Sometimes touchpad doesn't work

Hi,
It is a samsung book2 750XED, sometimes when I start the system the touchpad does not work, I have to reboot the system and it starts working.
Any suggestion?

Re: Sometimes touchpad doesn't work

Don't grep - if there're i2c issues, your very narrow filter would miss them.

Ceterum censeo: is there a parallel windows installation?
Oh, and does Fn+F5  toggle the touchpad?

No windows installation, just arch.
Fn+F5 does not activate or deactivate the touchpad.

Could it be something related to this? "hid-multitouch: probe of 0018:0911:5288.0001 failed with error -22"

Re: Sometimes touchpad doesn't work

It's the relevant device, so yes.
Likely some race condition, so compare the order of events?
