IBus incompatibility

[Guillaume Munch]

There is currently a serious incompatibility between LyX and IBus (the
default input method in Ubuntu and Fedora) that causes various problems:

 * The keyboard starts outputting the wrong keys

 * LyX completely and definitely stops responding

 * When using arrow keys or page up/down, the movement continues for a
long while after the key has been released.

If you have experienced these bugs and use Linux, then you may be a
victim of this incompatibility. The main trigger is a heavy system load
so it happen more often to users with long documents with which LyX is slow.

I have just found the reason to these bugs so I wanted to share the
workarounds:

 * Disable IBus just for LyX (if you don't need a special input method):
   Run LyX with the command line:
 XMODIFIERS= lyx
   or equivalently (in Ubuntu) adapt /usr/share/applications/lyx.desktop
   as follows:
 Exec=env XMODIFIERS= lyx %F

or:

 * Set IBus to synchronous system-wide (keeps IBus in LyX, but does not
   solve the third issue and causes problems with the hangul input
   method):
   Add the following line to .xsessionrc (create if needed):
 export IBUS_ENABLE_SYNC_MODE=1

Yes, my installation failed to update to El Capitan GM. 
I tried it with an external drive and it never completed
the final (?) step after rebooting the system.

So, I couldn't test LyX with it.

Thanks Scott. It is not the best solution, but I will set it up whenever
this error appears. Maybe this could be a flag that can be easily included
in new versions of Lyx.
