I have been following several tutorials to use VNC on my remote baremetal instance (chameleon cloud). I had to install a bunch of things since it did not have a GUI interface. I want to use this instance through the GUI.
Some details about my instance: I am running Ubuntu 22.04.4 LTS jammy x86_64. I use this instance through ssh. My xstartup file looks like this: #!/bin/sh
# Unset environment variables
unset SESSION_MANAGER
unset DBUS_SESSION_BUS_ADDRESS
# Start the D-Bus session
eval `dbus-launch --sh-syntax`
export DBUS_SESSION_BUS_ADDRESS
export DBUS_SESSION_BUS_PID
# Set the display environment variable
export DISPLAY=:1
# Start XFCE
startxfce4 &
I have been using this configuration since I found it on the internet. I will be happy to change it.
When I start my VNC server I get the following output:
New Xtigervnc server 'new-emu:1 (cc)' on port 5901 for display :1.
Use xtigervncviewer -SecurityTypes VncAuth -passwd /home/cc/.vnc/passwd :1 to connect to the VNC server.
=================== tail /home/cc/.vnc/new-emu:5901.log ===================
===========================================================================
Session startup via '/home/cc/.vnc/xstartup' cleanly exited too early (< 3 seconds)!
Maybe try something simple first, e.g.,
tigervncserver -xstartup /usr/bin/xterm
The X session cleanly exited!
Killing Xtigervnc process ID 6831... success!
And the respective log file:

Not sure what is going on. I just want to access my instance through VNC on my Mac so I can run some experiments using the GUI. Any help is welcome! Thank you!
