I'm curious if anyone else has experienced this and if it needs
reporting someplace.
I've been running Xinerama on a Matrox G550 for a few years. With
this last xorg upgrade from 6.8.2 to 7.0.0 there were a few odd
things.
My card has two outputs -- one VGA and one DVI. When I boot the VGA
is the main display (the DVI display is off until I start X).
After upgrading to 7, now when I startx the DVI display seems like the
"main" display, in that's where my window manager starts. I could not
correct this in xorg.conf, and had to physically swap my cables to get
xinerama to work correctly. Now my right hand monitor is the monitor
used when not running X, which is not really what I want.
I tried a bunch of different configurations but could not get it back
to how it used to be, with the left monitor being connected to the
VGA port and used as the main monitor for both console mode and when
X was running.
The other problem is after a reboot only one monitor starts. The DVI
interface monitor stays in power save mode when X starts. But, I've
found a trick to get it to start:
This is is my layout:
Section "ServerLayout"
Identifier "Default Layout"
Option "Xinerama" "on"
Screen 0 "LeftScreen" 0 0
Screen 1 "RightScreen" RightOf "LeftScreen"
InputDevice "Generic Keyboard"
InputDevice "Configured Mouse"
EndSection
The only way I've been able to get both monitors to start is to
comment out Xinerama and my "right" screen. Then the left monitor
(the DVI connected one) will come out of dpms mode. That is:
Section "ServerLayout"
Identifier "Default Layout"
#Option "Xinerama" "on"
Screen 0 "LeftScreen" 0 0
#Screen 1 "RightScreen" RightOf "LeftScreen"
InputDevice "Generic Keyboard"
InputDevice "Configured Mouse"
EndSection
Then I exit X and remove the comments then I can restart X and then
both monitors will start.
Anyone else having problems with getting Xinerama started or with the
left/right monitor configuration?
