Subject: Настройка XOrg для работы с несколькими мониторами
Оригинал: http://blog.chris.tylers.info/index.php?/archives/14-Multiseat-X-Under-X11R6.97.0.html
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 http://x.org) - FC5 test releases include 6.9.
3. Configure and test a Xinerama configuration using "X -configure".
(Refer to http://www.tldp.org/HOWTO/Xinerama-HOWTO/ 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!
