Description: building xf86-input-evdev with mtdev support breaks 'Evdev Axis Inversion' and 'Evdev Axes Swap' and touch events. Please see upstream bug for details and progress.

Additional info:
Occurs in upgrade from xf86-input-evdev-2.7.2 to xf86-input-evdev-2.7.3 due to 2.7.3 being built with mtdev support

Steps to reproduce:
Install xf86-input-evdev-2.7.3
Modify input axes with: xinput set-prop <device id> 'Evdev Axis Inversion' 1 0
xinput set-prop <device id> 'Evdev Axes Swap' 1
Output of :xinput list-props <device id> shows changed input axes, yet input axes have not changed. All input remains as if the device properties were not modified.

Build xf86-input-evdev-2.7.3 without mtdev support.
This task depends upon

Reason for closing:  Upstream
Additional comments about closing:  this is either a bug in mtdev or in the closed egalax driver. you will be pretty much on your own for now. there's nothing we can do downstream. use abs to rebuild without mtdev support.

Hi. I have an ekoore perl tablet (wetab, exopc) with an egalax touchscreen. With 2.7.3 evdev driver I suffer all the issues that Padfoot comment in random focus, scroll not working with easystroke, evdev axis don't rotate touchscreen. Downgrading to 2.7.2 (from the snapshots in ARM) all these problems disappear. I believe, as Padfoot said, that building 2.7.3 driver without mtdev support is a solution

PD: I suffered the problems in Lubuntu 12.04 precise. I don't know if ubuntu's xserver-xorg-input-evdev was built with mtdev enabled or disabled.
