Hello all,
I've got an HP laptop with a usb touchscreen. I'm not sure it's a bug in X or the kernel but the
pointer will jump to a spot in the upper right corner at random intervals. Sometimes it can go hours
between jumps and sometimes it jumps every second or two making the laptop virtually unusable. The
kernel is 3.14.0-rc5, though this has been happening with every kernel since I got the laptop 4 months
ago.
I've included all the information that I could think of that might be relevant.
Thanks,
/Chris
