[Bug 123775] Re: Elantech touchpad is incorrectly recogonised as a "ImPS/2 Logitech Wheel Mouse"

[linuxonbute]

GSynaptics is used to configure 'synaptics' touchpads
( there are also qsynaptics and ksynaptics which do a similar job).
To use any of these you need a line in xorg.conf which is :
option "SHMConfig"  "true"

But when I try to run it I get the message:

GSynaptics couldn't initiaize.
You have to set 'SHMConfig' 'true' in xorg.conf or XF86Config
to use GSynaptics.

As far as I have been able to find out this is to do with shared memory

and I have read that this is disabled as it is considered a security risk in
Ubuntu.

So I guess this means it is not a bug in the driver. I also believe that it
may be possible to set values manually in xorg.conf

At the moment I have tapping disabled with
option 'MaxTapTime' '0'
in xorg.conf

Before using your patched kernel this was ignored and touchpad was
unusable.

However, at the moment I do not know what parameters are available
when using the elantech touchpad.
If it helps I will try to find out more options and see what works.

Please note that even if nothing more can be done I would much prefer
what is available with this patch than anything else I have tried.
Thanks,
Norman
