quick question...is there a possibility to accelerate the graphics output for a Raspi 3? There is a package X11-raspberrypi, but that seems not to contain any drivers or hints

To answer my own question: I stumbled over xf86-video-fbturbo, which seems to offer what I'm looking for:

Hardware accelerated window moving/scrolling on Raspberry Pi (using the BCM2835 DMA Controller)

hwinfo | grep bcm2835 gives a bunch of entries

In fact loading the module fails:

raspi:/home/test # insmod /usr/lib64/xorg/modules/drivers/fbturbo_drv.so insmod: ERROR: could not insert module /usr/lib64/xorg/modules/drivers/ fbturbo_drv.so: Invalid module format

Any idea what this means, or how to solve it? Or is ist the wrong driver at all?

Hm, that's strange. Do you boot a custom kernel? I asked our graphics specialist Patrik (in CC) and he told me the following: <paste> To enable 3D acceleration you need to: 1) Install Mesa-dri-vc4 package 2) Edit /etc/X11/Xorg.conf.d/20-kms.conf and remove the line: Option "AccelMethod" "none" This will enable Mesa 3D acceleration and 2D acceleration in X with Glamor. Previously we had a memory leak but when I tried this on Tumbleweed (today) the leak seems to be gone. Perhaps the leak is still present in Leap. Also, there is an issue with Glyph rendering so some chars in text is missing. Your mileage may vary. </paste> Maybe you want to give this a try.
