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 ?Hi all,
Sorry for spamming the list because this is really not a kernel
question, but I am also not sure if this can be done in userspace
entirely. While working on my laptop today somehow I screwed my Xorg
settings and thus my whole X session. I had to reinitialize/restart X,
but that also meant I had to close all my important open windows :-(

I felt it would be nice if I could have stored all the current running
processes in some file (just like hibernate) and just restarted X with
that file (possibly as an argument). That would also mean I can save
different sessions :-) and then hibernate and then come back with
whatever session I wish.
Is anyone aware of any tool/project that tries to do this ??
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 :)
