The person at Sun who suggested this should be shot (well, at least corrected) because a) there is no need for a /dev/cgsix0 device (/dev/fb works just fine) and b) there is such a thing as a multi-headed system you know! Probably the best way to do this is to get a file descriptor pointing to the frame buffer device and then use the FBIOGATTR ioctl. For example, in a SunView program you might do something like... int fd; struct screen screen; struct fbgattr fbattr; win_screenget((int) window_get(win, WIN_FD), &screen); if ((fd = open(screen.scr_fbname, 2, 0)) < 0) { /* error */ } if (ioctl(fd, FBIOGATTR, &fbattr) < 0 || fbattr.fbtype.fb_type != FBTYPE_SUNFAST_COLOR) { /* it's not a cg6 */ } else { /* it is a cg6 */ } (void) close(fd); David DiGiacomo, Sun Microsystems, Mt.

I am running the only SS1+/GX on the local network, which means that the recently delivered copy of Aviator can only run stand-alone (since Aviator seems to poll for the GX hardware directly as the code describes). I also have a 3/260 with what I believe is a cgsix installed, but is now running as a cgtwo - see startup message. mcp0 at vme32d32 0x1000000 vec 0x8b ie0 at obio 0xc0000 pri 3 cgtwo0 at vme24d16 0x400000 vec 0xa8 cgtwo0: Sun-3 color board, double buffered, fast read root on xd0a fstype 4.2 The GENERIC kernel doesn't help as it only shows how to run a cgsix in a 3/60 (obmem 7). Needless to say aviator doesn't think this is the right board to talk to. Can someone tell me how to config it properly as a cgsix, and whether the code would detect it as being such (under 4.0.3)? And, can a 3/260 run the aviator demo at a reasonable speed? Randolf Klatt Westinghouse Electric ittc!rklatt@uunet.uu.net P.S. This is purley a spare-time pursuit, you understand...
