Comment 85 for bug 362582

I tested the ns2501 patch that Gilles Dartiguelongue wrote and it works on my Fujitsu Siemens S6010 Lifebook! Thank you very much Gilles! This is very good progress finally! I hope we can figure out why it does not work on your laptop and to improve the patch to have it included upstream.

This is my recipe for compiling Gilles Dartiguelongues patch on Fedora
12 with kernel 2.6.32.10-90.fc12.i686.

The last version which contains the directories for Gilles patch is
xf86-video-intel-2.9.1. Later versions of the Intel driver require
kernel mode setting, so the patch cannot be applied since the directories have been moved.

Get the source of xf86-video-intel-2.9.1 with
wget http://ftp.x.org/pub/individual/driver/xf86-video-intel-2.9.1.tar.gz
tar -xvzf xf86-video-intel-2.9.1.tar.gz
cp -ax xf86-video-intel-2.9.1 b

Apply Gilles patch

patch -p0 -i 0001-Initial-support-for-NS2501-LVDS-driving-chip.patch
cd b

On Fedora 12 I had to make the following changes in ns2501.c to Gilles
patch in order to make it compile
comment out
  #include "xf86Resources.h"
replace
  #include <X11/extensions/dpms.h>
with
  #include <X11/extensions/dpmsconst.h>
  #include <X11/extensions/dpmsproto.h>

Compile the modules with:
  autoconf
On Fedora 12 I get an error message about the version of automake so I
need to run
  autoreconf
  ./configure --prefix=/tmp/intel-test
  make
  make install

Then the new modules need to be taken into use
cp /tmp/lib/xorg/modules/drivers/ns2501.so /usr/lib/xorg/modules/drivers/
mv /usr/lib/xorg/modules/drivers/intel_drv.so /usr/lib/xorg/modules/drivers/intel_drv.so_F12_org
cp /tmp/lib/xorg/modules/drivers/intel_drv.so /usr/lib/xorg/modules/drivers/

With these changes X starts with the intel driver. Glxgears works, but etracer crashes X. Also the beta version of the EVO videoconferencing system uses 3D-graphics which crashes X11.

The output from xrandr is strange since it claims that both outputs are disconnected, while in fact the LVDS does work.

xrandr -q
