The Industrial Raspberry Pi Forum

Hello,
I downloaded the latest version of bookworm image and installed it into RevPi connect+.
Problem: Cannot use RealVNC Viewer to remote to RevPi
I use RealVNC to connect with RevPi but it shows grey screen in RealVNC window.
Setting in Cockpit
Enable VNC Server (VNC Control Service Enable but Failed to start)

I try to enable that in raspi-config.
And I got the problem. (I use Compute Module 3 So I choose to enable X11)
It can't be enabled and I don't know why it gives me an error.
Do you have any solution to fix this problem?

Hello Guest13, Which image did you use? If you are using the "RevPi Bookworm 64-bit Lite (01/2025)", the graphical user interface is not included. That would explain the behavior. Then switch to the "RevPi Bookworm 64-bit Default (01/2025)" image and just try it again.

I am using RevPi Bookworm 64-bit Default (01/2025) and the problem still remain. Did you have any solution for this case.

Hello Guest13,I have just activated the VNC server with the current RevPi Bookworm 64-bit OS 01/2025. I did this from the command line as always with:

Hi Dirk, I re-install the RevPi with RevPi Bookworm 64-bit Default (01/2025) from https://revolutionpi.com/fileadmin/down ... efault.zip
After installation is completed, I try to enable VNC server following your reply but encountered the same problem again.
Do you have any idea with this?

Hello Guest13,
this is nice - a reply with a YouTube video perfectly showing the erroneous behavior. Great!

The host name is RevPi right? This is the default hostname after flashing. But your RevPi device needs to be "married" with the hardware case, which means the device has to be initialized first.

Thus, please execute: If you have lost the sticker, please write down the printed password before doing a reboot, i.e. like so: Then, after the reboot, the device should be accessible by using the hostname "revpi[serial].local".
Here is a how you can find the serial number of your device.

Then please try again to activate the VNC server.

Hi Dirk,
I used sudo revpi-factory-reset and sudo reboot commands.
And try to activate the VNC server again.
But it has the same problem as the YouTube video i posted earlier.

Do you have any idea?

Hi Guest13, it looks like the vnc-server either not installed or not enablet right.
First try:
sudo systemctl enable vncserver-x11-serviced.service
sudo systemctl start vncserver-x11-serviced.service

if this doesn't work its not installed:

sudo apt install realvnc-vnc-server

Also execute the first commands again.

Hope this helps
