working xorg.conf file for Intel 845G Graphics
 
Hi All

After a couple of days with no success trying to get 3D acceleration on the Intel 845G graphics chip - yes, yes I have googled, searched forums, even used a working XF86Config-4 from a live-cd) I have just about had it. Consequently, I would be deeply appreciative if someone would post a working xorg.conf file or suggest a solution.

Relevant Details

OS: Slackware 10.2 Kernels 2.4.31, 2.6.12 (for slmodem) and 2.6.14.3

Chipset: Intel 82845
Graphics: Intel 845G
Driver used: i810

Depths tried 16 and 24

"dri", "glx", "GLcore" and host of other modules are "Loaded"

Thanks

Here's mine (for a 845GV mobo), works peachy in my FC4. Enjoy.

# RgbPath is the location of the RGB database.  Note, this is the name of the
# file minus the extension (like ".txt" or ".db").  There is normally
# no need to change the default.
# Multiple FontPath entries are allowed (they are concatenated together)
# By default, Red Hat 6.0 and later now use a font server independent of
# the X server to render fonts.

3D Acceleration on the Intel 845G graphics chip - Slackware 10.2
 
Thanks for the reply - however still no success. Incidentally, 3D acceleration works great on the same system using a llgp-0.1pre0 live-cd (based on Knoppix). For some reason though, I cannot get get the same result on Slack 10.2. I would be grateful for solutions from anyone who has had success with that distro and version using the Intel 845G chip and the i810 driver.

Cheers

When I had my Slack 10.2 and 11 I managed to get up 3d acceleration working by compiling the kernel with drivers for i810 and i915 ( As modules ).
After that I just added/changed into xorg.conf this:

Code:

# This loads the GLX module
    Load      "glx"
# This loads the DRI module
    Load      "dri"



Section "Device"
    Identifier  "Name of Monitor"
    Driver      "i810"
    VideoRam    65536
    Option    "XVideo"        "On"
    Option    "DevicePresence"    "On"   
EndSection


#At the end

Section "DRI"
    Mode 0666
EndSection

And everything was working fine.
I'm currently using Intel 845G with Slackware 12... But I haven't yet configured everything...

I hope this helps you!


Kind regards,
Steve
