'a' at the prompt after writing the report, but it was included by the

llvmpipe is software rendering, not hardware acceleration.

Looks like something is preventing the radeon kernel driver from
loading / initializing. Is it built into the kernel or as a module? If
the latter, what happens if you try to run 'sudo modprobe radeon' from
