quad-head display

here's how i set up a killer four-headed display with two networked laptops. use nvidia-settings to make a twinview display, external monitor above each laptop. i was a little worried about nvidia-settings clobbering my beautifully hand-edited xorg.conf with years of krufty commented-out lines. it does clobber, but i actually appreciate the clean up. i had to add the pan space to the metamode line manually, even though nvidia-settings has a box for it. from Option "metamodes" "CRT:nvidia-auto-select +0+0, DFP: nvidia-auto-select +0+1200" to Option "metamodes" "CRT:nvidia-auto-select @1920x1200 +0+0, DFP: nvidia-auto-select +0+1200" on the right and Option "metamodes" "CRT: 1280x1024 @1920x1024 +640+0, DFP: nvidia-auto-select +0+1200" on the left run x2x on the one on the right with this script: #!/bin/bash # creates a connection to an x server physically located to the left ssh -X otherlaptopname "x2x -west -to:0." EDIT: i've found that panning the smaller screen is more hassle than it's worth, especially when switching the second monitor on and off without restarting x. so now i have Option "metamodes" "CRT:nvidia-auto-select +0+0, DFP: nvidia-auto-select +0+1200" on the right and Option "metamodes" "CRT: 1280x1024 +0+0, DFP: nvidia-auto-select +0+1200" on the left
