Hey all, new to this forum so apologies for any failures in following customs.
I am working with a Dell XPS XPS 15 9575 (080D) and fedora 30. Since Fedora 28ish, I’ve had an issue where the cursor will jump around or not move at all while using the touchpad. The cursor does not jump or do anything erratic when I am not touching the touchpad. The start and stop of this behavior does not seem to coincide with anything in particular. When the chaotic behavior occurs, the cursor still responds to taps as if clicked, however, the cursor will often not move or act as if I am pressing the right mouse button/two finger tap to right click. The touchscreen seems to operate just fine.
I am not sure how I would go about troubleshooting this. In /proc/interrupts, I see the interrupt lines that are responsible for it (for me it is DELL080D:00 and idma64.1, i2c_designware.1 or at least these increment when I use the touchpad under normal circumstances), but these do not increment without me touching the touchpad.
Any assistance on troubleshooting this would be great! Thank you!
