Hey Answerguy,
|
|
</STRONG></P>
|
|
<P><STRONG>
|
|
I'm working on an information kiosk system, running Redhat
|
|
6.1. This thing is touch screen driven and in it's production
|
|
envirnment is not going to have a keyboard or mouse attached. It
|
|
plays mpeg video files, interspersed with gif "menu" screens. For
|
|
performance reasons (the machine is only a 233 MMX) I want to run
|
|
this under a very bare fvwm2 (no title bars etc.) but fvwm2 seems
|
|
to automatically blank the screen after about 5 minutes of no
|
|
activity. This does <EM>not</EM> happen under <A HREF="http://www.kde.org/">KDE</A>. A few facts:
|
|
</STRONG></P>
|
|
<P><STRONG><ol>
|
|
<li> I compiled the kernel <EM>without</EM> apm support.
|
|
<li> apmd is not started in any run level I am using (4 for the
|
|
actual kiosk mode, 5 for testing)
|
|
<li> Power management is disabled in both the bios and the monitor.
|
|
</ol></STRONG></P>
|
|
<P><STRONG>
|
|
I've been poking around in documentation all day trying to find
|
|
out if there is a way to keep fvwm2 from blanking the screen, to
|
|
no avail. Any hints, clues, or just plain answers will be greatly
|
|
appreciated.
|
|
</STRONG></P>
|
|
<P><STRONG>
|
|
Thanks,
|

Jay

I don't think fvwm2 is actually the problem here. Try
|
|
adding the following to your <tt>.Xclients</tt> or <tt>.Xsession</tt> script:
|
|
</BLOCKQUOTE>
|
|
<BLOCKQUOTE><BLOCKQuote>
|
|
xset s off
|
|
</BLOCKQuote></BLOCKQUOTE>
|
|
<BLOCKQUOTE>
|
|
... The <tt>xset</tt> command can control various settings in your X
|
|
server. In this case I'm just disabling the X "screen blanking"
|
|
feature. Read the '<tt>xset</tt>' man page for details.
|
|
</BLOCKQUOTE>
|
|
<BLOCKQUOTE>
|
|
To prevent text console blanking you can use the '<tt>setterm</tt>'
|
|
command like so:
|
|
</BLOCKQUOTE>
|
|
<BLOCKQUOTE><BLOCKQUOTE><CODE>
|
|
setterm -blank 0
|
|
</CODE></BLOCKQUOTE></BLOCKQUOTE>
|
|
<BLOCKQUOTE>
|
|
... note: the Linux text console blanking feature is normally
|
|
NOT active when X is active. So you shouldn't HAVE to take both
|
|
these steps in your case. However, it won't hurt. Meanwhile I
|
|
mention the <tt>setterm</tt> command for the benefit of my other readers.
