What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
You can run a graphical Linux desktop on a headless VPS and reach it through Chrome Remote Desktop without opening a public RDP port. The reliable path is to install Google’s Debian package on a 64-bit Debian-based server, add a lightweight X11 desktop (usually Xfce), authorize the host from Chrome Remote Desktop’s SSH setup page, and create a six-digit PIN. Connections are encrypted and normally use outbound service traffic rather than a listener on TCP 3389.
Need a server to try this on? Antihost offers Linux VPS plans with NVMe storage, full root access and a 14-day free trial.
This guide covers Debian and Ubuntu VPSs, including the Xfce session configuration that prevents common blank-screen failures, the exact authorization flow, firewall requirements, LAN/VPN-only policy, and systemd troubleshooting commands.

What you are setting up
A VPS normally has no monitor, keyboard, or desktop session. Chrome Remote Desktop adds a host service and starts an X11 desktop session when you connect from the browser. The remote computer then appears in the Chrome Remote Desktop Remote Access page, and the Linux desktop is rendered inside your local browser window.
This is different from installing a conventional RDP server. You do not need to expose TCP 3389 to the internet for Chrome Remote Desktop. Google’s troubleshooting guidance calls for internet access, outbound UDP with inbound responses, TCP 443 (HTTPS), and TCP/UDP 3478 (STUN). The service establishes an encrypted remote session; Google states, “For your security, all remote desktop sessions are fully encrypted.”

Prerequisites and compatibility
- Operating system: a 64-bit Debian-based Linux distribution. Google’s Compute Engine example uses a Debian boot disk; Canonical’s instructions target Ubuntu 22.04 LTS.
- Access: an account with
sudorights and SSH access to the VPS. - Desktop: an X11 desktop environment and window manager. A server image with no graphical packages is not sufficient.
- Browser: a local computer capable of opening the Chrome Remote Desktop setup and Remote Access pages.
- Network: outbound connectivity for the host and firewall rules that permit the documented HTTPS, UDP, and STUN traffic.
- Graphics: do not depend on 3D acceleration. Chrome Remote Desktop does not support 3D graphics acceleration for Linux hosts; disable 3D features in the selected desktop.
Package names and supported releases can change. Before deploying a new server image, verify the current package instructions on the vendor’s page rather than assuming that an old Debian or Ubuntu release remains supported.
Choose a desktop environment before installing
The desktop determines how much CPU, memory, bandwidth, and graphical work the VPS must handle. Google lists Xfce, Cinnamon, GNOME, GNOME Classic, and KDE Plasma as supported choices, provided their session and display-manager configuration is correct and 3D features are avoided.
Free tools Windows power users keep installed
One-click scans. No signup required.
| Desktop | When it fits | Important considerations |
|---|---|---|
| Xfce | Best default for a VPS, particularly over a slower connection. | Light graphical interface, few animations, and a documented Chrome Remote Desktop setup. Install XScreenSaver to avoid the Light Locker blank-screen problem. |
| Cinnamon | Useful if you already administer Cinnamon or need its workflow. | Use a session command that matches the installed desktop and avoid 3D effects. A local session may have to be signed out first. |
| GNOME or GNOME Classic | Suitable when your software or users require GNOME. | Disable or avoid 3D features and ensure the session command in the Chrome Remote Desktop file names an installed GNOME session. |
| KDE Plasma | Suitable for an existing KDE-based environment. | Configure the correct session and avoid unsupported 3D acceleration. Display-manager conflicts can stop the remote session from starting. |
If you have no strong preference, choose Xfce. It is the documented low-overhead option for slower links, not a claim that it has a particular memory or latency benchmark. Official sources do not publish a general CPU, RAM, bandwidth, or latency benchmark for Chrome Remote Desktop on a generic VPS.
Install the Chrome Remote Desktop host package
Connect to the VPS over SSH as the user who will own the remote desktop session. The following repository method is Google’s documented approach for an amd64 Debian-based host.
-
Install Google’s signing key:
curl https://dl.google.com/linux/linux_signing_key.pub | sudo gpg --dearmor -o /etc/apt/trusted.gpg.d/chrome-remote-desktop.gpg -
Add the stable Chrome Remote Desktop repository for amd64:
echo "deb [arch=amd64] https://dl.google.com/linux/chrome-remote-desktop/deb stable main" | sudo tee /etc/apt/sources.list.d/chrome-remote-desktop.list -
Refresh package metadata:
sudo apt-get update -

sudo DEBIAN_FRONTEND=noninteractive apt-get install --assume-yes chrome-remote-desktop
DEBIAN_FRONTEND=noninteractive matters on a headless VM because there is no directly connected keyboard from which to answer the layout question. If you prefer Ubuntu’s package-file method, Canonical documents downloading chrome-remote-desktop_current_amd64.deb and installing it with:
sudo apt-get install --assume-yes ./chrome-remote-desktop_current_amd64.debUse one installation method, not both. If the package URL or supported release has changed, follow the current vendor instructions for that release.
Install and configure Xfce
For a new, efficient session, install Xfce and the supporting packages Google specifies:
sudo DEBIAN_FRONTEND=noninteractive
apt install --assume-yes xfce4 desktop-base dbus-x11 xscreensaverThen tell Chrome Remote Desktop exactly which session to start:
sudo bash -c 'echo "exec /etc/X11/Xsession /usr/bin/xfce4-session" > /etc/chrome-remote-desktop-session'Disable the LightDM service so it does not compete with the Chrome Remote Desktop session:
sudo systemctl disable lightdm.serviceThe xscreensaver package is intentional. Xfce’s default Light Locker can leave a Chrome Remote Desktop connection at a blank screen that cannot be unlocked; XScreenSaver avoids that documented failure mode. The optional task-xfce-desktop package installs a fuller Xfce application suite, but it is not required for the basic remote session.

Do not enable desktop animations or 3D effects on the VPS. Chrome Remote Desktop’s Linux host does not support 3D graphics acceleration, and such features can prevent the service from starting rather than merely making it slower.
Configure an existing desktop with a per-user session file
If the VPS already contains multiple desktop environments, use a per-user file instead of replacing the system-wide configuration. Chrome Help documents $HOME/.chrome-remote-desktop-session. The command in that file should be based on the Exec= line in the selected desktop’s .desktop file.
Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Clear out junk files and repair common Windows errors3Fix the driver behind crashes, sound loss and screen glitchesFor example, a Cinnamon session can be written as:
exec /etc/X11/Xsession 'gnome-session --session=cinnamon'The exact command must match a desktop environment actually installed on the VPS. Copying a session name from another distribution, or leaving a stale GNOME/Cinnamon command after uninstalling that desktop, produces a service that starts and immediately exits.
Some desktop environments do not permit more than one session at a time. Sign out of a local graphical session before connecting, or select a different environment for the remote host. A display manager that is still controlling the console can also conflict with the headless session; use the Xfce configuration above or adjust the display-manager setup for the environment you selected.
Authorize the VPS and create the access PIN
Package installation alone does not register the VPS to your account. Authorization is performed from the Chrome Remote Desktop setup page on a local computer.
- Open the Chrome Remote Desktop setup page in your local browser and choose the SSH setup path.
- Select Begin.
- Select Next. This step tells the page that the host package is already installed.
- Select Authorize and complete the Google account authorization flow shown in the browser.
- Copy the Debian Linux command displayed by the page.
- Return to the VPS’s SSH terminal and paste that command exactly as shown. Run it as the user who should own the remote desktop, using
sudoonly where the generated command includes it. - When prompted, create a six-digit PIN. You will enter this PIN whenever you initiate a remote login.
Do not invent a different registration command from an older tutorial. The setup page generates the authorization command for the current host package and account, so it is the authoritative source for this step.

Connect from the browser
- On the local computer, open the Chrome Remote Desktop Remote Access page.
- Find the VPS under Remote devices.
- Select the VPS and enter the six-digit PIN created during authorization.
- Wait for the Xfce (or your selected desktop) session to start. The Linux desktop appears inside the browser.
The first connection can take longer than later connections while the user session and desktop services start. If the device never appears, return to the authorization step and confirm that the generated command completed successfully in the SSH terminal rather than merely being pasted.
Firewall and connectivity requirements
Chrome Remote Desktop uses its own service traffic; it is not the same as exposing an RDP daemon. Do not open a public TCP 3389 rule just because you are connecting to a desktop. Google’s troubleshooting guidance recommends allowing:
- Outbound UDP and the corresponding inbound UDP responses.
- TCP 443 for HTTPS.
- TCP and UDP 3478 for STUN.
Apply these rules to the VPS’s egress firewall, cloud security group, and any corporate or home firewall that filters the host’s traffic. A restrictive network can allow SSH while blocking the UDP or STUN traffic needed for a successful remote session, so “SSH works” does not prove that Chrome Remote Desktop has everything it needs.
Google documents encrypted sessions, but encryption does not remove the need to protect the VPS itself. Keep SSH restricted to your administration network, use a strong account password or key-based login, and treat the six-digit PIN as a credential rather than as a replacement for server hardening.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Restrict connections to a LAN or VPN
Organizations that do not want the host to use internet firewall traversal can disable that feature with Chrome’s managed policy. On Linux, create or edit:
/etc/opt/chrome/policies/managed/RemoteAccessHostFirewallTraversal.jsonSet the policy to FALSE:
{
"RemoteAccessHostFirewallTraversal": false
}With traversal disabled, plan to provide the required LAN or VPN path yourself. Test the policy in the target managed Chrome environment before deploying it broadly; a policy that is syntactically valid but applied to the wrong managed installation will not produce the intended restriction.

- Compatible with Wide Screens - To ensure compatibility with the dual monitor mount, your each monitor must meet three conditions at the same time: First, computer screens size range: 13 to 32 inches. Second, screen weight range: 4.4 to 19.8 lbs. Third, the back of the monitor screen must have VESA mounting holes with a pitch of 75x75mm or 100x100mm.
- Regarding the compatibility with desks - Your desk must meet three conditions at the same time: First, desk material: Only wooden desks are recommended, plastic or glass desks cannot be used. Second, desk thickness range: 0.59" - 3.54". Third, the bottom of the desk should not have any cross beams or panels, as this will interfere with installation. We recommend carefully checking that your desk and monitors meets all above conditions before purchasing.

Troubleshoot a blank screen or a session that will not start
Check the per-user systemd service
Run these commands over SSH as the account that owns the remote host:
The Tool Desk
Outbyte Driver Updater FREEFix the driver behind crashes, sound loss and screen glitchesFind Drivers →Outbyte PC Repair FREERepair Windows errors before they cause bigger problemsFix Now →sudo systemctl status chrome-remote-desktop@$USER
sudo systemctl restart chrome-remote-desktop@$USERThe status output can show an immediate exit, a missing executable, or a permission problem. Restart only after correcting the underlying configuration; repeatedly restarting an invalid session command does not repair it.
Read the host logs
Use journalctl to inspect the service history:
journalctl SYSLOG_IDENTIFIER=chrome-remote-desktop
journalctl SYSLOG_IDENTIFIER=chrome-remote-desktop -e
journalctl SYSLOG_IDENTIFIER=chrome-remote-desktop -bThe first form lists matching messages, -e moves to the newest entries, and -b limits the view to the current boot. Look for the first error after a connection attempt rather than only the final “session exited” message.
Fix a blank screen
- Confirm that Xfce is installed and that
/usr/bin/xfce4-sessionexists. - Confirm that
/etc/chrome-remote-desktop-sessioncontains the Xfce command shown earlier, or that the per-user file contains the correct command for your chosen desktop. - Install
xscreensaverif you are using Xfce, because Light Locker can produce an unlockable blank display. - Disable the conflicting LightDM service when following the system-wide Xfce setup.
- Remove unsupported 3D effects and animations.
Fix an immediate session exit
- Open both
/etc/chrome-remote-desktop-sessionand~/.chrome-remote-desktop-session; a per-user file can override the system-wide choice. - Ensure the command names a desktop environment installed on this VPS, not one copied from another image.
- Check the
Exec=line of the selected desktop’s.desktopfile and use the corresponding Xsession command. - Sign out of any local session if the desktop supports only one active session.
- Restart the service and immediately inspect the current-boot journal.
Fix a host that never appears online
- Verify that the authorization command from the setup page completed without an error.
- Check the service status and journal before changing firewall rules.
- Confirm outbound UDP, HTTPS 443, and STUN 3478 traffic at every firewall layer.
- Make sure you are viewing the same Google account’s Remote Access page that authorized the VPS.
Operational choices and trade-offs
For a single administrator who needs occasional GUI access, Xfce plus the system-wide session file is the shortest path from a blank Debian or Ubuntu image to a usable browser desktop. It minimizes graphical overhead and avoids the heavier session-management issues that can accompany full GNOME, Cinnamon, or KDE installations.
Use a different desktop when application compatibility or an established team workflow matters more than graphical overhead. In that case, keep the session command explicit, disable 3D features, and test whether the desktop’s display manager allows a headless, single-user session. The choice is about compatibility and resource use; no official source establishes a universal performance ranking or VPS size for these environments.
