I just remembered that I attempted to delete a package from my system and it started to erase things, but I stopped it. This may have done the damage. It had also erased the Repetier host package that I used to generate the Gcodes for my K8200 printer. I reinstalled Repetier host and that works, but pycam still does not. Nothing else seems to be affected. However if the Kernel is the location, is the radeon package in a separate file? If it is, what could I reinstall to recover that driver?
