Since my update a couple of days ago, I haven't been able to get any accelerated OpenGL applications (read: games) to run. GLXgears still works, exactly the same as before, which seems unusual. Reproducible: Always Steps to Reproduce: 1. Run any accelerated OpenGL application (foobillard was my most common choice because it shows the error with the least fuss.) Actual Results: Message to console: Video mode set failed: X11 driver not configured with OpenGL Expected Results: Worked. :-) Upgrade was to opengl-update-1.8.1, which appears to behave differently to the previous versions so it's a top suspect. Same problem regardless of whether I use ati-drivers-3.2.8 or ati-drivers-3.9.0, so I think we can rule drivers out of the question. This is all I see in the Xorg.0.log file when it occurs, which doesn't seem related: GetModeLine - scrn: 0 clock: 202500 GetModeLine - hdsp: 1600 hbeg: 1664 hend: 1856 httl: 2160 vdsp: 1200 vbeg: 1201 vend: 1204 vttl: 1250 flags: 5 Of course dri and glx are both enabled in my X config, as they have always been, and even glxinfo shows them: name of display: :0.0 display: :0 screen: 0 direct rendering: Yes server glx vendor string: SGI server glx version string: 1.2 server glx extensions: GLX_ARB_multisample, GLX_EXT_visual_info, GLX_EXT_visual_rating, GLX_EXT_import_context, GLX_SGI_make_current_read, GLX_SGIS_multisample client glx vendor string: ATI client glx version string: 1.3 client glx extensions: GLX_EXT_visual_info, GLX_EXT_visual_rating, GLX_EXT_import_context, GLX_ARB_get_proc_address, GLX_ARB_multisample, GLX_ATI_pixel_format_float, GLX_ATI_render_texture GLX extensions: GLX_ARB_multisample, GLX_EXT_visual_info, GLX_EXT_visual_rating, GLX_EXT_import_context OpenGL vendor string: ATI Technologies Inc.

Solution found! I remerged libsdl and things worked again. Perhaps libsdl needs a version bump so that others don't run into the same problem.
Can't reproduce.
Oh well. Other people on the forums seemed to be able to.
I ran into this smae problem last night, and re-emerging libsdl initially did NOT work for me. Watching the output of the emerge, I noticed that the automake/autoconf script thought that OpenGL was NOT available on my system, though it most certainly is (e.g. glxgears and glxinfo indicate otherwise). I dug into the configure.log output and found that it failed to locate the GL/glxext.h header file, which now lives in a different location (x.org vs xfree86). I added a symlink in the /usr/include/GL directory, rebuilt libsdl, and everything is fine now. My /usr/include/GL directory now contains the following: $ ll /usr/include/GL total 100 -r--r--r-- 1 root root 7946 Mar 4 23:00 GLwDrawA.h -r--r--r-- 1 root root 4433 Mar 4 23:00 GLwDrawAP.h -r--r--r-- 1 root root 2309 Mar 4 23:00 GLwMDrawA.h -r--r--r-- 1 root root 2311 Mar 4 23:00 GLwMDrawAP.h lrwxrwxrwx 1 root root 37 Mar 4 23:00 gl.h -> /usr/lib/opengl/xorg-x11/include/gl.h lrwxr-xr-x 1 root root 38 Mar 15 19:33 glext.h -> /usr/lib/opengl/global/include/glext.h -r--r--r-- 1 root root 15981 Mar 4 23:00 glu.h -rw-r--r-- 1 root root 30192 Mar 3 07:20 glut.h -rw-r--r-- 1 root root 4109 Mar 3 07:20 glutf90.h lrwxrwxrwx 1 root root 38 Mar 4 23:00 glx.h -> /usr/lib/opengl/xorg-x11/include/glx.h lrwxr-xr-x 1 root root 39 Mar 15 21:09 glxext.h -> /usr/lib/opengl/global/include/glxext.h -r--r--r-- 1 root root 4257 Mar 4 23:00 glxint.h lrwxrwxrwx 1 root root 44 Mar 4 23:00 glxtokens.h -> /usr/lib/opengl/xorg-x11/include/glxtokens.h -r--r--r-- 1 root root 8349 Mar 4 23:00 osmesa.h I previously added the symlink for glx.h, too. I linked to the "global" rather than the xorg-x11 version since it seemed more up-to-date. Probably a potential source of pain, but it works. I'm not sure where the "global" headers came from-- maybe opengl-update? All of this should be handled by some other package, and should therefore be considered a bug in that package at this point; however, I'm not sure what package that is. Maybe x.org? Maybe opengl-update? Maybe something else? I dunno....
