When I run xinit, like normal, on a system with a color display instead of a B/W, it hangs and must be rebooted. However, if I run it and tell it to use the color display by name, it starts okay. So the problem seems to be in the auto-configuration code. I added a print statement to sunInit.c to tell me what displays it is finding, and get the following output when it is run on a Sun 3 with one display, a color display: bali% xinit -- Xsun Display 1: /dev/bwtwo0 Display 2: /dev/cgtwo0 It appears that the auto-configuration code is finding both a color and a b/w display on this machine, even though there is only one display. I believe the problem is that the color display has a b/w interface so that b/w applications can run on the color display. How do I determine that the b/w display is just a different interface to the color display and that I have only one display rather than two? jim
