When GLUT creates a window it uses glXChooseVisual(). That function prefers TrueColor visuals over DirectColor visuals, all other things being equal. So, GLUT programs can't specifically request a DirectColor visual. >>Maybe I don't quite understand what the problem is. > > > I run the X-server with "default" visual DirectColor (see xdpyinfo below) > The colours of the gears program turn out to be wrong in this case.

That's what usually happens when you have windows with different colormaps and your hardware really only has one colormap. That said, if your DirectColor windows are using the standard color ramps, like a TrueColor visual, you shouldn't see flashing since the two colormaps should be equivalent. You might want to try the hack I put into GLUT last week. If you set the GLUT_FORCE_VISUAL env var to 33 you should get a GLUT window with the DirectColor visual. -Brian ------------------------------------------------------------------------- Take Surveys.
