Integrating your Linux Desktop Ubuntu with your Android Smartphone

It is possible to integrated and control your Linux desktop with your smartphone, similar as it work for Apple iPhone and MacBook.

All you need is to install GSConnect on your computer:

https://extensions.gnome.org/extension/1319/gsconnect/

And install (ironically) KDE Connect on your smartphone.

Command to list the time you turned you computer on

This is a simple and nice way to know the exact time your computer was turned on:

$ journalctl --list-boots


It only works if your systems are running systemd-journald and you have the directory /var/log/journal
