[oe] Antwort: Re: Antwort: Re: [meta-qt5] Building and running issues on Raspberry Pi

[Stephen Arnold]

I haven't really played with this end of rpi graphics much, but here are a
couple of things to check.  The vc-graphics, vg-graphics-hardfp, and
userland packages are all involved in rpi graphics.  The first two conflict
with each other, and there appears to be init scripts involved.  It looks
like maybe both userland and one of the vc-graphics packages are required
and some initial load/init stuff has to happen?  That's about all I got,
please post if you get it working.  My rpi build has nice working audio but
it would be cool to have full graphics support...
