From: Chris Tyler <>; Date: Sun, 19 Nov 2006 17:02:14 +0000 (UTC) Subject: Настройка XOrg для работы с несколькими мониторами Оригинал: Ниже показано как настроить работу нескольких мониторов, видеокарт, звуковых карт, клавиатур и мышей для создания нескольких рабочих мест на базе одного физического компьютера. Multiseat X Under X11R6.9/7.0 I keep getting inquiries about multiseat X configuration under X11R6.9. Here is a temporary mini-Howto document that I've put together. I'll write a better one when X11R6.9/7.0 is finalized (and time permits :-) ) ... and there will be a chapter on the topic in one of my upcoming books. In the meantime, have fun! -- please let me know what experiences you have trying this out (positive or negative) -- in particular, it would be great to have reports on which video card combinations work or do not work. (For those new the term "Multiseat X", it means creating a system with mulitple video monitors, keyboards, and mice for simultaneous use by multiple users -- like my home system). Warning! This isn't a project for the faint-of-heart! It requires good sysadmin expertise and lots of patience. If you want a simple[r] solution, please contact me in the Spring of 2006 to inquire about configuration scripts to automate some of this setup. Hardware requirements - Compatible AGP/PCI/PCIE video cards. The definition of "Compatible" is very much up in the air at this time. Chipsets from the same manufacturer often work well. If you're using nVidia cards, use the non-GPL "nvidia" driver instead of the GPL "nv" driver. - Zero or one PS/2 keyboard and mouse sets, and one or more USB keyboard and mouse sets. - Zero or more sound cards. Directing the sound output from each application to the correct speaker set is left as an exercise for the reader. 1. Install your favorite distro. 2. Upgrade the X server to X.Org 6.9 if necessary (pre-release versions at - FC5 test releases include 6.9. 3. Configure and test a Xinerama configuration using "X -configure". (Refer to if needed) 4. Plug in your additional USB keyboards and mice. 5. Find all of the keyboards and mice in /proc/bus/input/devices. Note the Handlers line for each device; find the 'eventX' value for each keyboard and the 'mouseX' value for each mouse. 6. Construct an InputDevice section for each keyboard, and place it in the /etc/X11/xorg.conf file: Section "InputDevice" Identifier "keyboardN" Driver "evdev" Option "Device" "/dev/input/eventX" EndSection Replace N with a sequential keyboard number, and X with the event handler identified in step 5. 7. Construct an InputDevice section for each mouse, and place it in the /etc/X11/xorg.conf file: Section "InputDevice" Identifier "mouseN" Driver "mouse" Option "ZAxisMapping" "4 5" Option "Device" "/dev/input/mouseX" EndSection Replace N with the a sequential mouse number, and X with the mouse handler identified in step 5. 8. Create a ServerLayout section for each seat, and add it to the xorg.conf file: Section "ServerLayout" Identifier "seatN" Screen 0 "Screen0" 0 0 InputDevice "mouseN" "CorePointer" InputDevice "keybaordN" "CoreKeyboard" EndSection 9. Test the displays using the -novtswitch and -sharevts options: X -novtswitch -sharevts -layout seatN :0 Replace N with each seat number in turn. You probably won't be able to zap (Ctrl-Alt-Backspace) the server nor switch VTs, so you'll need another system with ssh access to terminate the X servers (or run something like 'while sleep 60 ; do killall X ; done' in the background). 10. Add the new X servers to the display manager configuration. If you're using Fedora Core, for example, modify /etc/X11/gdm/gdm.conf: - Comment out this line by prepening the #: #0=Standard - Add these lines, one for each seat: 0=Standard0 1=Standard1 ... - Add these sections: [server-Standard0] name=Standard server command=/usr/X11R6/bin/X0 -novtswitch -sharevts -layout seat0 flexible=false [server-Standard1] name=Standard server command=/usr/X11R6/bin/X1 -novtswitch -sharevts -layout seat1 flexible=false 11. Restart the display manager and enjoy!
