here comes some [surprising?] news

ati cards can do 3d with xorg 1.10 and kde4

I have the same ports versions as Warren provided earlier, everything
according to xorg-server 1.10 from actual ports tree with WITH_NEW_XORG
in make.conf



after playing with xorg settings, from glxinfo I saw some times instead
of Rasterizing:

Error: couldn't find RGB GLX visual or fbconfig

was motivated me to recompile ligBL, libdrm and dri one-by-one

surprisingly I got then

OpenGL renderer string:
	Mesa DRI R600 (RV610 94C3) x86/MMX+/3DNow!+/SSE2 TCL


even if all dependencies were ok before and pkg_libchk did report
nothing wrong, something must have been wrong

but then I got the same mess on another machine, my eventual fast
conclusion is that libGL and lidrm must be compiled after xorg-server
upgrade


anyway ... so now I have 3D?

but not quite

after trying several xorg.conf settings, with recommended settings and
no xorg.conf at all, I ever saw this

[ 14699.367] (II) LoadModule: "glx"
[ 14699.368] (II) Loading /usr/local/lib/xorg/modules/extensions/libglx.so
[ 14699.371] (II) Module glx: vendor="X.Org Foundation"
[ 14699.371]    compiled for 1.10.6, module version = 1.0.0
[ 14699.371]    ABI class: X.Org Server Extension, version 5.0
[ 14699.371] (==) AIGLX disabled
[ 14699.371] (II) Loading extension GLX

after some tries I configured this in xorg


Section "Device"
    Identifier  "CARTAO"
    Driver      "radeon"
    Option      "Monitor-VGA-0" "LEFT"
    Option      "Monitor-DVI-0" "RIGHT"
EndSection

Section "ServerLayout"
    Identifier     "DHEAD"
    Screen         "VGA-Left"
    Screen         "RIGHT" RightOf "LEFT"
    Option         "AIGLX" "on"
EndSection

no section for modules, no extension and flags and I now get this

[    37.140] (II) LoadModule: "glx"
[    37.141] (II) Loading /usr/local/lib/xorg/modules/extensions/libglx.so
[    37.162] (II) Module glx: vendor="X.Org Foundation"
[    37.162]    compiled for 1.10.6, module version = 1.0.0
[    37.162]    ABI class: X.Org Server Extension, version 5.0
[    37.350] (**) AIGLX enabled


even is it not relevant but as test, it runs perfect and stable the cube
... in all directions over both monitors, nice :)


I still had a minor setback, xorg crashed always when a modal window
"glided" in

first I thought no problem, I can do without, then I saw it on another
machine working flawless

after removing the whole ~/.kde4 which came from kde4.7 I got it stable
on my login

some test on other machines showed that there also the problem existed,
so who upgraded from kde4.7 to 4.8 could have some crap leftover in
~/.kde4 which cause xorg to crash

I hope this can be helpfull for somebody somewhere ...
