As some have read on the Soapbox I had a problem with the first install of 15.04 and thought a second install fixed it.
Yes most things worked fine until I changed from Nouveau to nVidia 346.
A few minutes after logging in the created hot keys failed to work and shutting down is an exercise in patience.
The first few minutes I can use the hot keys and then it's over.
I went back to Nouveau and the hot keys and shut down are normal again...
It does not fix the problems with Dolphin like forgetting an added network drive and the issues with the root actions service.
