How do I select a default visual

[Kotaru, Raj]

I am running Fedora 14 on a HP PC.  The video is "Intel Corporation
82Q963/Q965 Integrated Graphics Controller".

I need to run a legacy application that requires an 8 bit Pseudocolor
default visual.   It uses overlay visuals and requires a writable color
map.

I edited "xorg.conf" as follows:

 

Output of Xdpyinfo gives me an 8 bit pseudocolor visual, but this is not
the default.  Is there an option that lets me choose the default visual?

 

Thanks

Raj

 

 

Xorg.conf sample:

 

Section "Device"

        Identifier  "Card0"

        Driver      "intel"

        BusID       "PCI:0:2:0"

EndSection

 

Section "Screen"

        Identifier "Screen0"

        Device     "Card0"

        Monitor    "Monitor0"

 

        DefaultDepth    8

 

        SubSection "Display"

                Viewport   0 0

                Depth     8

                Visual    "PseudoColor"

        EndSubSection

EndSection
