You want to login to your Linux Mint computer using RDP (Remote Desktop Protocol) from another computer or phone.
First, we just set up the server, then we connect from the client.
To set up the Server:
ctrl+alt+t to open a terminal
echo env -u SESSION_MANAGER -u DBUS_SESSION_BUS_ADDRESS cinnamon-session>~/.xsession && sudo apt install xrdp freerdp2-x11 xorgxrdp && hostname -I
After the installs, you’ll see a readout with your IPv4 address. Make a quick note. (for example, 192.168.1.100)
To connect from another Linux Mint computer:
alt+f2, remmina and connect to your noted IP
To connect from a Windows computer:
winkey +r, mstsc and connect to your noted IP
To connect from a Mac:
Get Microsoft Remote Desktop from the mac store, open it, and connect to your noted IP
