Summary: Gamma values are messed up in 16 bit mode
Product: xorg
Version: 7.4
Platform: x86 (IA32)
OS/Version: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Driver/Radeon
AssignedTo: xorg-driver-ati@lists.x.org
ReportedBy: sm...@kip.uni-heidelberg.de
QAContact: xorg-t...@lists.x.org
If i specify "DefaultColorDepth 16" in the "Screen" section in xorg.conf, The
Image is all greenish and rather dark.
My graphics card is a "Radeon Mobility 9200 (AGP)" with only 32MB of video
memory. So I can not use the full 1920x1200 resolution of my Monitor with 24
bit. 16 bit used to work but after an update (I run gentoo linux and have now
installed the package xf86-video-ati-6.12.6 and x11-base/xorg-x11-7.4-r1)
After patching "xf86-video-ati-6.12.6/src/radeon_crtc.c" as described in a
similar bug report here:
https://bugzilla.redhat.com/show_bug.cgi?id=554967
the problem is solved.
But maybe somebody wrote this code that now is no longer executed for a
purpose?
