According to: https://help.gnome.org/users/gnome-help/stable/screen-shot-record.html.en
We can record our screens using Ctrl+Alt+Shift+R, works very well. But I have 2 screens or monitors. When recording, the software captures both screens, but I only need to capture one.
How can I record only one screen?
(not duplicated because i'm specifying version of Ubuntu, other questions are about ubuntu without version)
Does ubuntu 18.04LTS require antivirus/malware?
wich is the best option? if yes.
i have Nod32 but i'm not sure if this is the best option, useful or at least required.
Lastest Nod32 (Linux) version is 4, looks like Nod32 does not care Linux.
is there a good, professional option?
