Carols, I see in the dmesg you supplied earlier ALPS was redetected
successfully, so I guess the problem is that your synclient quirk did
not run after resume. The best way to handle it would be adding a HAL
rule, something like this:
<?xml version="1.0" encoding="ISO-8859-1"?>
<deviceinfo version="0.2">
<device>
<match key="input.x11_driver" contains="synaptics">
<merge key="input.x11_options.SHMConfig" type="string">On</merge>
</match>
</device>
</deviceinfo>
You'd need to add add the corner tapping command.
Still, I am curious to know why we can't simply reinitialize ALPS from
the get go, could you please send me a dmesg of resume done with
i8042.debug? Thanks!
