Hi,
Have come across this problem :-s
What kind of applications were open ? Generally, I used to have an editor
session(emacs) running in a `konsole` to do the coding
and, an instance of firefox for browsing. Media player ran from inside emacs
or konsole.

Sandeep already has mentioned process checkpointing tools. The thing, i am
not sure about is - do they work for all cases, especially open
sockets(tcp/udp) and audio devices ? TCP sockets can be migrated using
connection passing, but i do not know whether it has been merged into the
kernel ?
The way i got around this problem was to use a terminal multiplexer. I
used `screen`. Not only does it keep your session safe when X crashes, it
offers an added advantage that, you can easily reattach to your existing
session(over a simple ssh/telnet connection) from any other machine(home?)
if you need to (say, while you are taking a conf call).
About Firefox, a session saving extension like tabs mix plus takes good
care of saving the session.
Another curious question about process checkpointing is - do cryopid etc let
the process continue to run after checkpointing ? or are they suspended when
checkpointed ?
My 2 cents...
Kindly CMIIW and, ignore if you already knew it :)
