Default Dell Latitude E6410 (NVIDIA NVS 3100M) fails to restore screen after DPMS suspend

To trigger this I do:
- Suspend screen by running:
$ xset dpms force suspend
This turns off the display and backlight as expected.

- Touch a key or move mouse
Backlight comes back on but display remains black.
In /var/log/Xorg.0.log I see:
(WW) NVIDIA(GPU-0): LGD (DFP-3): Failed to set DisplayPort power state
(WW) NVIDIA(GPU-0): LGD (DFP-3): Failed to set DisplayPort power state
(EE) NVIDIA(GPU-0): LGD (DFP-3): DisplayPort link training failed

Changing VTs (ctr-alt-f1 + ctr-alt-f7) restores the display.

Also I noticed that running:
$ xset dpms force on
Makes the screen flicker off and inmediately back on. In /etc/Xorg.0.log I see:
(WW) NVIDIA(GPU-0): LGD (DFP-3): Failed to set DisplayPort power state
