When I try to run any openGL program in X it boots me back to the login screen... any sugestions... I''m useing Mandrake 8.2 with XFee86 4.2.0 with acceleration on a voodoo 3 vid card... the monitor and vid card settings seem to be correct.. --Jabin Tangeman http://bsu.homeip.net

It sounds like X is crashing and xdm/kdm/gdm is restarting it. You probably have something setup incorrectly (or something not at all). However, I''m not expert with Voodoo cards, so I can''t tell you what; sorry. At least I''m bumping you back up so that someone else can give it a try .

I had this problem when I was trying to switch OpenGL contexts between threads incorrectly. It crashed in glXMakeCurrent() or in glXSwapBuffers(). You may want to run your app with a debugger (from commandline ) to see where exactly it happens.

Have a nice day,

I run it in the debugger and it Segmentaion Faults when Glut tries to init the display... opening libGL.so.1.2, however I have another program that works fine and also uses glut and the same display mode so I''m really confuesed...

I had the same problems a while ago, but that''s when I booted the OS in run-level 5. Try changing to run-level 3. When it boots into the console, type startx. See if that helps.
