Had a couple of problems though, but not serious once I figured out the causes:
My main system failed to boot completely, removing P96refresh from my startup cured this. Is P96refresh obsolete?
Tested a more basic setup to figure out what was causing the first problem, it booted fine but none of the disk icons could be clicked on. Then I realized that the display had been squashed and clicking in the black area to the left of the icons worked. This was in full window mode with a display smaller than my actual resolution. Switching to window mode worked as usual.
