Board - i.MX6Q SD + "i.MX 6Dual/6Quad Linux Reference Manual" - Chapter 12 - X Windows Acceleration.
In xorg.conf, if I set "fbdev" as Driver in section "Device" - system is starting, hardware acceleration is not available.
I installed gpu-viv-bin-mx6q_12.09.01-1_armel.deb and xserver-xorg-video-imx-viv_12.09.01-1_armel.deb. The xorg.conf file has been changed - "vivante" as Driver. The content looks similar to the description in "12.3.4 xorg.conf for i.MX 6".
Unfortunately the result is different than I expected - screen is black. Also in Xorg.0.log I see some errors:
[ 161.393] (II) VIVANTE(0): test Initializing EXA
[ 161.394] (EE) VIVANTE(0): internal error: GPU Ctx Init Failed
[ 161.394] (EE) VIVANTE(0): internal error: initExaLayer failed in VivScreenInit()
[ 161.394] (==) VIVANTE(0): Backing store disabled
[ 161.404] (==) VIVANTE(0): DPMS enabled
[ 161.874] [drm] failed to load kernel module "vivante"
[ 161.874] (EE) VIVANTE(0): [dri] DRIScreenInit failed. Disabling DRI.
Unfortunately I cannot find solution or reason of the problem.
