Hi -

Eric Weiss mentioned in a mail that current ts test patches cause udev
and X to choke.

I'm guessing its because I changed the PRESSURE input event thing to be
from 0 - 1 to 0 - 100.  Udev needs a new rule, Eric said (thanks Eric):

| i had to add :
| SUBSYSTEM=="input", KERNEL=="event[0-9]*",
| SYSFS{modalias}=="input:b0013vDEADpB
| EEFe0101-e0,1,3,k14A,ra0,1,mlsfw", SYMLINK+="input/touchscreen0"
|
| to my udev/rules.d/lcaol.rules

X complains about the touchscreen being "extended input device".

Assuming we get the pressure stuff working properly after the current
crisis, what's the plan about supporting that in X then, assuming that's
what it is?

- -Andy
