Continuation of rpi effort and how to test

Also will leave this here: https://github.com/anholt/mesa/wiki/VC4-Performance-Tricks might be an idea to look into. (that's the mesa driver)

You're an absolute wizard, @mariogrip - thank you so much for doing this. I've already downloaded the image and will try it out tomorrow.

This has been tested on rpi3, but should work on anything newer then 3 (as it needs arm64)

does this mean it can be installed to pinebook? thanks...

@jezek

No. Bespoke ARM images can only be installed to their target devices. Similarly to phone images.

so, it is possible, but there needs to happen some porting magic?

@jezek We have images here that are designed for the pinebook https://ci.ubports.com/job/rootfs/job/rootfs-pinebook/ but please note that these are really early images, so they are not stable at all, and there is some bugs

@mariogrip so I tried again ( I still don't know why those links works) and this is my PR with this diff

Link to Bug report about Rpi4

Good to see great progress.
Using the latest image the Pi4 boots and runs well although a graphics issue means that you can't read anything opened in a window.
Scaling is now sorted on the monitor and when using the 7 inch touch screen.
The graphics issue does not affect the Pi3 but it is (understandably) frustratingly slow.
The touch screen worked on the first image but not on the most recent one. UPDATE It woked after a reboot but as the left and right edges are slightly offscreen it restricts its usefuleness.
UT on the Raspberry Pi feels much closer now to something that will work. Thanks to those who understand all this far more than me for putting the work in.

Hello,

Trying v66 on RPI4B 4GB flashed on SDCard with dd command :

Connected to 1920x1080 screen through HDMI0 => ok
Need to disconnect/reconnect radio interface for keyboard/mouse
Overscan is always activated : ~48 pixels/lines black borders
First and second boot : horizontal view, initial parameters, keyboard layout ok
Third boot login : rotated, after login : switched to horizontal by itself
Third boot : wrong keyboard layout (uk instead of previous fr selected)
Ethernet connected but not seen, WiFi activated, Bluetooth not found
After third boot, shutdown makes a restart, not a shutdown
Next time, the shutdown was complete

Main problem :

The window manager displays the frames and menus correctly
The application show a correct initial display for one second
Then, the inner part of the window becomes garbage
It reminds me something like incoherent window size and viewport size

Rotated login

Calc just started (correct)

Calc after one or two seconds (garbage)

Multiple apps : all garbage, menu and notification : all clean

Best regards

To remove overscan, uncomment this line

disable_overscan=1

in /firmware/config.txt

If your mouse lags, try to add this :

usbhid.mousepoll=0

at the end of the line in /firmware/cmdline.txt

Another tip : print screen key works
Easy to access to the snapshots by reading the SDCard on my desktop
Will use it next time instead of the ugly pictures above ... Here is a reduced to 720p example :

Maintaining the Super (Windows or Apple) Key displays the available shortcuts. They work AFAIK.

Unfortunately, I was looking for CTRL-ALT-F1 and CTRL-ALT-F7 shortcuts but they don't seem to exist, do they ?

As said above ethernet is not seen (in the notification area) however ethernet is working !

So, one more tip if you want : ssh works too
On your desktop/laptop, use the following command in the /firmware folder of the SDCard

touch ssh

After booting, you can login from your desktop/laptop with

ssh phablet@[local-IP]
password: phablet

Have a nice evening

@Pulsar33 the CTRL-ALT-F1 and CTRL-ALT-F7 I confirm they don't work

Pulsar33

Hello,
Is there some progress about graphical problem for Pi4 ?

Hum, seems to regress.
Tried the #77 and I've a black screen after the boot listing and reboot.
However ssh works but don't know what to do with it.

@Mark The work on preparing UT apps for other arm64 platforms gives us something to work with now. The UT Tweak Tool seems to work reasonably as does TELEports and File Manager. I can get sound output from the terminal but not through the apps. Mouse behaviour is a little odd and seems to deteriorate - most of my experience is on the Touchscreen which seems more stable and easier to use. Adding Swap has been helpful, particularly when having multiple open tabs on the Morph Browser. If someone can get to the bottom of the (compositor?) issue with the Pi4 the resource related issues should be much reduced, particulatly with the 2 and 4 GB versions.

Mark

Would the approach taken here (with Gentoo running arm64 including camera, sound and display) work for us or is it too far from the way UT works? https://github.com/sakaki-/gentoo-on-rpi-64bit

There has been a lot going on but it is only recorded in the Telegram group. https://t.me/UBports_pi
The Pi3 is working fairly well (with swap) although sound and wifi are still issues and selection (without a touch screen) has its peculiarities. Morph browser and Dekko email seem pretty stable, Terminal works a treat for installing click packages built for Arm64. Running update and upgrade mostly brings improvements but might break it so consider making a backup.

Here is what is in the Telegram pinned post:
Installing Ubuntu touch is pretty easy. The default login is phablet as is the password. It should just login itself but you will need that when using the terminal for things requiring sudo or when changing some settings in the GUI. If you can use an ethernet cable at the setup stage it avoids any wifi issues (that are being worked on). Selection by mouse is a bit buggy still, sometimes selecting with "Tab" then hitting "Return" will be easier.

Download an image from https://ci.ubports.com/job/rootfs/job/rootfs-rpi/

After image #90 (15th December) there was a change which meant that the Pi 4 graphics were broken not just on windows but on the login screen (it works but you can't see that it works on a monitor) - keep trying newer images as that will eventually be fixed. This is not a problem for the Pi 3.
Feel free to experiment with newer images and let us know your experiences but there may not be someone else to compare notes with yet.

Flash SD card:
Use DD in the Linux terminal or on windows https://www.balena.io/etcher/ to write the image to the sd card once you have unzipped it. Raspberry Pi sites will give details of how to do all this.
Remember to expand the main partition to fill the card. Easiest to use a card no bigger than 32GB.

Swap:
It works better with swap. Type sudo apt-get install dc dphys-swapfile in the terminal if you want a swap partition of 2GB

Development:
https://gitlab.com/ubports/core/rootfs-builder-debos and the multiple deb packages that are used are built on ci.ubports.com with the source on github.com/ubports/

Apps:
https://forums.ubports.com/topic/3323/arm64-apps-and-testing is a good place to start when looking for arm64 apps and how to install and test them.
Some of the arm64 apps being tested for the pinephone and other arm64 devices work, others just shut down or behave oddly. Openstore is getting more arm64 architecture apps.

Sound is not sorted yet and neither is the Pi camera. However the Pi touchscreen works. Expect bugs and crashes - we are at an early stage. Probably more Alpha than Beta testing but things are developing quickly. Wifi pretends to work but ethernet works well. Have fun and please use the UBports forums, Github or associated Telegram groups to learn more, to give feedback or to help solve bugs or other issues.
