Hello all,

How can I enable graphics acceleration on qemux86-64? My image is using wayland with weston and the GUI is not exactly fast.

* When I do `runqemu slirp kvm gtk`, it throws the following error: `runqemu - ERROR - Failed to run qemu: qemu-system-x86_64: Display 'gtk' is not available.`
* `runqemu slirp kvm sdl` works, but the weston GUI does not seem to be accelerated.
* `runqemu slirp kvm sdl gl` emits the following: `runqemu - ERROR - Failed to run qemu: qemu-system-x86_64: OpenGL support is disabled`

Below I'm posting a snippet of `poky/scripts/runqemu` to have at hand the qemu options enabled by the runqemu options mentioned above:
```
            elif arg == 'sdl':
                if 'gl' in sys.argv[1:]:
                    self.qemu_opt_script += ' -vga virtio -display sdl,gl=on'
                elif 'gl-es' in sys.argv[1:]:
                    self.qemu_opt_script += ' -vga virtio -display sdl,gl=es'
                else:
                    self.qemu_opt_script += ' -display sdl'
            elif arg == 'gtk':
                if 'gl' in sys.argv[1:]:
                    self.qemu_opt_script += ' -vga virtio -display gtk,gl=on'
                elif 'gl-es' in sys.argv[1:]:
                    self.qemu_opt_script += ' -vga virtio -display gtk,gl=es'
                else:
                    self.qemu_opt_script += ' -display gtk'
```

Kind regards,
Manuel

Hi Alex,

Something in your custom setup disables opengl in qemu-system-native.

Can you try core-image-weston with plain poky only?

This is the test we use to ensure it does work, it lists all the settings that have to be in place

(but in poky they are enabled by default, except the gtk frontend):

http://git.yoctoproject.org/cgit.cgi/poky/tree/meta/lib/oeqa/selftest/cases/runtime_test.py?h=master-next#n165

Interesting. Things don't work on both my Debian Buster machines.

How does opengl get set in qemu-system-native? Am Yocto novice and don't speak Python.

Am using poky repo on tag dunfell-23.0.10 = 2a848e9507.

Here's my complete test results:

* `runqemu kvm slirp core-image-weston` fails with `Failed to run qemu: Could not initialize SDL(x11 not available) - exiting`

* `runqemu kvm slirp sdl core-image-minimal` fails with `Failed to run qemu: Could not initialize SDL(x11 not available) - exiting`

* `runqemu kvm slirp sdl gl core-image-minimal` fails with `Failed to run qemu: qemu-system-x86_64: OpenGL support is disabled`

* `runqemu kvm slirp gtk core-image-minimal` fails with `Failed to run qemu: qemu-system-x86_64: Display 'gtk' is not available.`

How would I enable gtk frontend in poky?

Thanks, Manuel

`export DISPLAY=:0` did the trick.

The following shows when still on poky dunfell:

* I can now boot `runqmu kvm slirp sdl core-image-weston`. But gui is still slow. I cannot even type `systemctl poweroff` in weston-terminal, it inevitably becomes `wweesssttooo[...]`.

* `runqemu kvm slirp sdl gl core-image-weston` still fails with `Failed to run qemu: qemu-system-x86_64: OpenGL support is disabled`.

Updated to current poky master, but got this: `ERROR: ParseError in configuration INHERITs: Could not inherit file classes/image-mklibs.bbclass`.

Switched to hardknott-3.3.3 which is four weeks old and perhaps a little riper. It's currently building.

Regards,

Manuel
