I have a fully updated F22 system also with an nVidia card but I'm running the nVidia driver via rpmfusion. No problems like you describe. GeForce GTX 660 is my card.
Mine's a GT630, nothing special. Ironically, I had switched to Nouveau a month or so ago because I had a problem with the Nvidia driver (system couldn't start X11 for some reason). I switched back and problem solved, so it looks like a Nouveau/Plasma issue.

Well if you update via dnf there is a dnf.log. If you do your updates via the apper systray icon I have no idea where the logs are....and I asked here and got no response.
dnf.log is quite different from the old yum.log. With the latter you had a simple time-sequence of install/update/remove actions. With the latter you have some internal logging data of no interest to the average user. There is a way to get approximately what I wanted ("dnf history info <number>", where <number> comes from a list of transactions produced by "dnf history", i.e. two commands to get more information than I really care about).
