Hi.

As the title says, adjusting the gamma has no effect, be it using F11 or the menu.

Operating system: Arch linux 32 bit
Graphics card: 00:02.0 VGA compatible controller: Intel Corporation Mobile GME965/GLE960 Integrated Graphics Controller (rev 0c)
Intel graphics driver version: 2.12.0
Xorg version: 1.8.1.902
GZDoom compiled from source using this PKGBUILD: http://aur.archlinux.org/packages/gzdoo ... m/PKGBUILD

Hmm, that's interesting. The svn checkout command said "Updated to revision 864" but gzdoom says "GZDoom v1.4.8 - SVN revision 763M - SDL version". Is that normal?

The repository is currently at r864. However, your PKGBUILD thingie does not seem to take from the trunk, but from a tag: If you look at the repository, you'll see that r763 does correspond to the version for the tag.

Try replacing the line above by this: and I suppose that it should then let you build the current revision.

Thanks for clearing that up. I did as you suggested and now I have revision 864. However, the gamma correction problem persists.

To be clear, how are you trying to change the gamma? I am hitting F11 and it correctly bumps the gamma for me.

I tried hitting F11 - I see the messages at the top of the screen "gamma correction level ...." but the image does not change at all.

I also tried the slider in the menu, with similar results.

The slider and the key both do the same thing -- they change the same variable. If one fails, the other should fail too.

I wonder if this could be somewhat similar to this old thing, in that a system driver interferes and prevents the application from changing the gamma.

I'm currently "seeing" this bug behaviour too.
I use Linux and have a nvidia card.

It's not the card because I just bought an asus engtx470 and it also appears to have the same issue. (No I did not buy this card just because of this bug )
It started occurring with the nvidia drivers hitting 256 I guess.

Intel GME965

and

Linux

Sound like a driver bug to me.

Can it be a driver bug if xgamma works? I was able to change the gamma just fine with that.

No idea how xgamma works. The gamma functionality depends on SDL being able to communicate with your hardware and both components are outside my control.
