If I plug in an external mouse, everything works perfectly. Depending on the various distributions settings, closing the lid might either suspend the system or simply deactivate the screen, but same result : no touchpad when I open it again.

Does someone have an idea about how to fix that ?

Thanks !
