Hi Daniel,
To recover Xwin you'll have to dig around and look at start-up messages
to see what is fouled up (possibly lock-files etc), use ALT+CTRL+F1 to
get back to the X start-up window.
To avoid this in the future, your best bet is to get a 'crash machine'.
I use a cheap pentium 120 with a small linux system (50MB on a 100MB
partition). I NFS mount the application I'm trying to develop. If the
system crashes, the fsck of the crash machine is quick. This way I've
never lost anything on the NFS filesystem (although there's always a
first time :-)
Regards, Stuart.
