cannot (un)set powersave mode

I recently rebooted my machine, and usually when I am under an x-windows session, I have it set not to use any kind of power save feature for my monitor. I do not have the DPMS option in xorg.conf, and I made sure that rc.acpid would not load (chmod -x) and commented out the setterm option in rc.M. So after about 15 minutes, my screen goes blank still, so I also made sure that xset s off was in my .xinitrc, so now thats taken care of, and still my screen goes blank.

I then decide to try this command while in my x-windows session:

Code:

setterm -blank 0

After a while, still it goes blank, so I decide to exit to a CLI, and do the following as root:

Code:

root@slackuser:/home/slackuser# setterm -blank 0 -powesave off -append

Ok, so the command works, so I go back into x-windows, and yet it goes blank again, so I try the same command as root (su), in xterm, but then I get a different result:

Code:

root@slacker:/home/slackuser# setterm -blank 0 -powersave off -append

cannot (un)set powersave mode

root@slacker:/home/slackuser#

Now what!? I made sure acpi/apm were not loading, why is it still going blank, and what should I try next? :scratch:

I was getting annoyed with that problem as well until I solved it recently (I don't remember where I found the solution, but it required much googling). I don't know if this will solve your problem, but I added the following to my /etc/X11/xorg.conf file, immediately after the

Code:

Section "Module"

...

...

EndSection

and before the

Code:

Section "InputDevice"

Here it is:

Code:

Section "ServerFlags"

    Option        "blank time" "0"

    Option        "standby time" "0"

    Option        "suspend time" "0"

    Option        "off time" "0"

EndSection

Hope that helps (if not, sorry...)

That worked exactly the way I needed, thanks!

Glad I could help! Now you can adjust everything via KDE's power management settings (if you use KDE) if you want and it will actually work.

Apparently the root of the problem is /etc/rc.d/rc.M, as explained in this (new) post:
http://www.linuxquestions.org/questi...d.php?t=582748

Basically, undo my solution and use the new one -- this avoids overriding a setting and instead undoes the root of the problem. Sorry for the bad advice!

[edit]I just reread your first post and saw that you already commented out the line in rc.M. Never-mind then...:)[/edit]

Thanks from a Eee PC 701 Xandros user

Thanks T3Slider. I just want to post it here so people googling the same problem can find a solution to a crazy set up in the Eee PC.

Suppose you want to set an Eee PC to display a little presentation with its characteristics, price and goodies. Well guess what, every 20 mins. it will blank the screen. This is the only solution to the problem I have found that works.

Again

Linux Eee PC 701 Xandros and Blank Screen Off, the rest of the key words can be found easily in your posts. Thanks a lot.
