FS#705 - Awesome freezes when switching from console -> back to X

----------
I may have found a necessary condition for the bug. My laptop has a touchpad
(AlpsPS/2 GlidePoint), and I use the synaptics driver for it, with hal/evdev
input hotplugging. I have a custom /etc/hal/fdi/policy/11-x11-synaptics.fdi
file, to customize some of the settings for that driver.
Formerly, one needed to use have the SHMConfig set to a boolean true value in
order to be able to dynamically change the driver settings from inside X. Some
GUI tools for configuring the driver also required this.
In my fdi file, that looks like:
<?xml version="1.0" encoding="ISO-8859-1"?>
<deviceinfo version="0.2">
<device>
<match key="info.capabilities" contains="input.touchpad">
<match key="info.product" contains="AlpsPS/2 ALPS">
<merge key="input.x11_driver" type="string">synaptics</merge>
</match>
...
<match key="input.x11_driver" contains="synaptics">
<merge key="input.x11_options.SHMConfig"
type="string">true</merge>
...
</match>
</match>
</device>
</deviceinfo>
I shut that off several hours ago, and started X, and since then the bug has
not appeared. Even starting gpm doesn't make it show up.
Now it turns out that this setting doesn't need to be on anymore: see
<http://fedoraproject.org/wiki/Features/InputDeviceProperties>. That's why I
turned it off. But even if that's true, it will take some time for users to learn
this, and for GUI tools that now require SHMConfig to be true to be rewritten to use
the new communication channel.
Until the use of SHMConfig has worked out of the userbase, this bug may bite
anyone who uses the synpatics touchpad driver, and who ever switches between
virtual consoles and X.
