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.

Code:
Section "ServerLayout"
	Identifier     "Default Layout"
	Screen      0  "Screen0" 0 0
	InputDevice    "Mouse0" "CorePointer"
	InputDevice    "Keyboard0" "CoreKeyboard"
EndSection

Section "Files"

# 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.
	RgbPath      "/usr/X11R6/lib/X11/rgb"
	FontPath     "unix/:7100"
EndSection

Section "Module"
	Load  "dbe"

	Load  "fbdevhw"

Section "InputDevice"

# Specify which keyboard LEDs can be user-controlled (eg, with xset(1))
#	Option	"Xleds"		"1 2 3"
# To disable the XKEYBOARD extension, uncomment XkbDisable.
#	Option	"XkbDisable"
# To customise the XKB settings to suit your keyboard, modify the
# lines below (which are the defaults).  For example, for a non-U.S.
# keyboard, you will probably want to use:
#	Option	"XkbModel"	"pc102"
# If you have a US Microsoft Natural keyboard, you can use:
#	Option	"XkbModel"	"microsoft"
#
# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:
#	Option	"XkbLayout"	"de"
# or:
#	Option	"XkbLayout"	"de"
#	Option	"XkbVariant"	"nodeadkeys"
#
# If you'd like to switch the positions of your capslock and
# control keys, use:
#	Option	"XkbOptions"	"ctrl:swapcaps"
# Or if you just want both to be control, use:
#	Option	"XkbOptions"	"ctrl:nocaps"

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
