| + | |||
| + | This page will very often mention **local computers** or **remote computers**: | ||

| + | * The local computer can be a **Linux, Windows or Mac (i.e //OS X//) computer** | ||
| + | |||
| + | * The **remote computer or server** is another computer that you also want to interact with (using the screen+mouse+keyboard of your local computer) | ||
| + | * We only consider on this page the case of a **remote //Linux// machine** that **requires a local running //X server//** | ||
| + | |||
| + | * **Remote Linux machine** can mean several things: | ||

| + | * We mostly consider on this page the case of a **Linux virtual machine** using [[other:win10wsl|Windows Subsystem for Linux (WSL)]] on a Windows computer, but this can apply to other configurations | ||
| + | * It can be a **distant computer** or server in your building, or a high performance computer in a computing center on the other side of the Earth. It could also be a virtual machine in the //Cloud// | ||
