>the GL-enhanced parts of the xscreensaver suite are a very nice possibility to test those things, You might want to launch commands, like, "gears", "lament" or "atlantis" from Your next best xterm... If You then read an output, like "@@Created GLX Context@@" in the terminal where You started the application, it's likely that Your installed utah-glx is doing fine.
Thanks, I ran the demos, and they worked, with the exception of "lament": 08:49:55<~>$ lament @@Created GLX Context.. X error in lament: X Error of failed request: BadRequest (invalid request code or no such operation) Major opcode of failed request: 153 (GLX) Minor opcode of failed request: 145 () Serial number of failed request: 122 Current serial number in output stream: 122 I've just installed the new server (4.0.1) so it may be a server bug(??) Anyway, they do say "@@Created GLX Context.." and they run OK, though not as smoothly as, say, television or film. Also use up 65% of my cpu (Pentium III 500). I wonder if this is the best I can do with the current video card (ATI xpert 98, 8mb). If so, is it strictly a question of hardware limitations or are the drivers just not very good? -chris
