Hello
Your pixel format patches caused a regression in half-life 1 for me with the fglrx drivers.
The same happend to me with opensource Intel drivers on a: $ lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation 82852/855GM Integrated Graphics Device (rev 02)
It refuses to start in opengl mode and reports "ChoosePixelFormat failed", and then comes up in software(ddraw) mode. The d3d mode still works fine. This problem also does not occur with the open source radeon driver. I tested with fglrx 8.28.8 and fglrx 8.27.10. Other games seem to work fine(appart of a few fglrx bugs)
Perfectly replicable on my system.
$ X -version X Window System Version 7.1.1
What infos do you need to debug this? This is the format table glxinfo reports:
$ glxinfo
