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. ** Package changed: xorg (Ubuntu) => gnome-settings-daemon (Ubuntu) ** Changed in: gnome-settings-daemon (Ubuntu) Importance: Undecided => Medium -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/836945 Title: Screen always goes blank after 10 minutes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-settings-daemon/+bug/836945/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
