That was a very hard one: The BIOS says that 1400x1050 is not supported, so XFree doesn't recognize this as a possible resolution. The solution came with a tool called 855resolution, wich can be found at http://perso.wanadoo.fr/apoirier/. This patches the BIOS everytime the X display manager is started (patch is not permanent). All you need to do is:
855resolution 5a 1400 1050
and all works. I embedded this in the xdm start script at
/etc/init.d/xdm
:
start() { setup_dm # run 855-script for intel graphics card in full 1400x1050 /scripts/855 # set the cpu to the right speed /scripts/switchspeed ...
The /scripts/855
just contains the
855resolution call. Another thing you see
here is the switchspeed script which changes
sets the CPU speed for battery and cable differently on boot.
Parts of my /etc/X11/XF86Config
looks like
this:

The XFree mentioned above has been replaced with an X.org 6.8.2 server. All future documentation will refer to this one.
X.org provides a driver for Intel based graphics chipsets, the
i810
. Unfortunately, glxgears is somehow slow
(around 600fps), and I wanted to replace the X.org driver (which are
generally built for stability) with the one Intel provides on its
website.
They have two files for the driver:
dri-I915-v1.1-20041217.i386.rpm
i915Graphics.tar.gz
The first one didn't install, but as I don't like rpms on a
Gentoo box, I tried the driver compilation via the
install.sh
script in the tar.gz driver package.
It has a menu which guides you through the installation process.
However, compilation failed with the message:
Compiling new agpgart module... Compiling DRM module... ERROR: Kernel modules did not compile
The dri.log
then contained the following
lines:
make -f Makefile.linux DRM_MODULES=gdg.ko modules make[1]: Entering directory `/data/download/intel855/dripkg/drm' make -C /lib/modules/2.6.13/build SUBDIRS=`pwd` DRMSRCDIR=`pwd` modules make[2]: Entering directory `/usr/src/linux-2.6.13' CC [M] /data/download/intel855/dripkg/drm/gdg_drv.o In file included from /data/download/intel855/dripkg/drm/gdg_drv.c:17: /data/download/intel855/dripkg/drm/drm_agpsupport.h:47: error: syntax error before '*' token ... (usual stuff which follows the first error)
I wrote to Intel support asking for help or an updated driver. The answer came one day later:
“The support we provide for Linux* is limited to providing drivers. For assistance in other support topics, please contact your Linux* vendor.”
They are telling me that they provide drivers, and if they don't work it's my problem? If they really mean this seriously, Intel just lost a customer.
