Most of the wacom plugin code protects X11 calls with gdk_error_trap_push/pop
and prints a warning if something fails. There were two calls that were not
protected, however, and one use of g_error instead of g_warning that would
cause the g-s-d process to die if e.g. the tablet disappears while g-s-d is
trying to work on it.
device-mapper: Reset the "display" setting on NULL outputs
We used to attempt to reconstruct the ['','',''] default, although
this failed on NULL outputs as we tried to feed NULLs into "as"
variants/settings.
Fix this by just resetting the key when the device gets a NULL
output, we can also make the other path clearer as we can't get
NULLs in edid[] as we previously might.
Based on a patch by Alexandre Rostovtsev <email address hidden>
Touchpad buttons are disabled also if touchpad is disabled using
"Device Enabled" property. Unfortunately some touchpads share those
buttons with trackpoint, which is consequently unusable. Disable
touchpad using "Synaptics Off" property instead to avoid disabling
the buttons.
Remove also some redundant calls to enable/disable touchpad and
make sure syndaemon isn't running if the touchpads are disabled.
