===== Dependencies =====
You'll need a local X11 server. Options include

  * For macOS, [[https://www.xquartz.org/|Xquartz]]
  * For Win,  [[https://mobaxterm.mobatek.net/|MobaXterm]] (for UPMC managed computers, see local [[:tools:mobaxterm]] notes) or [[https://sourceforge.net/projects/xming/|Xming]]
  * Prerequisites (Xwayland or Xorg) are likely already available when already on Linux or [[https://learn.microsoft.com/en-us/windows/wsl/install|Windows Subsystem for Linux]]. 

===== Setup =====

Use ''-Y'' or ''-X'' with your ssh connection command to enable display forwarding.
<code>
ssh -Y $USERNAME@$REMOTEHOST
</code>

You can make this the default in ''~/.ssh/config'' using ''ForwardX11'' and ''ForwardX11Trusted'' directives. Note: ''Host *'' is for all hosts. You might want to replace ''*'' with a single or list of specific ssh servers. 
<code>
Host *
   # we don't need to encrypt X11 (faster)
   ForwardX11 yes
   ForwardX11Trusted yes
</code>
