I've got an AMD Radeon R9 270X that works very well with the open-source Radeon driver.
However, I am going to occasionally be using an OpenCL application that requires the proprietary Catalyst drivers to function correctly. Is there a way to install the Catalyst drivers yet only use them when I explicitly choose?
Can this be done with a separate Grub menu entry, and if so, how?
