Failed to load /usr/bin/libGLESv2.so: Error loading shared library /usr/bin/libGLESv2.so: No such file or directory

That file is part of mesa-dev (see package search) does it work when you install that package?

Usually, a dev package should not be required at runtime of such a program. Maybe the file is just a symlink (and we can patch the Angelfish browser to run without it), could you check if it is a symlink as well?

Thanks a lot! I will try this as soon as I have solved https://gitlab.com/postmarketOS/pmbootstrap/issues/1664 so that I have enough space to install mesa-dev.

It still does not work:

Maybe some opengl features are not implemented in the freedreno driver but required for angelfish?

Or maybe Qtwebengine was compiled with X11 instead of wayland?: WebEngine compiled with X11 support, however qpa backend is not xcb. This may fail

According to this QtWebEngine does not have an actual Wayland port. Not sure if this is the cause. They also say that it should work with xwayland installed. I will also try starting the app directly under X11/Xwayland: "QT_QPA_PLATFORM=xcb angelfish".

https://github.com/qutebrowser/qutebrowser/issues/2932

According to this It might be a problem in mesa, although the fix is supposed to be committed since 2014, so I doubt we don't have this commit already included.

https://forum.qt.io/topic/67460/eglcreatepbuffersurface-failed-with-error/2

According to this it may be related to non-sported "Pbuffer surfaces" by graphic driver and it may be fixed in qt 5.11. So We would need to update qt in order for it to work, not sure how hard this would be.

Thanks for all the research! Looking forward to hearing if that works (if it does, we could export that variable by default like you already did it with the improved touch keyboard)

Great news:

*It runs with this option! ("QT_QPA_PLATFORM=xcb angelfish")

*Zomming and grabing are very smooth and neat! (way better than midori)

Bad news:

*It crashes very very often (including at startup).

*The keyboard does not show up! (like in all X11 app I've tested now, maybe there is a parameter in xwayland?).

*The top bar is very small. There is maybe a problem with pixel ratio or fontsize with X11 Apps, because they all display very small. (Don't know if there is an option for that in XWayland)

So it is not usable for now.

Example of a session ending up with a crash:

Action plan:

*Package Qtwebbrowser to see which part of the problems is due to angelfish and which is related to qtwebengine.

*Reach plasma-mobile team to know with which options, their apps is supposed to be used (Wayland? X11? Qt5.11? )

*Study XWayland options, to see if we can improve situation concerning pixel-ratio/fontsize and keyboard ( Will benefit also other X11 apps )

*Upgrade to Qt 5.11.1

I really hope that the instabilities does not come from the freedreno driver, because I cannot do anything about it.

To be done in an unknown amount of time, and I will first need to learn more about Alpine packaging & compiling.

@jbbgameich made this aport and worked on the source, maybe he has some ideas on what's going on here?

By Bart Ribbers on 2018-09-18T10:03:31

Ilya Bizyev verified that Angelfish works on wayland some weeks ago, but he used a Debian based image with Halium (https://twitter.com/IlyaBizyaev/status/1035860245476769792). I'll ask him if he used any special patches for QtWebEngine and reply here again.

By Jonah Brüchert on 2018-09-18T18:12:42

@JBBgameich Thank's a lot. It would be interesting to know which version of Debian he used, because testing has qt 5.11.1 while stable has qt 5.7.1. It sounds possible, given the links above, that qtwebengine works with Wayland only starting from qt 5.11 .

Ps: I also realize seeing his video that we are lacking keyboard icon that he has on the top left and corner (that's a shame it would be usefull with some apps).

By Pierre Parent on 2018-09-18T19:20:02

If I start the app with

"QT_QPA_PLATFORM=xcb QT_SCALE_FACTOR=4 angelfish"

The menus and top bar are at the right size, but the content of the page is too big and I can't zoom out...

By Pierre Parent on 2018-09-18T19:49:55

Great progress \o/

Maybe we would need to build wayland support into qt5-qtwebengine? Currently, that package comes from alpine.

@JBBgameich: could you link us to how qtwebengine is built in the Halium image that was used in the twitter video?

Nope, we have qt5-qtwebengine forked with Luna specific patches here. That said, it's $pkgrel is behind upstreams, so I guess Alpine's gets installed anyway. I've tried bumping our version but some of the patches don't want to apply anymore, I'm not sure how we ever got it too 5.10.x.
