Hi again, to repeat my earlier mail, I'm working on a small compositing wm for funsies, and I've again run into an issue. I'm using as my guide what's in compiz as well as the usage example near the bottom of this page: http://people.freedesktop.org/~davidr/GLX_EXT_texture_from_pixmap.txt First problem: the below snippit returns 0 configurations: const int fb_attrs[] = { GLX_DRAWABLE, GLX_PIXMAP_BIT, None }; fb_configs = glXChooseFBConfig(dpy, screen_num, fb_attrs, &n_configs); // n_configs now equals 0 :( Does that mean I'm somehow missing GLX Pixmap support? do I need it? (I notice compiz doesn't appear to check for it) Next problem: If instead of the above I just iterate through all of the configs using glXGetFBConfigs, none of the configurations support GLX_BIND_TO_TEXTURE_TARGETS_EXT (glXGetFBConfigAttrib returns 0 for all of the configs). Is this needed? I tried ignoring this and used GL_TEXTURE_2D rather than GLX_TEXTURE_2D_EXT (and GLX_TEXTURE_RECTANGLE_BIT_EXT) but I end up with just a white texture... If I do try and use either of the EXT targets my machine hardlocks :( _______________________________________________ xorg mailing list xorg@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/xorg
