Turn or switch off your monitor display using command line in Ubuntu Linux

This is how you can manually turn or switch off your display or monitor using command line in Ubuntu. You can set a keyboard shortcut to run this so that you can manually turn off your display.


To switch off the display:
xset dpms force off
To switch on back the display (in case you are doing this from remote login):
xset dpms force on
To check the status of the display (also in case you are doing this from remote login):
xset -q
Note: Once the display is switched off, any keypress or mouse movement will switch on the display.

In case you are going to assign the switching off display command to a keyboard shortcut, please use this command instead:
gnome-screensaver-command -a && xset dpms force off
This is because there seems to be an issue to run the xset command from the shortcut. The monitor switched off for momentarily and then it switches on back.

Mounting NFS share directory from D-link DNS 320L on Ubuntu 12.04 LTS

Image
Seems like the steps on how to get the NFS mount point from the D-Link DNS 320L NAS server were not properly documented in their user manual. After setting up and enabled the NFS service on the D-Link DNS 320L NAS server, I went ahead to setup and mount the share directory/folder in Ubuntu 12.04 LTS assuming the mount point in NAS was /Volume_1/... but that is not the correct mount point to start with! Found this answer from D-Link forum post from a member (ba43123) that helped me to correctly mount the NFS share directory/folder on Ubuntu 12.04 LTS: After spending most of the last hour on the phone with D-Link Technical Support, I came away with the recommendation to take my Mac (which has successfully connected to a number of NFS shares in the past) to Apple to determine if the network settings for NFS are correct.  This is mostly due to the fact that the people who are taking the calls have no information about NFS in their scripts and Knowledge Base so they are at a total loss in
