Hi Barry,

It sounds sort of like gnome-settings-daemon is not capturing the
settings properly, so your system is defaulting to 10 minutes.  I notice
this in your dmesg which hints perhaps gsd is dying (coincidentally in
some power module):

[22483.782153] gnome-settings-[2178] trap divide error ip:7fdd4a47931b
sp:7fff856edb10 error:0 in libpower.so[7fdd4a46b000+17000]

You can query and set the default X screen blanking via xset.  For
instance:

 $ xset q | grep -A4 DPMS
DPMS (Energy Star):
  Standby: 7200    Suspend: 7200    Off: 14400
  DPMS is Enabled
  Monitor is On

humber:~$ xset dpms 10 20 30
humber:~$ xset q | grep -A4 DPMS
DPMS (Energy Star):
  Standby: 10    Suspend: 20    Off: 30
  DPMS is Enabled
  Monitor is On

Run 'xset' by itself to see other options it supports.

Since the line in dmesg suggests something's gone wrong with g-s-d I'm
reassigning this bug there.  However, if you find tweaking dpms settings
via xset doesn't work around the bug, feel free to reopen an X task.
