screen does not go blank after the configured period

[Tomislav]

Configured the screen to go blank after 10 minutes and then locked the screen.

Expected it to go blank, found it turned on later.

[Daniel van Vugt (vanvugt)]

Thanks for the bug report.

Your kernel log is saying that the Nvidia driver is not cleanly installed, so please use the 'Additional Drivers' app to remove it, then reboot, then reinstall it using the same app.

Please also consider installing a newer Ubuntu release. The one you have will reach end of standard support next year.
