[1.4.08 (svn rev 864)] adjusting gamma has no effect

[cantabile]

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:

Code: Select all

_pkg_svntrunk="http://mancubus.net/svn/hosted/gzdoom/tags/${pkgver}/"

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:

Code: Select all

_pkg_svntrunk="http://mancubus.net/svn/hosted/gzdoom/trunk/"

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.

[Gez]

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.

[cantabile]

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

[Graf Zahl]

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.
