Hello all,

I'm recently experiencing a weird issue which is also a little
frustrating as it make me fear to close my laptop's lid to put it to
sleep.

I have cnofigured my laptop to go to sleep when I close the lid. The
issue is that when I re-open it after a close the trackpad stops
working! I have to reboot to make it work again. I can't find what's
the issue but I could help with finding the issue if someone helps me.
