Adjusting monitor-power-off-time doesn't work -- again

[froebi]

Hi there,

with a fresh Feisty installation I tried to adjust my monitor's power-off time. I tried it using the "System Settings"->"Monitor & Display"->"Power saving"-tab. The default was a power-off time of 45 minutes.

So I switched to Administrator mode and adjusted the power-off time. Fine, I thought. After loggin out, restarting the X-server and loggin in again I had to realize that my changes were simply ignored. The power off-time was still set to 45 minutes. Damn!

So what is this all about? The thing is that this wasn't working in Dapper and Edgy neither.

If it still doesn't work, why don't you just drop or disable this "feature"? Maybe leaving a note how to adjust the power-off time by hand in /etc/X11/xorg.conf.

In fact, the first time I tried to adjust the power-off time, it completely corrupted my X-server configuration, leaving me with a nice 640x480-resolution after restart. Luckily I had a backup of my xorg.conf.

So I can only advise everybody to refrain from using the "Monitor & Display"-interface.

regards,
Christian

Maybe this ...

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.

In the konsole:

:~$ xset -q

tells:

DPMS (Energy Star):
clip....
Standby: 1200 Suspend: 1800 Off: 2400
DPMS is Enabled
Monitor is On
clip....

Changing:

sudo xset dpms 2000 2500 3000

Check:

xset -q

DPMS (Energy Star):
Standby: 2000 Suspend: 2500 Off: 3000
DPMS is Enabled
Monitor is On

If it still doesn't work, why don't you just drop or disable this "feature"? Maybe leaving a note how to adjust the power-off time by hand in /etc/X11/xorg.conf.

Hmm - maybe in the next version

K> System Settings > Monitor & Display reads and writes xorg.conf. It does this poorly. It also backups xorg.conf -> xorg.conf.1 (xorg.conf.2...) but doesn't tell this >

Hmm - minimum should be warning :
