Gamma setting going down (0?) after monitor turnoff/when playing video

[MrDuck]

Hi here, last 3 days my xserver started to set gamma to very low value,so monitor is very dark,closely unreadable after resume from suspend mode or sometimes while playing video, looks a bit random, maybe sometimes even while just idle.
Probably it was around the time i added this into xorg.conf:

    Option   "Capabilities" "0x00000800"
    Option   "UseFastTLS" "off"
    Option   "KernelModuleParm" "locked-userpages=0"
    Option   "VideoOverlay" "off"
    Option   "OpenGLOverlay" "on"
    Option   "OverlayOnCRTC2" "1"
    Option   "FSAAScale" "0"
    Option   "FSAAEnable" "off"

Here is the whole xorg config:

Re: Gamma setting going down (0?) after monitor turnoff/when playing video

In your Section "Monitor" you might try adding a Gamma line for example:

Gamma 2.2

Re: Gamma setting going down (0?) after monitor turnoff/when playing video

Ok tried adding Gamma 2.2 (using 1,so 2.2 as u said to see change), however gamma in KDE kept at 1, so did it really change a thing? I'll see after few days, thx.
