OpenCPN on Rpi bookworm

[geoffr]

A new OS version (bookworm) has been released. Has anyone tried it out with OpenCPN?

Wondering if it's worth the update on my CM4...

Yes,
with the latest updates it works well.

I'am also using other OS versions on the RPI4. Ubuntu Lunic Lobster, Debian Bullseye, Bookworm and the latest Fedora 39 beta. All run very well on the RPI4. Fedora on the CM4.


However my CM4 memory has only 16 GB is, which is too small for all the applications. I have to remove several applications.

Fedora runs very well with the latest kernel version 6.5.6. Fedora is backed by Redhat/IBM.

All working with OpenCPN and the SignalK server software.

A new RaspiOS V5 is released and based on Bookworm.

Can be installed from the internet. Just did allready some tests.

All the applications I use, works. Flatpak enviroment, NPM, the SignalK server software. OpenCPN flatpak version 5.8.4-2. Oesenc Charts with the O-charts plugin.

GPS data from the SignalK server.

Not all is perfect but it works.

verkerkbr - not all is perfect ... is anything broken? Is there better performance? (Wondering if there is a reason to upgrade, or should I stay with what is working?)

[verkerkbr]

The Bookworm worked well for me with the Flatpak OpenCPN version.


Nowt rhe RaspiOS V5 on the basis of Bookworm was easy to install from the internet


With NPM, flatpak install, SignalK and OpenCPN 5.8.4.2.


But now I have problems with this OpenCPN version. The O-charts plugin does not seem to work well. Setup sometimes closes system.


Local ENC charts works well


I think it is not yet ready for daily use. It is too early for regular use.

But now an upgrade has arrived. All problems seems to be gone. The RaspiOS V5 on the basis of Bookworm works now very well and fast.

O-charts plugin and the Oesenc charts works without any problems and verry fast.

Thanks - I'll wait

I also tried out Bookworm generally it works fine however the biggest disadvantage for me is that RealVNC doesn't work anymore (due to wayland WM). You have to get sth like TigerVNC, which works, but then you have two have VNC Clients if you wanna use Bookworm and Bullseye in parallel...

So I'll wait, too.

Yes, the only missing Item is de VNC server. Tried to install the OpenPlotter extra's.

The installation seems to go well. But the OpenPlotter setup does not start

It is still eartly days with a new RaspiOS based on Bookworm.

But otherwise it works very well with fast screen movement.

It is a big improvement over Bullseye.

I have the same problem with Ubuntu and Fedora also with the missing VNC server.

This is what the VNC organisation declared:
Statement

Our current versions of RealVNC Viewer and RealVNC Server unfortunately will not support the RPi 5 platform out-of-the-box as a result of Raspberry Pi’s move to a default Wayland environment on Debian (Bookworm).
RealVNC has enjoyed being the remote access vendor of choice for the Raspberry Pi platform and of course we’re disappointed that the new stack precludes us from maintaining continuity there just now. It’s worth noting that RealVNC Connect will, of course, continue to work on all versions of Raspberry Pi and PiOS prior to the latest RPi 5 and Bookworm.
We value our partnership with Raspberry Pi highly and we’re broadly supportive of the roadmap items required to see us back on the platform as default remote access provider in short order. Without providing an exact committed delivery date, we are happy to say that we’ll be back up and running on RPi 5 during the first half of 2024.
More generally, we see investment in Wayland support as strategic for the future of our wider Linux base – not just Raspberry Pi – so it’s very much on our radar and you can expect more news early next year.

If you use RealVNC viewer 7.7.0 you can connect easily with bookworm, even if you use Wayland (at least on my Mac). I do have more problems with the flatpak OpenCPN and Wayland, but if you revert to X11 it works perfectly well again.

I got my new Raspberry 5 and had to move to "Bookworm".

Standard on "Bookworm" seems to be the "wayland" back-end instead of X11.
OpenCPN behaves a bit erratic when running on Wayland, e.g. the toolbars always stay on top, so, if you e.g. want to run a web-browser, the toolbar overlays the web-browser. The small toolbar on the right lower corner disappears, when you move the mouse over the chart (it can be restored, when clicking on a "nil" tab on the launch-bar though).


As I believe, that "Wayland" will be the future back-end on Debian, maybe somebody of the developers has a look into this.


For the time being you can switch back to X11 (sudo raspi-config and on the advanced options A6 this can be accomplished).



To be honest, I liked the handling of "Wayland" much better than X11, especially the laundh-bar is easier to handle. etc.

Is there an updated step by step install guide for Rpi Bookworm?

Neither of these seem to work:

Uwe...


Current OCPN dev thinking is that these display errors are resulting from RPi's implementation of XFCE Display Manager.
Logic:
1. OpenCPN does not talk directly to the system display manager. All interaction is through wxWidgets, and his internal management of DM.
2. Other GUI apps (e.g. CLion) have assorted minor display trouble with XFCE.


Conclusion: XFCE not quite compatible with Wayland.
We hope that the RPi and XFCE devs are looking into this, because I too would like to move to Wayland if possible.


Thanks

Dear Dave,



thanks a lot for your answer. I think we will have to wait how thongs will develop, There are more flaws with the implementation of Wayland, whether it is just Wayland or anything around, e.g. "Screen Blanking" with Wayland the screen goes dark (as it should be) but only for a moment, when a "Login Screen" pops up and the Screen is no longer dark and remains in this "Login Wait", etc.


For the time being I am content to switch to X11, it runs stable, OpenCPN works well , no hassle. The Pi 5 IS fast, but the side effect is a doubling of power consumption AND not to forget no Audio-Jack Why this was taken away but a second HDMI socket... I have no idea. There must be people looking stereo on this tiny machine ...


Anyway, I see, you are aware (as I suspected ) - thanks a lot to you and all you folks, helping us with such a great product OpenCPN ...


Best regards,


Uwe
