How to Run TightVNC in 1080p on Ubuntu 24.04 Google Cloud VM If you're running an Ubuntu 24.04 virtual machine on Google Cloud and need remote desktop access, TightVNC is a lightweight and efficient solution. However, by default, VNC sessions start at low resolutions, which can make remote work frustrating.

This guide shows you how to install TightVNC and run it in Full HD (1920x1080 resolution) on a Google Cloud VM.

Why Use TightVNC? Lightweight and fast for cloud environments

Works well over SSH tunnels

Compatible with multiple VNC clients

No graphical display attached needed (perfect for headless servers)

Step 1: Set Up Your Google Cloud VM Make sure your Google Cloud VM:

Runs Ubuntu 24.04

Has the firewall rule open for TCP port 5901 (or use SSH tunneling for security)

Step 2: Install TightVNC and XFCE4 Update your system:

bash Copy Edit sudo apt update sudo apt install tightvncserver xfce4 xfce4-goodies dbus-x11 -y Step 3: Start VNC for the First Time Run:

bash Copy Edit vncserver :1 You'll be asked to set a VNC password. This starts the VNC server with a default low resolution, but you’ll fix that in the next step.

Step 4: Configure 1080p Resolution Kill the default VNC session:

bash Copy Edit vncserver -kill :1 Now restart VNC with Full HD resolution:

bash Copy Edit vncserver :1 -geometry 1920x1080 -depth 24 Step 5: Set Up XFCE4 for TightVNC Edit the xstartup file:

bash Copy Edit nano ~/.vnc/xstartup Replace its contents with:

bash Copy Edit #!/bin/bash unset SESSION_MANAGER unset DBUS_SESSION_BUS_ADDRESS

export XDG_SESSION_TYPE=x11 export XDG_CURRENT_DESKTOP=XFCE export DESKTOP_SESSION=xfce

xrdb $HOME/.Xresources || true

if [ -z "$DBUS_SESSION_BUS_ADDRESS" ]; then eval $(dbus-launch --sh-syntax --exit-with-session) fi

startxfce4 & Make it executable:

bash Copy Edit chmod +x ~/.vnc/xstartup Step 6: Connect to Your Server Use your favorite VNC viewer (RealVNC, TigerVNC, TightVNC client, etc.) Connect to:

makefile Copy Edit your-server-ip:5901 If you're concerned about security, consider SSH tunneling instead of exposing port 5901 to the internet:

bash Copy Edit ssh -L 5901:localhost:5901 youruser@yourserverip Then connect your VNC viewer to localhost:5901.

Optional: Prevent Display Errors If XFCE complains about "Unable to change RandR display settings," you can disable display auto-detection by creating this file:

bash Copy Edit mkdir -p ~/.config/xfce4/xfconf/xfce-perchannel-xml nano ~/.config/xfce4/xfconf/xfce-perchannel-xml/displays.xml Paste:

xml Copy Edit

Summary Command Purpose vncserver :1 -geometry 1920x1080 -depth 24 Start VNC in 1080p chmod +x ~/.vnc/xstartup Ensure VNC can run XFCE4 SSH Tunnel Secure remote access

Final Thoughts Running TightVNC in Full HD on Google Cloud Ubuntu 24.04 is a simple way to get a remote desktop without the overhead of heavier solutions like Remote Desktop Protocol (RDP).

This setup works great for:

Managing servers visually

Running lightweight GUI apps

Teaching and demonstrations in the cloud
