I ran into this problem just this weekend (using the 2.1.0 dev version of LyX
on a debian-based system). I happen to have figured out what I did wrong,
though it didn't have anything to do with forward/reverse searches; I thought
the condition was interesting: I put some ERT into my document to change some
enumeration settings (explicitly, the following command to change numbering to
a lowercase letter surrounded by parentheses:
\renewcommand{\theenumi}{(\alph{enumi})}). Later on, though, in playing with
that command, I changed it to the following:
\renewcommand{\theenumi}{(\theenumi)}. This, I think, is a sort of circular
definition, and pdflatex chokes on it, and LyX appears to be frozen (I think
it's waiting for pdflatex to finish its compilation).
If you haven't started LyX from the command line (so that you can simply
ctrl-c it), then you can use the following to kill the process:
From a command window, run "top" or "htop", and find the process (likely gs or
pdflatex) which is eating up resources and kill it that way.
OR
run the command "ps -ef | grep pdflatex" (or whatever process you suspect of
hanging), which will return the process number of the program running. Then you
can run "kill <process number>" (or, for extreme maliciousness, "kill -9
<process number>") to make LyX useable again.
Hope that helps!
