Comment 1 for bug 1078695

I have a 'fix' for the bug which may work, but doesn't fix the underlying cause. If the proprietary drivers can be installed, or simply a different video driver, this may read the gamma and allow for re-sizing the display. I found a Live DVD (Linux Mint 14 Cinnamon) which caused the same problem of not reading the gamma, but when I installed nvidia-current under the Live session, I was able to get a gamma reading and re-size the display to add 1280x1024@60Hz.
