I solved this by preventing auto suspend. I did two things, one of
which solved this, although using both is probably heavy-handed, I'm
rather safe and logged in, with remote access to my machine than
sorry.
In the Enlightenment Configuration Panel, go to Screen, and un-check
any Power Management or Screen Saver options --- as in DO NOT use the
screensaver.
Then, edit (or ask your administrator to edit)
/etc/enlightenment/sysactions.conf. The file includes an explanation
of how to edit so as to allow and deny particular users the right to
suspend or reboot the computer. I just added
to this file, thereby denying myself the authority to reboot, suspend
or "hibernate" the computer.
I'm pretty sure the screensaver did it, because without editing the
.conf file, I have not had this problem at home. Either that or there
is some hardware based difference between the machines (my home
machine is much newer).
Thanks for weighing in,
Joel
