Take the 2-minute tour ×  The display on these PowerEdge systems
goes to sleep after some period of time. Normally, when you plug
in a KVM, you have to press a key to "wake up" the display. I'm
connecting these servers to a KVM switch, and I'd like the
display to NOT go to sleep -- so when you select a system via
the KVM switch you immediately see the console display. OS on
these boxes is Linux, Ubuntu Lucid (10.04).  share|improve this

accepted  With X11 you want to disable DPMS in
/etc/X11/xorg.conf.  #In the "Monitor" section, you need a line
like:         Option          "DPMS" #Then, in the
"ServerLayout" section (for Xorg 7.2 and later, make a #separate
ServerFlags section instead), include lines like this:
Option          "BlankTime"     "0"         Option
"StandbyTime"   "0"         Option
