Problem occurs both on Ubuntu 18.04 and Arch Linux.

After about 5 minutes of booting into my OS, click events from the touchpad and external mouse stop working. Scroll events will behave oddly - sometimes switching to horizontal scrolling and sometimes not working at all.

I've tested with both xev and evtest and tried disabling and enabling the trackpad with xinput. Click events are registered in evtest but are not found in xev.

The fact that this occurs both in Ubuntu 18.04 and Arch makes me think this is a hardware issue, but I have hit a dead end in trying to debug this. Does anyone have any advice or suggestions?

Laptop is a Lenovo Thinkpad p50s. If any other hardware specs are required just let me know.

Don't really want to talk about this, but I noticed I had a second usb mouse plugged in that I had completely forgot about that was causing the issue.
