ChromeOS, wine, gamma issues

[Tann]

This is probably a shot in the dark.................. but anyone else happen to be playing on a Chromebook using the built in ghetto-Linux? Got it setup running relatively smoothly but, even though the game is full screen in the wine virtual desktop, the gamma slider doesn't work and it's overly dark. Like so dark that infravision does nothing at night time, only ultravision provides a decent amount of night vision.

I think ChromeOS, being a browser type OS, doesn't let apps actually go full screen so not using a virtual desktop with winecfg doesn't work.
