Using AppleSGLX-55 and xorg-server-1.4.2-apple37 from macports, I can now compile a working X-server with accelerated OpenGL on Tiger. The only difference I noted compared to the system X11 is that a glx program which tries to use a stereo visual crashes. I can replicate the same crash with glxgears -stereo:
env LIBGL_DIAGNOSTIC=1 glxgears -stereo initializing libGL in apple_init_glx DIAG: CGL major 1 minor 0 error: invalid pixel format X Error of failed request: GLXBadContext Major opcode of failed request: 0 () Serial number of failed request: 22 Current serial number in output stream: 22
So far, this is the only problem that I have experienced with xorg- server-1.4.2-apple37 on Tiger. Thanks for the Tiger support, Martin
