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> glxinfo | grep "OpenGL renderer string"
OpenGL renderer string: Gallium 0.4 on AMD KAVERI

towo:lenovo-nb> xrandr --listproviders

Provider 1: id: 0x4f cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 0 outputs: 0 associated providers: 1 name:radeon

both devices are listed.

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/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.

Please attach the Xorg log file and the output of dmesg.
Comment 2 Adrian Gabor 2015-04-14 12:29:35 UTC 
Radeon dual graphics doesn't work with DRI2 regardless of compositor.

Please try DRI3. I have an HAINAN dGPU as well and it works flawless with DRI3.
Comment 3 towo 2015-04-14 12:54:45 UTC 
At the moment i use radeon ddx from git (older snapshot) with dri3.
Most apps work, but for example

DRI_PRIME=1 kodi

let freeze the whole xserver and let a zombie process left for /usr/bin/X.

Working over ssh still working. But reboot or halt is not possible, only hard switch off.

I will try to use a new git snapshot and will tell, what's going on with it.
