glxgears/es2gears on X11 and Ubuntu 12.04/armel show only black rectangle

Hi,

 

my current rootfs setup on an iMX6Q is

- Ubuntu 12.04 armel (without Unity)

- imx_3.0.35_4.0.0 kernel

- Xorg server 1.11.4

- gpu-viv-bin-mx6q-3.0.35-4.0.0.bin

- xserver-xorg-video-imx-viv-3.0.35-4.0.0.tar.gz

 

I have the Xorg server running without any window manager and when I start the glxgears or the es2gears example app I see just a black rectangle.

Only starting the glxgears with the -fullscreen argument shows the glxgears in a small rectangle on the left bottom of the screen. (so no fullscreen at all ...)

 

It seems that my problem here is similar to that two posts!?!

Black rendering of windowed Open GLES applications on iMX6 Vivante under X11

 

With the Freescale Ubuntu Oneiric 4.0.0 rootfs the glxgears and es2gears example app works. One difference is that I does not use Unity on my 12.04 precise rootfs.

 

Any hints to solve this issue are welcome.

 

Cheers
