dmesg output

My laptop has hybrid graphics.

Output of "lspci | grep AMD":

"0a:00.0 Display controller: Advanced Micro Devices, Inc. [AMD/ATI] Sun LE [Radeon HD 8550M / R5 M230] (rev ff)"

I use an application called "Visual Molecular Dynamics", which opens an OpenGL window and renders 3D images. There is no problem when using the integrated GPU. But when I run the application using DRI_PRIME=1, the system freezes when the OpenGL window is being opened. I need to use the dedicated GPU, because the integrated GPU isn't powerful enough for my work.

OS: Ubuntu 16.04 64bit, with last updates
