Dual head mode with mouse and keybord isolate at one display

Fri Mar 2 06:07:28 PST 2007

Hi all,

I have been using dual head mode with sis driver, configured using the 
documentantion from [1] winischhofer. It is working with no problem, I 
have configurated the display 0.0 to use as computer (firefox, 
openoffice, tvtime, ...) and display 0.1 is using an svideo conected to 
a tv to watch dvds and videos.

Just one think is missing to be perfect, my mouse can move from one 
display to the other. How can I isolate the mouse and keybord to be 
isolated at display 0.0

I have looked fro multi terminals and xephyr, but I think it will be 
more robust solution if I could just configure it on Xorg.

Here are some informations about the enviroment:

Debian etch

# For Dual Head mode, a second "Device" section is required.
# The above "Device" section is for CRT2, while the following
# one is for CRT1. Note that not all options can be set in this
# second "Device" section. Options that determine settings
# which both heads need to know about are only allowed in the
# "Device" section for CRT2.
# Options that are allowed here are all "XvDefault...", all
# gamma correction and color related options and a few more.
# For example:

Section "Device"
     #VGA
     Identifier "Card-VGA"
     Driver "sis"
     BusID "PCI:1:0:0"

#   Option "XvDefaultAdaptor" "Blitter"

     Option "CRT2Gamma" "on"
     Option "EnableSiSCtrl" "true"
     # [sisctrl] Brightness/contrast for CRT2
     # In Dual Head mode, the options "Brightness" and
     # "Contrast" are preferred over "CRT2Brightness" and
     # "CRT2Contrast" (although both variants are accepted).

# Now for the real thing: Enable MergedFB mode -----------------

#   Option  "MergedFB" "true"

# Alternatively this can be done by

     Option "MergedFBAuto" "true"

# The difference between MergedFB and MergedFBAuto is that the driver,
# if the first of these options are set, will use CRT1 regardless if
# a monitor is detected or not. MergedFBAuto will cause the driver to
# use MergedFB mode if a monitor is detected, and to disable MergedFB
# mode if no monitor is detected. This is most convenient for notebooks.

# CRT2 should be left of CRT1
# This can be LeftOf, RightOf, Above, Below or Clone
# Default is RightOf

     Option  "CRT2Position" "LeftOf"

# MetaModes: Each mode-pair tells the server which modes to use on CRT1
# (left half of pair) and CRT2 (right half of pair). Modes given without
# being in a pair will be used on both heads whereas the image will be
# cloned. To use eg. 800x600 on both heads, but without cloning, use
# 800x600-800x600.
# If this option is not given, the largest mode for CRT1 will be merged
# with the largest mode for CRT2.

     Option  "MetaModes" "800x600+800x600"

# These define the capabilities of the CRT2 output device (eg. LCD, TV or
# secondary VGA). If CRT2 is LCD or TV, the driver will ignore these values.

     Option  "CRT2HSync" "30-71"
     Option  "CRT2VRefresh" "50-160"
