I tried different kernels, at the moment I'm using 4.6.4 (the latest of the 4.6 series)
In MATE Tweak/Windows only "Marco (no comp)" and "Marco (Software compositor" are available.
In Synaptics Package Manager "compiz" is marked as installed, as is OpenGL.
I marked them for re-installation with all related components and applied the changes.
Also I installed "CompizConfig Settings Manager" using the "Ubuntu Software Center" as it was not installed.
System Information indicates "Software Rasterizer" for "OpenGL Renderer".
R7 270X GPU (I do have a Sapphire 7970 available too)
Ubuntu 16.04.1 LTS up-to-date
Kernels 4.1.30, 4.6.4, 4.6.2, 4.4.4, 4.5.0, 4.4.3-jm
The Kernel modules are also installed correctly.
What could be wrong or what am I doing wrong?
You're using an unsupported graphics card. Compiz uses 3D acceleration, and at the moment the radeonsi driver (needed for both your cards) doesn't run correctly on Big-endian systems. We have someone working on it, but these things take time.
It is possible to run the X1000 with 2 different graphics cards in, one for 3D on OS4, and one for Linux, but it would take some setting up. and I don't think I have the time to test that out right now. (OS4 is much nicer to get working with 2 cards in my experience)
Edit: I also tried to install the unofficial Mesa lib 10.4 (from page 22 in this thread)
That only fixes texture formats in the r600 driver, it doesn't contain a radeonsi driver sorry.
When we get 3D on HD7xxx R7/R9 cards in Linux you will hear about it.
