The error I'd be most interested in looking at is the ones with

Xlib: extension "GLX" missing on display ":0.0".

Run the glxinfo command to see if it thinks direct rendering is enabled

$glxinfo
name of display: :0.0
display: :0  screen: 0
direct rendering: Yes
server glx vendor string: SGI
server glx version string: 1.2
<pile of other stuff>

If if says direct rendering: No then you'll need to set up DRI, a guide for which can be found here http://www.gentoo.org/doc/en/dri-howto.xml

Hope that helps,

and i did emerge X11 drm and got this error,

!!! ERROR: x11-base/x11-drm-20050502 failed.
!!! Function pkg_setup, Line 38, Exitcode 0
!!! Please set at least one video card in VIDEO_CARDS in make.conf or the environment. Possible VIDEO_CARDS values are: 3dfx ffb i810 i830 i915 mach64 matrox rage128 radeon savage sis via.

Well, from the looks of it,, you box doesn't even recognize you have GLX. Check your kernel for the vid card modules or some GLX stuff.

[kakariko81280]

The drm stuff has to be compiled to support particular video cards. The error in the second part of your last message would seem to be complaining that it doesn't know which card to target.

Which type of video card do you have? and if it is one of "3dfx ffb i810 i830 i915 mach64 matrox rage128 radeon savage sis via" then put it into your make.conf under VIDEO_CARDS, for example if you have a via card:

VIDEO_CARDS="via"

Check out http://gentoo-wiki.com/Unichrome for more details.

Once you have done that, try the emerge again and post any errors you get. If you don't have a supported card, or you aren't sure which option to choose tell us what kind of video card you have and we will try and help you out.

This is my card,

Identifier  "Card0"
        Driver      "nvidia"
        VendorName  "nVidia Corporation"
        BoardName   "NV34 [GeForce FX 5200]"
        BusID       "PCI:2:0:0"

And i get this whem i emerge X11 drm,

!!! ERROR: x11-base/x11-drm-20050502 failed.
!!! Function pkg_setup, Line 38, Exitcode 0
!!! Please set at least one video card in VIDEO_CARDS in make.conf or the environment. Possible VIDEO_CARDS values are: 3dfx ffb i810 i830 i915 mach64 matrox rage128 radeon savage sis via.

[kakariko81280]

Oops, the nVidia card would be the problem. Not a big problem, it just means we've been going about this the wrong way. nVidia provide closed source drivers so x11-drm can't be compiled for it.

Instructions for setting up nvidia-glx can be found here http://www.gentoo.org/doc/en/nvidia-guide.xml. These instructions are pretty comprehensive so I wont bother repeating them here.

Give them a shot and if you have any problems, post them here and we will try to help you out.

Let us know how you get on,

This has done the job thankyou,I recompiled my kernel and changed my xorg-conf following the instructions of the nvidia-glx-guide I had to configure a few settings but all seems good.
