Xubuntu - Remotely lock/unlock your monitor using an Android phone
Today, I looked for a way to lock a Xubuntu machine remotely, and after a while of googling, I figured out this method: 1. I created 2 alias command to lock and unlock the monitor's screen (xscreensaver) in /home/myuser/.bash_aliases : alias lock='export DISPLAY=:0.0; xflock4;' alias unlock='export DISPLAY=:0.0; kill -9 "$(pidof xscreensaver)"; xscreensaver -no-splash &' 2. Install JuiceSSH (a ssh client) app in my Android phone: https://play.google.com/store/apps/details?id=com.sonelli.juicessh&hl=en 3. From my Android , connect to the Xubuntu machine via SSH with username ' myuser ', and then: To lock the screen, type this in my phone terminal: $ lock And unlock the screen with: $ unlock It's just fascinating! Feel like a hacker!!! \m/\m/\m/
