I'm running Kubuntu 15.10 with Blender 2.76 64-bit. PC is a laptop with the ATI Mobility Radeon HD5850 graphics card. (specs: kernel 4.2.0-16-generic, 12GB RAM, 2GB GPU RAM, KDE Plasma 5.4.2)
I can't install the fglrx proprietary driver, otherwise Kubuntu won't boot; I have to use the open-source driver.
My question is: is there a way I can utilize the GPU processing for Blender (using Cycles engine) in Ubuntu (Kubuntu, or any of Ubuntu's flavors) without install the ATI/AMD proprietary driver?
Thanks in advance!
