<div style="font-family:verdana,sans-serif">If you disable DPMS in
your Desktop environment, and disable xscreensaver and find
that DPMS and/or screensaver is still kicking in, you can try
running "xset q" to query things. For example, my system
sometimes shows this:</div>

<div style="font-family:verdana,sans-serif">The "s off" option
turns off the screensaver (timeout: 1800 to timeout: 0) and
the "-dpms" option disables DPMS. On some of my systems, I put
that command in my user's $HOME/.xprofile and it essentially
disables them at login. I have done this with Xfce as well as
LXDE.</div>

</blockquote><p>Great tips. The xset q showed that screensaver was off;
'standby' and 'off' where 0 (never), but DPMS was enabled. So I
set it off with the settings app. So xset q now shows DPMS
disabled.<br>
</p><p>It seems to be working at this point, but I need to switch from
the PC to another device for an hour or so and see if it comes
back correctly. I've left the PC at the Mythtv top menu.</p><p>Thanks,<br>

If my system is not running mythfrontend then I can leave the power management in Presentation mode which turns off DPMS.

I have to do Ctl-Alt-F1 and login to CLI and reboot.</div><div><br></div><div>What I have found works in all cases is Screensaver installed and disabled, and DPMS enabled with all the timers set to Never.</div><div><br></div><div>Jim A<br><br></div></div></div>
