My only problem now is with the video signal powering down after 10
mins. I can't find the configuration setting anywhere and searching
the internet has so far only turned up people in the same situation -
it's not the BIOS, it's not X (it happens on the command line too),
and I can't see any settings in /etc that might regulate it.
Check /etc/X11/xorg.conf file (look for "OffTime" in xorg.conf(5).
Check /etc/console-tools/config file:
BLANK_TIME=0
BLANK_DPMS=off
POWERDOWN_TIME=0
I suggest setting them that way and see if it makes a difference, then
adjusting later if necessary.
In X, what is the output of:
$ xset q | grep -i dpms
according to the man page, the default for OffTime is 40 mins, but my
signal
power-down happens after 10 mins.
The xset output is:
DPMS (Energy Star):
Standby: 1200 Suspend: 1800 Off: 2400
DPMS is Enabled
Monitor is On
interesting. In /etc/console-tools/config I have:
BLANK_TIME=30
POWER_DOWN=30
Partial success! The screen no longer blanks in command line interface.
However it still blanks in X. First, using Option "DPMS" "Off" in xorg.conf
"Monitor" section has no effect. xset shows DPMS is on.
My new "ServerFlags" section also has only limited effect. (see xset output
below)
Section "ServerFlags"
Option "BlankTime" "0"
Option "StandbyTime" "0"
Option "SuspendTime" "0"
Option "OffTime" "0"
EndSection
I have checked that this is the only xorg.conf being read. The output from "xset
q" for the screen saver (disabled in the xfce config menu) is what I think still
needs to change:
Screen Saver:
prefer blanking: yes allow exposures: yes
timeout: 0 cycle: 600
DPMS (Energy Star):
Standby: 0 Suspend: 0 Off: 0
DPMS is Enabled
Monitor is On
