[LAU] Screen blanking

[Ralf Mardorf]

Hi :)

how can screen blanking be disabled? A long time ago I have given up to
check this out for my Ubuntu Studio installs. FWIW it's not the monitor,
for an old Suse 11.2 install the screen never will be turned off.

Now I try to disable screen blanking on Arch Linux, Xfce 4.10.

$ uname -rm
3.8.13-rt14-1-rt x86_64

This doesn't work:

$ cat ~/.xinitrc
#!/bin/sh
#
# ~/.xinitrc
#
# Executed by startx (run your window manager from here)

if [ -d /etc/X11/xinit/xinitrc.d ]; then
  for f in /etc/X11/xinit/xinitrc.d/*; do
    [ -x "$f" ] && . "$f"
  done
  unset f
fi

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

exec startxfce4
# exec xterm

Power Manager is enabled when starting a session, but
Menu > Settings > Settings Manager > Power Manager > On AC >
All "Actions" and "Monitor" settings are set to "never".
