Lines: 34 A while ago someone asked how to use multiple screen on color Suns. As far as I know, only the 'cgfour' graphic card supports this option. It has 9 bits per pixel - 8 per color and one for B/W. In my previous job I had a Sun-4/110 which also has two screens, like the 3/80. It was very simple: - for b/w apps, use DISPLAY=:0.0 - for color apps, use DISPLAY=:0.1 e.g: xterm -fn 9x15 -display localhost:0.1 & # color xterm window xterm -fn 9x15 -display localhost:0.0 & # b/w xterm window Moving the cursor to the rightmost/leftmost edges will toggle between the two screens. The real catch is how to bring up X11 so that you have two screens. - To have BOTH screens, you just say 'xinit'. - To have just color (in screen #0), you say: xinit -- -dev /dev/cgfour0 The above was true for X11R3, when color performance sucked. On X11R4, color performance was so much improved, so I never tried this tactic. BTW, both SunView and OpenWindows support this toggling, too. -- Amir J.
