Created attachment 193395 [details] dmesg.boot It looks like the touchpad on the Dell Latitude 5580 isn't supported. Funny enough, the touchpad on the 5570 is. I guess Dell must have switched touchpads in the 5580 from the 5570.

I have two of these laptops which will be used for interns. I can have them use a USB mouse for now, but it'd be nice to have support for the touchpad.

can you grab pci / usb from 5570 also and compare?

Having a Dell 5580, I took a deeper look at this. It seems the problem is more that the touchpad on the 5580 is now using i2c. One can get it to work on 12.1-RELEASE if one isn't scared of getting one's hands dirty. You need to: Modify the ig4 driver so that it gets interrupts: See comment by wulf from July 27, 2019 on review D16698. Use wulf7's iichid driver on github. Rebuild Xserver with evdev support (bug #222609). You may still need to tweak the configuration for the keyboard (see bug #196678, comment 121). I guess all of this stuff is slowly making progress to the next release and ports.
