My touchpad suddenly stopped working well on my Dell Latitude laptop with Ubuntu 22.04 - when I press the touchpad it works, but sliding to move the cursor doesn't work nor does tapping the touchpad to click anything. The touchpad is activated in my settings, but only pressing works, which means it is being detected to some extent - however I don't see it when I run lspci:

I've also tried xinput disable and xinput enable and it didn't change anything. I'd appreciate any help on this.
