I have an acer aspire R14 2-in-one convertible laptop. The error I'm encountering is that most times I resume from suspend, the keyboard does not work. I have tried numerous fixes such as disabling rfkill or adding "atkdb.reset" to /etc/default/grub, trying to renable with xinput didnt work either. Because I'm on a 2 in one convertible, I suspect it may have something to do with the driver that disables the keyboard when in tablet mode. I did try running dmesg | grep keyboard and got this output:

I believe I have figured out a solution, as recommended by a friend. Adding i8042.noaux=1 to grub boot options completely eliminated the issue. Other topics had recommended atkdb.reset i8042.nomux which didn't work; in fact, i8042.nomux completely messed up my keyboard.
