Automatic screenblank after 5 minutes

[Guest]

Hi everybody,

My screen goes automatically blank after 5 minutes, which annoys me. I looked for parameters to change, but to no avail. I then suspected acpi to be responsible for this. Looking in /etc/acpi/ I found the script screenblank.sh that blanks the screen when run. I renamed it, but no change (even after a reboot). That script loads the file /usr/share/acpi-support/screenblank. I renamed that file and since then, no blank screen anymore...

However, this is probably not the proper way to configure this bankscreen feature... Do you have a better solution?

Thanks in advance,
Pierre

Re: Automatic screenblank after 5 minutes

You can configure this behaviour in your system settings.
K Menu -> System Settings -> Monitor & Display -> Power Saving

The default is however 45mins on my system (fresh install)

From man xset:

xset - user preference utility for X

OPTIONS
-dpms The -dpms option disables DPMS (Energy Star) features.
+dpms The +dpms option enables DPMS (Energy Star) features.

dpms flags...
The dpms option allows the DPMS (Energy Star) parameters to be
set. The option can take up to three numerical values, or the
‘force’ flag followed by a DPMS state. The ‘force’ flags
forces the server to immediately switch to the DPMS state spec‐
ified. The DPMS state can be one of ‘standby’, ‘suspend’,
‘off’, or ‘on’. When numerical values are given, they set the
inactivity period (in units of seconds) before the three modes
are activated. The first value given is for the ‘standby’
mode, the second is for the ‘suspend’ mode, and the third is
for the ‘off’ mode. Setting these values implicitly enables
the DPMS features. A value of zero disables a particular mode.

You could check if you have in the /etc/X11/xorg.conf option "DPMS".

Section "Monitor"
Identifier "VX2235wm"
Option "DPMS" <-------- this enables dpms
HorizSync 30-130

Re: Automatic screenblank after 5 minutes

Hi,

Sorry for this late reply. Busy and no access during the week...

The configuration in the Motinor & Display did not change anything... and the renaming of the file /usr/share/acpi-support/screenblank either actually (I was wrong when I said I had no bank screen anymore).

I modified the xorg.conf file to comment the option dpms. It seems to work, but I will confirm it...

Thanks for your help!
Pierre

01.06.07: Hi again. I was right to wait before to confirm. the dpms option does not solve the issue. I am going to contact the manufacturer (Keynux) and I will let you know if we find the solution.
