I am running Mint 13 connected to a Dell U2711 monitor via displayport.
When the GDM logon screen is displayed, DPMS does not ever shut down the monitor.
If I logon and run
$ xset -q
... Screen Saver: prefer blanking: yes allow exposures: yes timeout: 0 cycle: 0 ... DPMS (Energy Star): Standby: 600 Suspend: 600 Off: 600 DPMS is Enabled Monitor is On
If I run
$ xset dpms force off
The monitor blanks for about two seconds, and then it comes back on again.
I have tried disabling my mouse as this post suggests with
$ xinput --set-prop [id] "Device Enabled" "0"
but no luck.
The symptoms are a little different than this post's, and I am not running gnome-power-manager.
Could someone please tell me what I am doing wrong?
Here is my video card and driver information:
