UT on Raspberry Pi 4 Model B

You can try the rootfs-rpi, done by Marius; To write the image on a SDcard you can use etcher (https://www.balena.io/etcher/) or, after unziped the file and unmonted the SDcard, the bash comand dd:

lsblk      # the SDcard appears as /dev/sdc or /dev/mmcblk0
umount /dev/[sdcard_subpartition_name] #you have to umount every subpartition in the sdcard like sdc1 sdc2..for this you can also use GParted.
sudo dd bs=4M if=ubuntu-touch-raspberrypi.img of=/dev/[sdcard_name] status=progress

The image is reported to work correctly on SDcards with >=8GB and <=32GB

The login and password in console mode are both the string phablet

If you have only the console mode you can change the default keyboard layout in /etc/default/keyboard by editing the line XKBLAYOUT="xx" (change xx with your language code eg. it for Italian or es for Espagnol )

The Ethernet and the wireless connection are reported to work (from build #63) while bluetooth don't seems to work

With the actual jenkins build image you can access the GUI but with issue on the apps visualizations (the unity log in this case can be seen here). this could be related to a compositor problem

Thinking there was a problem, I used an option such as "restore" (don't remember the exact expression) and then I posted the second one.

I know that my colleagues at Canonical have yet to get graphics working on the Pi4 with Ubuntu Core (I think that's lack of time, not a technical issue)

Update: I just read the phrase "note: this fixes mir-kiosk support !" on this snapcraft thread about the Pi4:

https://forum.snapcraft.io/t/support-for-raspberry-pi-4/11970/37

That implies a kernel which works with Mir graphics and therefore can support Unity8.

The Telegram UBports Raspberry Pi group is a good place to follow progress.

Solving them should, in many cases, also help with the Pi 4 once the (compositor?) bug is fixed. Some of the existing UT apps have been recompiled for arm64 so we have working file manager and UT Tweak amongst others. The Telegram group has instructions to add Swap which makes life a lot easier.

but that was a right move...maybe someone from there can help us port UT on RPI.
here the situation has stopped (not to say worsened since we lost the GUI operation ...and we don't know why 😖 )

Things are moving on the raspberrypi.org forum. An Ubuntu sub-forum has been open in Operating System distributions / Other and an old thread about Unity has been updated. A few members are posting.

That log isn't related to https://github.com/MirServer/mir/issues/704 where one of the DRM functions returns a misleading result. Instead it looks like the graphics driver isn't adequately supported by Mesa.

I know that my colleagues at Canonical have yet to get graphics working on the Pi4 with Ubuntu Core (I think that's lack of time, not a technical issue). But maybe you can find something useful here: https://forum.snapcraft.io/t/support-for-raspberry-pi-4/11970

For example:

you might need to play with the dtoverlay= kms or fkms values in config.txt. i know the vc4 driver isnt fully ready to drive the vc5 hardware in the pi4 but i know that for example my omxplayer-pi snap works fine (only 1080p though, omxplayer does not support h265 yet) when either using no dtoverlay or with the fkms one (not with the kms one though). - https://forum.snapcraft.io/t/support-for-raspberry-pi-4/11970/17

Hi Alan!
The unity8 log pastebin was already linked in the first post of this thread. Sorry I thought that it was convenient to put it there. Here the link to the unity8 log pastebin.

@Pulsar33 for the unity8 log you have to do this:

cat /.cache/upstart/unity8.log
