Raspberry Pi 4 Model B

@Aury88 sorry, I didn't read the whole thread, just from the point you pinged me.

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

@alan_g thank you.! I will try that.

Hello
Don't know what to do.
And you ?

No @Pulsar33, we mortals are all stuck with the compositor error. also I can access only the first time to the session. it asks to set a name to the device but in the following boots, after login (with phablet or the chosen name is the same) it start a wrongly orientated login interface without keyboard recognition and the impossibility to use the virtual keyboard due to the compositor problem.... also I am not able to access the console mode

Pulsar33

Thank you for the answer
Is your build the last successful one #44 created today ?
I can't test it before a few days but I will asap

@Pulsar33 yes. the #44 have a working GUI (but still not the compositor).

Aury88

Warning!: the last rootfs-rpi build (#51) has not the GUI.
Here the cat /.cache/upstart/unity8.log pastebin

Hello,

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.

@Pulsar33 to me it seems more like throwing a stone in the pond and then shouting "there is movement !!"
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 )

I know this is about the Raspberry Pi 4 but if any of you, frustrated with the lack of progress, have a Raspberry Pi 3 you may want to try that as it is working reasonably well but with bugs that could do with some attention. 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.

@Mark Brian Douglas now has an experimental open store for multi arch which worked well for me on the Pi. The Telegram UBports Raspberry Pi group is a good place to follow progress.

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.

@pulsar33 just before I do delete these, can you not do it yourself? As the poster if you click on the three verticle dots on the far right is there not a delet option?

Pulsar33

@lakotaubp This is what I tried to do for the first one, and it became greyed but was still present.
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.
Sorry to ask you to do this for me

PS : I've just tried once more to delete the two messages above and they are now greyed but still displayed

Lakotaubp

@pulsar33 Yes I think you can see them as you posted them as can the mods but no one else. If you can see a Purge optionin the dot menu use that and they should be totally gone

Pulsar33

@lakotaubp Unfortunately not, I only have the Edit, Restore and Signal functions for those I have "deleted". Please do what you consider best for these messages, thank you.

AS this thread is two years old I am going to lock it. If anyone does want to carry on with a similar topic please start a new thread and if you need to link it back to this one. Thanks.
