The GL extension GL_EXT_texture_sRGB defines the texture formats GL_SRGB and friends and specifies that sampling such a texture automatically converts the values from non-linear RGB (sRGB) to linear RGB.
However, this conversion is not performed on my system; the textures seem to be sampled as if they were normal GL_RGB textures. This results in wrong colors (e.g. in the git version of the Bino 3D video player: far too bright).
I'm running Ubuntu 10.10 on x86_64 and get the following version info from GL:
OpenGL version: 2.1 Mesa 7.9-devel
OpenGL renderer: Mesa DRI R600 (RV710 954F) 20090101 TCL DRI2
OpenGL vendor: Advanced Micro Devices, Inc.
If you need more information, please let me know.
Note: classic r600 driver has been abandoned.
Please use r600g (gallium driver) instead.
It should handle GL_EXT_texture_sRGB correctly.
