Screen on VGA port going to sleep

Hi,

I use an old laptop as a media station, router, and web server. Its screen is broken, so I use a projector attached to the VGA port. The projector sits on the closed lid.

To properly watch movies I have set XFCE's power management to never turn off the screen, however, every 10 minutes the projector loses the signal, and it can only pick it back up if I connect (I use VNC) and move the pointer.

How do I make this work? I know it's not a hardware issue because it worked fine when I used Xubuntu.

Thank you

Re: Screen on VGA port going to sleep

There are two things you need to set - dpms (display power management system), and the screensaver. XFCE probably has separate configuration modules for them, but you might have set only one of them. So check XFCE's screensaver settings.

If that won't work, go low-level - install xorg-xset and do

xset -dpms
xset s off

To check status, there's "xset q"
