HOWTO - Toggle Monitor Off/On at X startup

**shotgunefx** · 05-28-2006, 08:34 AM

I have a problem with my Lilliput. When X starts up, my monitor goes nuts. Toggling the power button fixes it.

Being lazy, I came up with the following fix.

Make sure power management is set up for your monitor in xorg.conf

Code:

Section "Monitor"
  Option "DPMS"

Make a script called togglemonitor (probably should put it in /usr/local/bin)

Code:

#!/bin/sh
/usr/X11R6/bin/xset dpms force off
/usr/X11R6/bin/xset dpms force on

Then in your Xsetup file (under something like /etc/kde3/kdm/Xsetup for KDM, I believe for xdm and gdm there is an equivalent)

Add the following line

Code:

/usr/local/bin/togglemonitor

Anyone else have this problem btw?

One of the Dell 2001FP monitors on my desktop at work goes nuts occasionally when (re)starting X with green vertical lines until I turn it off and on again. A minor annoyance on a desktop but it would be an extreme annoyance in the car. If I run into that problem I'll be sure to try your fix (although I'm currently eyeing a Xenarc screen for the install in my van).

Yes, it's very annoying.

It seems like with the new install, everything is (at least configuration wise)

I knocked this out in a couple minutes, which wrongly gave me the impression that everything would go smoothly. Seems the more mundane the task, the more problematic it's being. Enough venting..
