I walked into the office of a friend and noticed that he had two screens off of a Sun, one color, one mono. The problem was that when he moved the cursor out of the color screen it changed to the usual blanked background. I think this might be happening because he has a cgfour device and it is detecting the cursor moving off the color screen and switching the color screen to mono. I looked at the server options to see if this 'feature' could be disabled but nothing was obvious. Anyone know how to do this ? Thanks, Paul. -- Paul O.

The problem was that when he moved the cursor out of the color screen it changed to the usual blanked background. The problem is that there is a third desktop there, a bwtwo1, which doesn't appear in the sunInit.c file (in mit/server/ddx/sun/) ... put this in, get the patches for multi-screen support, rebuild the server, and your friend will have three desktops (which would actually obviate the need for the second monitor, but what the heck?). Some 3/60s that have a cgfour as an add-on (rather than stock) wind up having the 10th plane be bwtwo1 ... I used to just MAKEDEV bwtwo1 and mv(1) it to bwtwo0 to get the two-screen hack to work, since it open(2)s the file in /dev rather than figuring it out from /dev/fb ... /jordan
