3D Acceleration

cccc · 10-29-2009, 09:26 PM

hi

I've installed Lenny with Gnome on the Desktop DELL Optiplex GX270 with the graphic card Intel(R) 82865G.
Video Drivers were installed automatically, but the 3D Acceleration doesn't work.
Howto enable 3D Acceleration for this graphic card?

You have the Debian drivers. These work OK in 2D, but for 3D you'd need the Intel drivers. Google is your friend

well: its weird stuff for me, so take this just as ideas:
xserver-xorg-video-intel should have come with a gnome-install, though im not sure if its the one for your card.

you still got a /etc/X11/xorg.conf ? how does it look like?:
video driver is set to intel ?

Code:

Section "Extensions"
        Option  "Composite"     "Enable"
EndSection

AccelMedthod is what, UXA? , <load dbe> is enabled?
you got mesa-utils installed ?
i allways run < glxinfo | grep direct >, you might run the compiz-check:
http://forlong.blogage.de/entries/pages/Compiz-Check,
or <compiz -replace & > from a cli to get some error-messages.

what do you need 3d for, compiz?

as said: thats the (confused) way i go if fiddling with 3D and that. good luck

my /etc/X11/xorg.conf

as said: i sure dont know much bout such stuff. that said:
a while ago a fellow user posted a xorg.conf over here. he said it would have never failed on him when running on intel. I copied and pasted it and made tiny changes. Keyboard-layout is set to german (de). if you got a different dont forget to change that :-)
Here it is:

Code:

         Option "DontZap" "off"
         Option "AllowEmptyInput" "0"
         Option "AutoAddDevices" "0"

The main parts for getting compiz running are:
load dbe # in Section Module
Option "XAANoOffscreenPixmaps" "true" #Seciton device
Option "AllowGLXWithComposite" "true" #Section device
AccelMethod "UXA" #Section device
and adding this complete Section
Section "Extensions"
Option "Composite" "Enable"
EndSection

Im pretty sure you may comment out the last section "ServerFlags" and
Option "XkbOptions" "terminate:ctrl_alt_bksp"
in the Section "InputDevice" as that "problem" might not exist in lenny.

run

Code:

glxinfo | grep direct

to check if direct renering is enabled.
all afaik, good luck

Code:

# glxinfo | grep direct
# direct rendering: Yes

well: looks good, or not?
have you tried the xorg.conf i posted? i used it on different setups and it worked fine.

you asked over at debian.forums for how to configure xorg. im not sure if it still works in lenny, but you may try:
Xorg -configure
from a terminal (either single-user or without login-manager)
which will create an xorg.conf in /root
(might be it looks like the one you allready got, i cant remember).
well, someone will be able to tell you for sure over there.
