Support Ubuntu core #21

rzr · 2021-03-10T10:41:19Z

Feel free to test current snap package at:

I suspect some issues with audio or startup, testers feedback welcome.

snap maybe be restarted to show up This could be improved with GLES port to drop GLX dep and then xwayland to use SDL2's wayland backend. cmake trick might be fixed upstream too Change-Id: Iced9c4f250254b78ce8ae12c295ecb21c0133c8f Relate-to: #21 Signed-off-by: Philippe Coval <[email protected]>

I have observed that Ubuntu core-20 installs to /usr/local so this should be updated Relate-to: adoptware/pinball#21 Signed-off-by: Philippe Coval <[email protected]>

If you want to test on virtual machine as explained at:
https://discourse.ubuntu.com/t/getting-started/19737

Then just run:

snap install --candidate mir-kiosk ; snap info mir-kiosk
snap install --edge pinball ; snap info pinball
snap list

It works using software rendering:

Some warnings should be investigated, though

sudo journalctl -u snap.pinball.daemon

Mar 11 10:19:24 ubuntu pinball.daemon[2618]: >                   X11 cannot support keycodes above 255.

I also tried on RPi3 but there is a rendering issue/freeze in table modes
(I suspect something odd in offscreen swap rendering)

Have you considered using stage-snaps: [mir-kiosk-x11] as described in https://ubuntu.com/tutorials/x11-kiosk?

rzr · 2021-03-15T11:16:04Z

Thanks @AlanGriffiths

Yes this works too but I wish window to be displayed fullscreen this is the reason I kept using i3 hack from

https://github.com/MirServer/xwayland-kiosk-helper/blob/master/xwayland-preload/xwayland-kiosk-launch

May this launcher be merged into:

https://github.com/MirServer/mir-kiosk-x11-snap/tree/main/env-setup/hacks

Anyway I didn't want to use X11 in the first place
but wayland since this project is using SDL2 and it is working fine on ubuntu classic see this video clip on RPi3 :

https://youtu.be/4Ja4TNmBSFc?t=46

But for some reason using wayland launcher for Mir does not display anything,
while log did not look suspicious, any hints welcome?
(Is Mir stack supporting legacy opengl or only GLES ?)

If interested to replicate this issue I'll open a ticket and push a branch.

Yes, SDL2/Wayland works on mir-kiosk/Ubuntu Core/RPi3. See, for example, mir-kiosk-neverputt,

But for some reason using wayland launcher for Mir does not display anything,
while log did not look suspicious, any hints welcome?

https://ubuntu.com/tutorials/wayland-kiosk

(Is Mir stack supporting legacy opengl or only GLES ?)

Mir is irrelevant here. The kernel graphics stack on Ubuntu Core is the same as on Ubuntu Classic. But you do need to include the Mesa userspace libraries in your snap as described in the above tutorial.

If interested to replicate this issue I'll open a ticket and push a branch.

From what you said, it seems likely the issue is in your snap.

Current snap works fine on qemu using wayland-launch

Menus are displaying fine on RPi3 (with this fullscreen option:
23fba2b)
but play mode might suffer some locking or double buffer issues, I didn't investigate yet.
But I noticed that while playing the table can be refreshed if paused and resumed (hit Esc, select play).

Note that the ubuntu classic image is working as expected on Pi3 but it uses weston compositor not Mir.
it can be downloaded from #16
Soon or later I'll trace the rendering part to compare with real x86_64 machine.

For portrait display I am tracking this Mir feature:
canonical/mir#1643

Refactor a bit, add Period to optimize FPS division It was also tested in Ubuntu-Core on Pi3 at 0.30 FPS Using VC4 V3D 2.1 backend from GL 2.1 Mesa 20.2.6. While Ubuntu classic on weston is way faster, I'll may check again with Mir on next classic Release.

Fix perf issue, resetTick before looping The other one may be removed but I am not sure yet. Tested on Pi3 it's about 12fps with ubuntu-core: PINBALL_SPEED=100 PINBALL_TABLE=professor sudo snap -R run pinball Renderer : VC4 V3D 2.1 Version : 2.1 Mesa 20.2.6 Signed-off-by: Philippe Coval <[email protected]> Relate-to: #21 Change-Id: I24174b4961dcb36c49dddfed834aca9f3a1439d2

Some updates on Pi4, it work pretty fast on default config (landscape view) it's about 40 fps with prof table.

Hi, Some updates about this effort

I built a demo image (on worst table) for amd64 (it works with virtual box):

curl -O https://bashupload.com/ZLYFb/cfep0.gz#./file/pinball-table-hurd-core20-amd64-pc.img.gz

It's super easy to rebuild using this helper makefile:
https://github.com/rzr/pinball-table-hurd/tree/master/snap/image

More investigations should be done for Pi3 or Pi4
(I need a UART cable to troubleshoot):

https://forum.snapcraft.io/t/built-uc20-rasperry-pi-image-hangs-on-boot/23891/19?u=rzr

BTW, I'll present those works at next LibreGraphicsMeeting 2021:

Last but not least, I proposed this as an appliance:

For portrait display I am tracking this Mir feature

I'm not sure what you mean. That PR landed last year, long before you decided to "track" it.

rzr · 2021-05-10T12:03:44Z

Yes I confirm portrait works in mir,
Thanks @AlanGriffiths for that.
I've been using it in "gnu" image, I'll push changes soon.

Display should be rotated manualy using: sudo snap set mir-kiosk display-config=... I an wondering how can this be done in images without duplicating gadget snap.
