I warn everybody to edit their options to disable it.
Linux Mint 13. I had no cursor on my desktop. My down button hit Suspend
by mistake. It wouldn't turn on correctly for an hour. went back to
turn it on 40 minutes later and for once the screen appeared. I lucked
out. This works for Ubuntu, Linux Mint, Fedora thus far.
gksudo gedit /usr/share/polkit-1/actions/org.freedesktop.upower.policy
< allow_active>yes< /allow_active>
Disable suspend in Red Hat Enterprise Linux, Cent OS, Scientific Linux
gconftool-2 --config-source xml:readwrite:/etc/gconf/gconf.xml.mandatory
