A couple of things you could try:
- Typically you have several virtual terminals, one of which has your
X display on it, one has hte console, and the rest have a text login
prompt. These are what you can get to with Alt-F1, Alt-F2 ... Alt-F7.
This is distro specific.
In the suspend script, try changing to a console VT before suspend,
then back to X on resume. The commands you need are 'chvt 1' and
(usually) 'chvt 7'. Do this in a ssh or telnet session before you edit
the script to make sure you're doing it right.
If that doesn't work, you might need to restart X on resume. Use something like
kill -HUP `pidof X`
If that doesn't work, kill X before you suspend, and then start it
again when you resume. How to do this depends on your setup. It might
be something like '/etc/init.d/gdm stop', or some other weird
Good luck. These problems can be a pain to fix.
