Public bug reported:
Binary package hint: xserver-xorg-video-intel
Hardware:
~$ sudo dmidecode -s system-product-name
MacBook4,1
Linux: Ubuntu 8.10 RC
A dualhead configuration with xserver-xorg-video-intel 2:2.4.1-1ubuntu10
does not work. I have tested it with "gnome-display-properties", from
gnome 2.24.
I used three different xorg.conf, but none of them
lead to a real split screen configuration:
-----------------------------------------------------------------------
1.) The default xorg.conf after installation:
[CODE]
Section "Monitor"
Identifier "Configured Monitor"
EndSection
Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
EndSection
Section "Device"
Identifier "Configured Video Device"
EndSection
[\CODE]
If the external monitor is not plugged in,
the default conf will set the resolution to the native
value "1280x800".
If the external monitor is plugged in, it
will set the resolution to "1023x768" for both monitors
and clone the screen.
-----------------------------------------------------------------------
2.) The configuration from the gnome-display-properties tool:
[CODE]
Section "Monitor"
Identifier "Configured Monitor"
EndSection
Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
SubSection "Display"
Virtual 2048 768
EndSubSection
EndSection
Section "Device"
Identifier "Configured Video Device"
EndSection
[\CODE]
This works very buggy. The monitors have different resolution, but
its not possible to drag the mouse from one monitor to the other.
Also, the second monitor never gets a refresh, so all output
stays forever on the screen.
-----------------------------------------------------------------------
3.) I tried to write my own configuration:
[\CODE]
Section "Device"
Identifier "Configured Video Device1"
Screen 0
EndSection
Section "Monitor"
Identifier "Configured Monitor1"
EndSection
Section "Screen"
Identifier "Default Screen1"
Monitor "Configured Monitor1"
Device "Configured Video Device1"
EndSection
Section "Device"
Identifier "Configured Video Device2"
Screen 1
EndSection
Section "Monitor"
Identifier "Configured Monitor2"
EndSection
Section "Screen"
Identifier "Default Screen2"
Monitor "Configured Monitor2"
Device "Configured Video Device2"
EndSection
Section "ServerLayout"
Identifier "Default Layout"
# singlehead
#screen "Default Screen1"
# dualhead
screen 0 "Default Screen1" 0 0
screen 1 "Default Screen2" rightof "Default Screen1"
#Option "Xinerama" "On"
Option "Clone" "Off"
EndSection
[\CODE]
It didn't work with "screen 0" and "screen 1". It could only clone
the displays.
