centos 6.5 individuele desktops

[lazydave-II]

Default na de installatie van centos 6.5 krijg ik op een dualhead systeem een cinerama desktop. Dit is in mijn geval niet gewenst.. Dus in /etc/X11/xorg.conf.d een conf file aangemaakt met de volgende inhoud

code:

Section "ServerLayout"
        Identifier     "Multihead layout"
        Screen      0  "Screen0" LeftOf "Screen1"
        Screen      1  "Screen1" 0 0
        Option      "Xinerama" "off"
EndSection

Section "Screen"
        Identifier "Screen0"
        Device     "Videocard0"
        Monitor    "Monitor0"
        DefaultDepth     16
        SubSection "Display"
                Viewport   0 0
                Depth     16
                Modes    "1600x1200" "1280x1024"
        EndSubSection
EndSection

Section "Screen"
        Identifier "Screen1"
        Device     "Videocard1"
        Monitor    "Monitor1"
        DefaultDepth     16
        SubSection "Display"
                Viewport   0 0
                Depth     16
                Modes    "1600x1200" "1280x1024"
        EndSubSection
EndSection

en inderdaad krijg ik dan geen xinerama setup meer maar zijn de displays identiek... iemand een idee hoe ik naar de situatie kom dat ik weer 2 individuele displays :0.0 :0.1 kom?

Zonder enige informatie over hardware en driver in gebruik, geef ik je mijn nVidia config (volledige xorg.conf) met 2 aparte displays (waar de muis wel tussen kan bewegen, maar vensters niet):

Maar, dit had je in feite met Google of zelfs de Arch wiki (of desnoods die van Ubuntu) kunnen vinden.

Uiteindelijk is de enige regel die er toe doet degene die Xinerama op off (/false/no) zet in serverlayout. Maar het lijkt erop dat de autodetect setup de hotplug config in Rhel/centos wel leest maar alsnog xinerama aan zet.

Ik ga nu eens kijken helemaal zonder autodetect/hotplug en dus met een xorg.conf

Jammer dat xrandr (disper) niet gewoon een toggle voor xinerama heeft

essentieel is:
Option "ZaphodHeads" "HDMIx"
Option "AccelMethod" "sna"

waarbij HDMIx de naam is van de device die je terugkrijgt van Xrandr
