Your ASUS and i8042 chipset have a lot of dissussion at : I had a similar event happen installing a different linux on a Toshiba Satellite so I used a mouse for a while and before I could figure out what went wrong, the touchpad was working again You could install pastebinit and upload a couple files that might helpĪnd just copy/paste the URL's from the last two commands in your next post. Im using an external gaming mouse right now as a derivative. Take a look at my Xinput List (Kubuntu 14.04) It just seems like even though the Synaptics is installed it won't enable or something. Should I follow through or is it different? I'm running updated Arch Linux with standard kernel on an ASUS Zenbook 14 Laptop.Well, I've installed Kubuntu now, and the problem still persists. The mouse polling rate (tested with evhz) averages 140hz and does not go down when it starts lagging. Looking at the output of "libinput debug-events -device /dev/input/(my touchpad device)" I can visually see the delay between my finger movement and when the touchpad move events print (only when the mouse is lagging). I don't see anything suspicious in dmesg. When I plug in an external mouse it has no lag, and the touchpad can be lagging at the exact same time the external mouse is not. This bug happens under both the libinput and Synaptics touchpad drivers. I have not been able to figure out if anything specific is correlated to it happening, it just seems to start and then go away at random times. I'm starting to get suspicious that this may be a bug in the kernel itself. Let me know if I should post any additional info. The mouse still moves smoothly on the screen, but there's a 300-500ms or so delay between when my finger moves and when the mouse does. I want to be clear that it does NOT get "jumpy". Every once in a while (fairly often) my touchpad mouse gets very laggy.
