It looks like something from the late 80's or start 90's when it comes to color and graphic and text - like something from the good old Commodore 64 days. Text not clear and everything running very slow. I didn't experience this with my old setup (using Raspbian and the AstroPi3 script). Am I missing something here?

Did you configure VNC viewer to use 24 bit color and best quality? Can you share screenshot?


Yep. After yet another reboot it looks good. But it's really slow. Lag on everything (even just dragging a small text document from one window to another is lagging. My Pi is placed one or two meters away from my computer. But could it be the Raspberry Pi's WiFi signal, that's not that great?

Ok, I just tried using VNC through the ethernet connection instead. That's faster, but still lagging a little bit (but it's nothing alarming). Is there a way to get the Ubuntu server to do the following concerning network connections:

1) If ethernet is connected, WiFi signal is disabled
2) If no ethernet, then enable WiFi and look for a known WiFi (eg. my own WiFi at home) and connect to it
3) If no known WiFi is found, then use the RP as an access point.

I can't even seem to figure out how to connect the Ubuntu server to my home WiFi....

I developed a script which installs all imaging software I use plus KDE by default or mate as on option.
The script and instructions are available here:
github.com/avarakin/AstroPiMaker4


I had to rebuild my imaging Pi4 about a month ago and I used the latest Ubuntu Server 19.10 images.
I updated my scripts on
github.com/avarakin/AstroPiMaker4
as part of this rebuild.
The issues I observed in the past are solved now and after several imaging sessions, I can conclude that the system is very fast, stable and reliable.
Feel free to use and/or fork and let me know if you see any issues.

Looks like the good old Ubuntu Mate distribution is still lacking support for RPi4. I don't think I will ever go there again - much safer and faster getting the images directly from Ubuntu, given that all groundwork of building the system from Ubuntu Server image is now completed.

BTW, Mate is getting really long in the tooth and I am switching to Gnome 3 on my computers.
It is running surprisingly well on RPi4.
"Dash to Panel" and "System Monitor" Gnome extensions are making Gnome work very similar to Mate.
They are included as part of my script.

Interesting, is the AstroPiMaker4 script only for the Pi4 or also for other Pi's?

I have a Pi4 running Astroberry, but also a number of Pi3B+ which I might be able to test this stuff on (if it works).

Have you thought about xrdp instead of VNC? For me RDP appears to be more responsive graphically than VNC.

I do not see a reason why it would not work - it is based on the standard Ubuntu image which supports Pi3 too.
I tried xrdp in the past but I did not like it. I also tried NoMachine long time ago, also had some issues.
I feel that given that VNC is available out of the box and always works for me , I did not try anything else recently.

Connecting to your home Wifi should be easy as long as you disable the Access Point.
Regarding the rest of your questions - Access Point of my build is based on create_ap project which is pretty popular.
I suggest reading their documentation or ask a question on their forums.
Keep in mind that it is just a shell script, so I am sure it can be easily modified for your needs.
