The -s 0 option is keeping them on.... I guess there was some kind of default screen-saver. <div class="gmail_quote">On Sat, Jan 16, 2010 at 1:26 PM, Hal Glenn <<a href="mailto:hglenn@2g-eng.com">hglenn@2g-eng.com</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">This is just a general question that maybe related to the libdlo stuff. I've got 10 Mimo 720 monitors running on 10 X servers. Each X server seems to be blanking the screen after about 10 minuets of no touch input. The screen comes right back after I touch it. I know this is probably not related to the Display Link community but I figured I'd ask... I've tried disabling -dpms in the X start-up command line and I have these options set in my X conifg Option "BlankTime" "1" Option "StandbyTime" "1" Option "SuspendTime" "1" Option "OffTime" "1" So one would think they would blank after about a minute... can anyone think of a reason this might be related to the libdlo or point me in another direction?
