[Bryce Harrington <703210@xxxxxxxxxxxxxxxxxx>]

I notice this in your XorgLog:

[  5994.912] (EE) intel(0): Failed to submit batch buffer, expect
rendering corruption or even a frozen display: Invalid argument.

Subsequent to that it re-acquires the touchpad (and monitor, and usb
mouse):

[  5995.208] (--) SynPS/2 Synaptics TouchPad: touchpad found

Working theory...  the power adapter causes a gpu lockup that the kernel
recovers from, but X doesn't reload the touchpad settings and thus
misses a quirk/workaround for the jumpy cursor.

Can you test this theory, by booting fresh on battery, then running
'tail -f /var/log/Xorg.0.log' in a window, and plug in your power
adapter.  If the theory is true, the batch buffer error message should
print out, and then the touchpad should start behaving weird.


** Description changed:

  Binary package hint: xserver-xorg-input-synaptics
  
  I'm in Israel right now and I have my adapter set up properly with my
  laptop, but the touchpad is flipping out.
  
  Cursor jumps randomly and clicks even when I haven't clicked.
  
  My USB mouse is not affected and the problem with the touchpad
  disappears once unplugged.
