Touchpad not detected on HP 255 G2.

**m1ksu** · June 4th, 2017

Title pretty much explains it all. The touchpad is not being detected, thus, it doesn't work. But, some times, it does work. Or it did. I don't know what caused it to function in the past, but it dies after a restart. If I get any help on this, thank you.

Code:

 lshal -u "$(hal-find-by-capability --capability input.touchpad)"

also returns nothing.

It would be interesting to see if a newer kernel works better. You could try a live boot of 17.04 for comparison.

I wonder if making an entry in /etc/X11/xorg.conf (or, a file in /etc/X11/xorg.conf.d) will get it recognized?
