I tried to display GUI on Mac with X Window System
■ Purpose
When managing a server, it is usually the CLI, but sometimes I want to use the GUI as well. At that time, I use VNC, but I also want to try X Window. So, let's try X Window the GUI display of Linix Compute of Oracle Cloud with MAC.
■ Configuration image
Try X from a Mac Book in an On-Premises environment with an Internet connection to OCI

■ X window execution from MAC to OCI Linux Compute
● Start XQuartz
- Start XQuartz terminal
Click the XQuartz icon in [Others] of Launchpad to start the terminal
Terminal startup will start
- ssh connection to OCI instance Ssh connections run with the -X option to enable the X11 forwarding feature
bash-3.2$ ssh -X -i id_rsa [email protected]
Last login: Mon Aug 10 12:50:03 2020 from 192.168.0.2
- Check the DISPLAY environment variable Confirm that the DISPLAY environment variable is automatically registered If it is not automatically registered, review the settings such as sshd.
[opc@oci-inst01 ~]$ env | grep DISP
DISPLAY=10.0.0.2:11.0
- run xclock Confirm that GUI can be displayed with xeyes command
[opc@oci-inst01 ~]$ xeyes
If xeyes cannot be executed and error: "Can't open display" etc. is displayed, check the environment such as Firewall to see if port 6000 is free.
