It is possible to use this driver with an ALPS Glidepoint device. If
|
|
you use an older 2.6 linux kernel which has no ALPS input driver, you
|
|
need to apply the ALPS kernel patch in the alps.patch file. See
|
|
http://www.kernelnewbies.org/faq/ for information about how to apply
|
|
kernel patches and compile kernels.
|
|
|
|
Note! If you use kernel 2.6.11 or later, the alps patch is already
|
|
included, so you don't have to patch your kernel.
|
|
|
|
Since ALPS touchpads don't have the same resolution as Synaptics
|
|
touchpads, you probably have to change some parameter values. Here is
|
|
an example InputDevice section for the X configuration file.

If you use a 2.4 linux kernel, you don't need to patch the kernel, but
|
|
you should instead set "Protocol" like this:
|
|
|
|
Option "Protocol" "alps"
|
|
|
|
|
|
On some (all?) ALPS hardware, it is not possible to disable tapping
|
|
unless you apply the patch below. However, some users have reported
|
|
that this patch breaks tap-and-drag operations, which is why the patch
|
|
is not included in the main alps.patch file.
