Hi MitchThank you for this excellently written Bug report. I have opened a Bug on launchpad.net for this issue, with my initial thoughts being that the Ubiquity installer team will want to know about this. https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1394856 I shall look to triage in due course, as I have a Samsung with an Nvidia GPU For other bugs and issues, you can also report them to bugs.launchpad.net and I would encourage you to open a launchpad account. This will enable you to comment and add detail to the above Bug too.
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.
Finally you can also get hold of us on IRC in #kubuntu or #kubuntu-devel
I will try that as well. - Mitch Golden
