<pre>a have a Lenovo Notebook which contains a FX-7500.
There are 2 graphics devices in:
root@lenovo-nb:/home/towo# lspci | egrep -i "displ|vga"
00:01.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI]
Kaveri [Radeon R6/R7 Graphics]
01:00.0 Display controller: Advanced Micro Devices, Inc. [AMD/ATI] Jet PRO
[Radeon R5 M230] (rev ff)
The system is using the Kaveri graphics.

towo:lenovo-nb> DRI_PRIME=1 glxinfo | grep "renderer string"
OpenGL renderer string: Gallium 0.4 on AMD HAINAN
seems to work correct.
DRI_PRIME=1 glxgears
shows only a black window, but the fps are shown in the terminal, i start from.
towo:lenovo-nb> LIBGL_DEBUG=verbose DRI_PRIME=1 glxgears
libGL: screen 0 does not appear to be DRI3 capable
libGL: pci id for fd 4: 1002:6665, driver radeonsi
libGL: OpenDriver: trying /usr/lib/x86_64-linux-gnu/dri/tls/radeonsi_dri.so
libGL: OpenDriver: trying /usr/lib/x86_64-linux-gnu/dri/radeonsi_dri.so
Running synchronized to the vertical refresh. The framerate should be
approximately the same as the monitor refresh rate.
8793 frames in 5.0 seconds = 1758.569 FPS
doesn't even give any error, but the windows stayes black.
I use xfce 4.12 and have tryed 3 different compositors, with all i get the same
black window. Resizing the windows does not help (that i read in many bug
reports).
kernel is 4.0.0-rc6, xserver is 1.16.4, mesa is 10.6-git and radeon driver is
7.5.0
There are zero errors in the terminal or logfiles.</pre>
