Unable to use Remote Desktop Connection to VM instance using Oracle Linux 8.6 and XRDP

edited Jul 28, 2022 7:24PM in OCI - General 2 comments

I created a VM instance on Oracle Cloud, using Oracle Linux 8.6. I added TCP 3389 port in VCN on OCI before installing GUI.

I want to install GUI and allow RDP connection to VM instance, so I installed GNome GUI and XRDP with the following commands (# is I use root user):

# dnf groupinstall "Server with GUI" -y
# systemctl set-default graphical
# reboot

Then uncomment the following line in the /etc/gdm/custom.conf file to ensure that VNC uses X.org instead of Wayland:

WaylandEnable=False

After that, I installed TigerVNC Server and XRDP:

# yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm -y
# yum install tigervnc-server xrdp -y
# systemctl start xrdp
# systemctl enable xrdp
# firewall-cmd --permanent --add-port=3389/tcp
# firewall-cmd --reload
