I am using my tablet as an external monitor with VNC.
$ lsb_release -rd Description: Ubuntu 14.04.1 LTS Release: 14.04
$ xrandr --output DVI-I-2 --fb 3200x1080 --panning 0x0+0+0
$ xrandr | grep DVI-I-2
DVI-I-2 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 530mm x 300mm panning 3200x1080+0+0
Panning still happens. I had it working March 2013, I don't know when it stopped working as expected.
