Thanks.  I do have a launchpad account and I regularly do submit bugs to 
it.  My concern is that this bug is sort of a worst-case scenario, as far 
as responsability goes.  The bug by itself is quite serious - but it's not 
clear who fixes it.  It isn't probably a kubuntu packaging issue.  It may 
be a plasma 5 kde (upstream) issue.  It is I guess even more likely to be 
a combination of plasma 5 and nvidia driver issue - in which case I don't 
know where to report it because that driver is proprietary.

The installer actually supplies the open-source nouveau driver.  There is 
no control panel that reports the clock speed under nouveau.  From the 
sound of the fan I am guessing that nouveau is also running the clock at a 
high rate a lot of the time.

At the very least all of this should be looked into by someone who knows 
more about it than it - preferably before the decision to make Kubuntu 
15.04 be plasma 5 is permanently taken.

I will try that as well.
