Gamma control - can't adjust. - Jusko - 11-07-2012


I have problem with Penumbra Collection. At first start there is gamma control to adjust brightness. The thing is, that it's not working. I can turn gamma to 0.1, but nothing happened - game is bright as it was (there is almost no need to turn on glowstick or flashlight, because i see near everything without it). Sure - I can adjust monitor gamma, but even when monitor gamma is set on almost maximum darkness, game still is too bright for me. Why I can't adjust gamma from game (maybe this settings are too deep in X to change by game)?

Distro: Fedora 17/18 x86_64.

What window manager are you using?

Have you tried switching to a *non* compositing window manager and see if it works then?

Well - I'm using GNOME3.

PS: I was experiencing this same thing on KDE4.


I've switched to GNOME Fallback and IceWM - on both this same issue.
