Hi,

Nope, not active.

Needs -display gtk,gl=on for opengl support.

virgl is silently turned off in case opengl support is not available.
Ideally virgl should be OnOffAuto not bool, but I fear changing that
now (and start throwing errors on virgl=on if opengl is not available)
will break stuff ...
take care,
Gerd

Awesome - even on TCG the display is now nice and snappy.
For bonus points:
The AGL panel display is rotated 90 degrees which is putting a bit of a
crink in my neck. Is their anyway to rotate the view port. I tried
inverting xres and yres but that didn't do anything.

At least a warn_report maybe?

Hi,
The output is rotated, edit /etc/xdg/weston/weston.ini and comment out
transform ini entry from the Virtual-1 output section. Reboot, or
restart weston@display service. Note that the apps are optimized for
landscape.
Enabling 3D with qemu might be something worth adding in the docs.

Thanks - that seems to do the trick.
I can't find where in the agl repo that is set. The recipe seems to be in:
meta-agl-cluster-demo/recipie-graphics/wayland/weston-ini-conf/virtual-landscape.cfg
but I can't see where the "transform=270" got added.
Visually it looks a lot nicer now although I could still do with
getting rid of the quite large AGL lower banner which is cropping out
the main display.

I assume from

Yes, like I've said, but apparently I've substituted landscape w/
portrait, applications are designed to accommodate portrait orientation.
The panels, are added dynamically by homescreen.
