Not sure if this is a problem with my hardware, but my Linux (Gateway) laptop can only look around while moving in one specific circumstance: when I keep holding the touchpad and sprint. I use arch btw
Solution: Lower Palm Check™ sensitivity or disable “Disable touchpad while typing”, which serves to prevent accidental touching of the touchpad while typing, hence “Palm”
Haha, yes, but I find pairing my mouse between two computers a little bit annoying.
Try a KVM switch, pretty cheap and very worth it
