purple terminal

For reasons that I do not understand, most distributions including Linux Mint and my old favourite Ubuntu, doesnt seem to turn the display off once I have locked it (with keys Ctrl+Alt+L). For me, when I lock the display, it means that I am not interested in seeing anything on the display; or I am going away from the display/computer (physically). Either way, my intention was to make it secure while I leave it unattended! If I am not interested in the display, wouldn't it make sense to turn it off as well?! For me logically yes! Anyway, I had to make it work like that for me. Had to knock-together a little script and re-assign the lock keyboard shortcut to execute that script.

For our purpose, we need to setup an event monitor and make the event do something; which is in our case monitor for write+close event, and ask gnome (in my case) to open the file. The best we can do is to run a background script on gnome session startup . The script as below; make sure you set execute permission on the file. #!/bin/bash if [ "$1" != "-nohup-" ]; then     nohup $0 "-nohup-" </dev/null &>/dev/null &     exit 0; fi inotifyw...
