Comment 73 for bug 582809

bigbrovar, the psmouse tarball that I attached is the linux 2.6.35-22-generic source directory for the mouse (linux-2.6.35/drivers/input/mouse), with both of the synaptics.diff patches applied already. If you take a look at the synaptics.diff files, you can see they apply to the synaptics.c source file in that directory. The patch command is used to apply such patches (see man patch and man diff for more info).

The tarball also includes a dkms.conf file to make it work with dkms.

It does not include the /usr/share/X11/xorg.conf.d/50-synaptics.conf file changes to control the jumpy cursor. You have to do those yourself.
