Hi,
I also see this errors, just when using the Armbian Desktop for Cubietruck (Desktop, Xenial, 3.4.113) out of the box.
My concern is mostly about 2D hardware acceleration for some applications - like e.g. Firefox.
If I force-eneable hardware acceleration for chromium-browser, and the application is much more responsive, and faster - not showing errors like above.
If you force-enable hardware acceleration for Firefox, you will exactly see above errors - while it will still be slow like hell (e.g. even typing the URL hangs).
The same is true for e.g. gThumb. It also shows above errors, which implies that it falls back to software rendering, and having a very poor 2D performance.
When these applications fall back to 2D/fb sw-rendering, this is normally a difference from system load of 2.00-4.50 vs. 0.75 when hw-accelerated.
So it would be really nice if such applications could also use hw-acceleration.
Cheers,
Sebi
P.S.: When I say out of the box, that's not really true, off course
- I installed lightdm, and lightdm-gtk-greeter
- I modified the video memory settings (sunxi_fb_mem_reserve=64 sunxi_g2d_mem_reserve=64 sunxi_ve_mem_reserve=96)
- I modified settings for fb0 (fb0_framebuffer_num = 4)
