Hey,

I need some help in resolving a major annoyance i have with mandriva. For whatever reason the screen goes blank when a key or mouse is not moved for some time. This is really annoying when watching a film or whatever, and i can't figure out how to turn it off as there is no option in the power management section. Anybody got any ideas??
Cheers

It sounds like it's your screen blanker kicking in. Some video players have a comand line option to disable the screen blanker. Otherwise, you can look in the powersaver section of your setup and disable it there.

If you are running kpowersave, then you can select the "presentation" profile. The blanker will be disabled in this mode.

Amazing!! I didn't have powersave installed, so i've installed it and set it to presentation. Cheers for the quick response, it was a really minor thing, but so annoying!!

Edit: Might have spoken too soon, the screen still goes blank, how do i stop this and make sure kpowersave overrights other options.
Cheers

A) Check in the MCC configuration for settings on screen blanking. I don't know whay kpowersave doesn't do it. Maybe you need to install the acpi support.

B) Check your bios. It may be doing it there as well. I think some older Dell laptops did that.

C) Some BIOSes didn't do a good job with the ACPI functions in the BIOS and a BIOS upgrade may fix the problem.

Hey,

From what i can understand on my notebook, acpi is a bit broken: [URL="http://gentoo-wiki.com/HARDWARE_Gentoo_on_HP_Compaq_nx6325"]
However, i've flashed the bios so its the most recent, but i don't know if acpi is working or not. How do i check this, and if it is broken how do i fix it??

Have you tried System > Prefererences > Screensaver then unchecking the 'Activate screensaver when idle' box (for Gnome)? If I remember rightly it can be done with a rightclick > Desktop Settings > on the desktop in KDE...

Running Mandriva 2007/KDE 3.5, During the install and configuration of 2007, turning off the screensavers cured my problem with the screen going black without any input for a short time, I normally don't use the screensavers so I don't know how it works when I turn it back on.

Problem Solved:

xset s off

I also added this to my ./xinitrc

setterm -blank 0 -powersave off -powerdown 0
xset s off

and in the monitor section of /etc/X11/xorg.conf

Option "DPMS"

Then in serverlayout of xorg

Option "BlankTime" "0"
Option "StandbyTime" "0"
Option "SuspendTime" "0"
Option "OffTime" "0"

Probably overkill but it seems to have sorted it as when i do
sleep 1; xset s activate

nothing happnes. Didn;t realise that there was an option to turn off screensavers in the post install config, but that would have helped. Cheers
