Steps: 1 - yum install x11vnc tigervnc xorg-x11-drv-sisvga 2 - From http://dev.laptop.org/~martin/usbvga/ grab xorg-xo1.5-dcon.conf - goes into /etc/X11/ olpc-usbvgamirror - goes into /usr/bin/ - mark it executable! 95-usbvga.rules - goes into /etc/udev/rules.d With all these elements in place, just plug the usb2vga device, and it'll mirror your XO screen. In case of trouble, output is logged in /var/log/vncmirror*.log . To tear the VNC sessions down, just unplug it. Known issues - It is slow and laggy. A VNC protocol expert may be able to help us optimise... - After a while, the client starts complaining of 'zero sized rect' - If you look carefully, the mirror session has a small square cursor in the middle of the screen. We need a variant on http://wiki.x.org/wiki/AdvancedTopicsFAQ#Iwanttomakethemousecursorinvisible but I could not make it work. Given how the technique works, I think vncviewer is overriding the root window cursor. - It consumes significant amount of CPU time... - You may want to disable aggressive suspend -- most of the time the CPU burn keeps the laptop awake. If it doesn't, you lose the device. cheers, m -- martin.langh...@gmail.com mar...@laptop.org -- School Server Architect - ask interesting questions - don't get distracted with shiny stuff - working code first - http://wiki.laptop.org/go/User:Martinlanghoff _______________________________________________ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
