--- Comment #1 from Max Staudt ---
Okay, so there are two things here.
Let's look at the latter case first: When you blacklist vc4, you'll be using
efifb. For some reason, the red and blue channels are currently inverted. This
is already on the kernel leven (efifb itself), and I'll have to have a look
into it.
As for when vc4 is enabled, you're running out of memory that's usable by that
driver. We're very short on it at the moment, as CMA is not enabled in the Leap
42.2 kernel (CCing agraf, he knows more about this, and will correct me if I'm
wrong).
Why are we running out of memory? Well, this happens when somebody is using the
3D graphics functionality of vc4. This can happen when GLAMOR is enabled (it
shouldn't in the Leap 42.2 image, but I haven't checked). We currently don't
support 3D on the RPi because of this, but we hope to be able to do so at some
point in the future. For now, vc4 is still under heavy upstream development.
So for now:
1. Please un-blacklist vc4, and then
2. Can you please attach /var/log/Xorg.0.log to this bug, so we can check for
GLAMOR in your setup?
3. Can you please post the output of
ls /etc/X11/xorg.conf.d/
