Created attachment 121146 dmesg output
My laptop has the following discrete graphics card (lspci output):
0a:00.0 Display controller: Advanced Micro Devices, Inc. [AMD/ATI] Sun LE [Radeon HD 8550M / R5 M230] (rev ff)
When running glxgears (or any graphical application) with DRI_PRIME=1, the window appears but it stays just black (also it does not print any FPS in the console).
After starting glxgears the first time, the GPU locks up (see dmesg.txt).
