This is so true. I still think opensuse is great but it didn't work out for me AT ALL. almost anything I tried to do faced with issues.

Ok I did it! opencl works and computer has gui. nice and updated

To be fair, I had this happen to me once with Nvidia's open drivers and I switched back to the default... but just once, and either way if you do it properly and you won't have to worry about this stuff. It was an easy fix to switch back that took all of five minutes away from me—and that's if you count the boot time. You shouldn't.
