Public bug reported:

Package: glhack 1.2-2
Ubuntu: Ubuntu 14.04.1 LTS 64-bit

Steps to reproduce: run glhack from a terminal.

Upon running GLhack, my resolution is changed to 800x600. GLhack then
crashes, leaving the resolution at that level (with panning enabled). I
have to use xrandr to fix it, or log out and back in.

I'm using the proprietary nvidia driver v 331.38 on a GeForce G105M.

Here's a terminal session showing the problem:

$ xrandr
Screen 0: minimum 8 x 8, current 1366 x 768, maximum 8192 x 8192
VGA-0 disconnected (normal left inverted right x axis y axis)
