Has anybody else set up an RPi4 with MATE and found an easier solution? If you know of a ready to burn image out there, please let me know.

In the meantime, this approach works darn well!

Yes, but there is an unofficial image for installing Ubuntu Server 18.04 on the RPi4:

jamesachambers.com/raspberry-pi-4-ubuntu...-3-image-unofficial/

Just follow the instructions, it is entirely straightforward.

After installing the server, use the command line to install the gnome and mate desktop environments:

$ sudo apt-get install ubuntu-desktop && sudo apt-get install mate-desktop-environment

After that, tweak the system to the exact MATE configuration of your liking.

I install x11vnc, configure it with x11vnc -storepasswd, then add it to my startup preferences x11vnc -usepw -shared

I set the screen size for the vnc server also in the startup preferences xrandr --fb 1920x1080 (or the screensize you want)

Configure the wireless network for a static IP address.

You also need to edit the config.txt in the BOOT partition (!) to force the output when no HDMI is connected, else VNC will not show anything.

Indi, Kstars and astrometry.net install from there as usual.

From all I have been doing with this so far, the system behaves like any other regular MATE installation.

I haven't tested in the field yet, but the cameras work, joystick works to control the mount, I can take Darks as usual, so I do not anticipate any MATE system-related hiccups when I tried out for real as soon as the clouds disappear here again.

Let me know how it works for you.

Looks like one can get Ekos to run now on the RPi4 using Ubuntu MATE at 64 bit.

Huge improvement of the Pi3.

Did you have the 'Swap' box checked in the guiding module?

Did you check 'realign after guiding failure' and 'Always Reset Guide Calibration' set in the Ekos/Scheduler Preferences?

I haven't had the chance to check out 3.3.6 in the field yet, just installed Ubuntu MATE on my RPi4 and am now taking darks.

So far so good. Need to see how well it will behave when I program the scheduler for real.

The only thing I'm not a fan of is, that if your SD card is 64gb, then the image it creates is 64gb. It'd be nice to have something that only writes the changes I've made. That way I could reinstall the image from Stellarmate and then apply the changes in that backup.

Oh well, this works. Which reminds me, I need to do it for the new RPi4 and delete my old one, which is taking up 64gb ;)


Just compress the image.

And switch to Linux....

How do you install Ubuntu Mate on the M4? I can't see an image for it, just the RPi3 one and that doesn't work.


Start with the Ubuntu 18.04 Friendly Desktop Image and install either on the eMMC or on a micro SD card (use the fastest you can get).
Then go to Synaptic Package Manager and install all the MATE components.

Attached my install log.

Synaptic also lists the images for 4.15, 4.18 and 5.0 kernels, but I have not figured out yet how to get the Grub menu to show when the system starts.
If you could figure that out, we may me able to solve the problem.

Ubuntu MATE runs GREAT on the NanoPi-M4, very fast and installing KStars and Indi went without a hitch, works fine, except for my ZWO imaging camera, which continues to hang (the ASI120MM works, though, so this seems to be an issue with the system not being able to handle the larger data flow through the ASI1600MM).
