Xorg depth switch

I'm using 24bit color depth. When I switch to 16, I can't start X. It looks like white liquid in my screen.
my xorg:

Re: Xorg depth switch

uh, i don't know about that, but as said in update msg(when pacman installed your packages)     RgbPath      "/usr/share/X11/rgb"
should be deleted or commented out.. try doing that and see if you can startup then..

Re: Xorg depth switch

You have to add depth 16 to your display settings... change this

    SubSection "Display"
        Viewport    0    0
        Depth    24
    EndSubSection
EndSection

into this

    SubSection "Display"
        Viewport    0    0
        Depth    24 16 # <=here it is
    EndSubSection
EndSection

Stand back, intruder, or i'll blast you out of space! I am Klixon and I don't want any dealings with you human lifeforms. I'm a cyborg!

Re: Xorg depth switch

Still can't change it. First I saw that strange white liguid, I was afraid my display is broken smile
klixon:

    SubSection "Display"
        Viewport    0    0
        Depth    24 16 # <= this results to parsing error
    EndSubSection
EndSection

adding another SubSection or replacing 24 with 16 doesn't work.
test1000: I think it's not distro specific, because in mint it doesn't work either.

Maybe it's driver problem?

Re: Xorg depth switch

How is it possible that I can run X in 24bit depth and can't in 16bit depth? sad

Re: Xorg depth switch

Ati's proprietary drivers does support only 24bit depth.
http://ati.amd.com/products/catalyst/linux.html#9

Q9:        What colour modes are currently supported?
A9:     24-bit True Colour is currently the only native colour mode for the ATI Proprietary Linux Driver. 8-bit colour can be achieved using the pseudo-colour visuals feature, but may not work in all applications. 16-bit colour is not supported; if any of your critical applications require 16-bit colour, you should not install the ATI Proprietary Linux Driver.
