TODO
This page needs to be merged with the Extreme Graphics page, because these two video adapters are actually the same. Other than a slower clock speed, and a different PCI ID.

Intel Graphics Technology

This is an Intel video adapter.

Features

  • Integrated in the Intel 82830MG northbridge.
  • PCI ID: 8086:3577
  • Dynamically allocates available RAM to video memory (8MB to 64MB)

Linux X.Org driver

This chip is supported by the 'i810' or 'intel' driver as part of the X.Org distribution. You should also have intel agp and drm enabled in kernel: 

CONFIG_AGP=m                                                                                        
CONFIG_AGP_INTEL=m                                                                                  
CONFIG_DRM=m                                                                                        
CONFIG_DRM_I915=m

Use xf86-video-intel-2.1.0 or greater (2.0.0 has a bug). For dual-head you should set big enough area in xorg.conf: (2048 2048 max) 

Section "Screen"                                                                                   
(..)
   Subsection "Display"                                                                            
(..)
       Virtual 2048 768                                                                                    
   EndSubsection                                                                                   
EndSection

Then you should setup your displays by hand or by adding to the end of /etc/X11/xinit/xinitrc (just before starting window manager, btw. multi head wm recommended, fluxbox works fine): 

xrandr --output LVDS --auto --pos 0x0 --left-of VGA

ThinkPad LCD

Display on the internal LCD works as long as you set the monitor settings correct.

External VGA port

Works. Dualhead supported (see above).

SVideo port

Not available.

DVI port

Not available.

Linux kernel Framebuffer driver

This chip will work with either the 'vesa' or 'intelfb' driver as part of any recent 2.4 or 2.6 kernel.
