Created attachment 130753 [details] 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
I also tried DRI_PRIME=1 glxgears It doesn't freeze, but shows nothing.
I recently installed ubuntu 18.04. I also added the PPA ppa:oibaf/graphics-drivers to have the latest version of the driver. Now, when I try DRI_PRIME=1 glxgears it usually works fine, but sometimes the system freezes when I maximize the window. The other software I mentioned, i.e. "Visual Molecular Dynamics", crashes much more frequently, maybe because its 3D job is heavier.
