having successfully built my new gentoo installation, I have encountered my first problem

if there's no interaction with the pc on my behalf after a while the screen turns off.

the problem is I can't wake it up again, and when I try - it freezes.

I have to reset the pc

so this means I can't install any software cause during the install the screen will turn off, and then ofcourse I get my crash.

I have a feeling it's to do with power saving, apm or acpi but not sure what exactly.

it may be as simple as recompiling my kernel and omitting something this time round.

any ideas what? take off apm ? any thoughts greatly appreciated!!

you can stop console blanking by:

Code:

setterm -blank 0


i dont know if this command works
:idea: if it doesn't you sould consult the manual of setterm :idea:

Does anyone know where gentoo manages the blanking of the screen after 15 mins? I remember from the past that there is a line that says 'blankscreen 15' or something similar but I dont know in what script that was...

Any ideas?

If it's the same in Gentoo as it is in Debian, then do:

Code:
setterm -powersave off

This is more of a noob question :)

How the heck do I disable the power saving features. It keeps blacking out my monitor and I have to wiggle the mouse every time it does that to turn the monitor back on.

setterm -blank 0

it's not really a newbie question, it's one of those "wow, I've never really bothered to WORRY about this before, but how the hell DO I do it?" things :)

Does this have to be done every time or added to some config file to work every time the machine reboots?

Thanks agian :)

yeah, you'll have to do something with it.

What I'd do is make a file called "noscreenblank" in the /etc/init.d and put setterm -blank 0 in it.

Then, rc-update add noscreenblank default

if you ever wanna stop it from doing that, you can just rc-update del noscreenblank default

Okay, it's an X screensaver then, probably.

Are you running KDE?

Nope, XFce
I found out where to change the options...Now I have to figure out which one :)

I have to edit the XF86Config file and add something along the lines of "noblank" or something like that

I'll read the X man pages a bit more in a bit

thanks arkana, this really helped me out (kind of annoying if your monitor blanks out every 10 minutes while watching mplayer on console ;-) )

use xset, don't remember syntax off top of my head, think it is this:

xset -s 0
xset -dmps

you can do man on xset and get the correct syntax.

ok, so I have no power management built into my kernel, so how do I stop my monitor from being shut off after 10 minutes??? It's really annoying having to shake my mouse every few minutes while watching movies.

thats probably some setting in kcontrol.
or whatever windowmanager you are using. and maybe you have it set to suspend after 10minutes in bios.

Well, John and I have the same problem in X and in console, its not in either of our bioses OR compiled into kern.

The only thing i found was adding this subsection into XF86config

Section "ServerFlags"
Option "SuspendTime" "0"
Option "StandbyTime" "0"
Option "BlankTime" "0"
Option "OffTime" "0"
EndSection

hi

to avoid blank screen
just type xset in your console for more options
don`t know the correct one (sitting on w2k-box) , maybe 'dpms off' or '-dpms 'or 's dpms'
one of these worked for me (also the dpms options in XF86config)

Hello,

This is a common question (at least on IRC) and I have yet to find a working explanation.

I wish to set my computer so that:

a) The monitor does not go on suspend in the console.

b) The monitor does not go on suspend in XFree.

People have quoted xset lines, yet none have worked for me (unable to open display such and such).

I had (at one point) a working command to disable it in the console, yet I lost the functionality in a reboot, and I can't rememeber the command.

Thanks!

For the console, I don't know.
For X do this:
Code:
xset s off

if that doesn't work, then there is something wrong. I use that all the time to stop my X from blanking out when I'm watching Tv on it ;)
