I'm running an intel i810 motherboard, with no extra cards, have complied a gentoo kernel with what i think are all the relevant options includin agpart and dri support. No framebuffer.

Without the glx module running in xorg, everything runs fine, XFce looks exactly like it should. Then i added glx support. GLX works fine as far as i can tell, all the GL screensavers work...

BUT every window in XFce4 now grows a black square in the bottom corners and depending on the theme, other parts of the window get black rectangles. Most obvious is the b6 theme, which if you've not seen, is one of the themes that has a variabley sized tab at the top of the window, that doesn't go all the way along, and a smaller thinnner tab that does. The area between the extremeties of the larger tag and the window, that would usually be totally transparrent are now also ugly balck rectangles.

I will provide a screen shot if someone will tell me how.

please help

Hello mr666white !
If You please, go and edit /etx/X11/xorg.conf. In section "Module" check if there is line:
Load "extmod"
If not, there add it and save Your changes.
It should help You.

Best regards
Paul M.

of you have Load glx uncommented Load Dri should be commented.

Fixed and forgotten about. Permissions for DRI were not set correctly (ie the permissions line was commented out. I set to 660 and it was happy.
