I install the latest version of the kernel:
# apt-get install linux-headers-2.6.38-1-amd64
# apt-get install linux-image-2.6.38-1-amd64I install the latest versions of the xorg components from the unstable branch. (All the components until no dependency is missing)
# apt-get install -t unstable xserver-xorg-input-synaptics xorg xserver-xorgI see that there are related bugs in the Debian bugtracker: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=597082 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=572842
The first of them refers to this patch and we download it to /usr/src/99-clickpad.patch: http://bugs.debian.org/cgi-bin/bugreport.cgi?msg=26;filename=99-clickpad.patch;att=1;bug=597082
We download the sources from Debian unstable for xserver-xorg-input-synaptics:
# apt-get source -t unstable xserver-xorg-input-synapticsWe also download the dependencies so we can recompile it:
# apt-get -t unstable build-dep xserver-xorg-input-synapticsWe go to the directory where they were downloaded and apply the patch we downloaded earlier. (In our case version 1.4.0 was downloaded)
# cd /usr/src/xserver-xorg-input-synaptics-1.4.0
# cat /usr/src/99-clickpad.patch |patch -p1We recompile the package with the patch already included.
# dpkg-buildpackage -bWe install the package:
# sudo dpkg -i ../xserver-xorg-input-synaptics-*version*.deb(In my case: xserver-xorg-input-synaptics_1.4.0-1_amd64.deb)
Just the X-window is enough for us and the support improves considerably. Although there are still quite a few features that we will see implemented very soon by the kernel and Xorg developers.
And with this and a sponge cake, this developer can develop in peace.
