Would be great to figure out what all you updated, and what introduced
the regression. I believe package managers tend to keep logs of
things, not sure if the Ubuntu one does or where to find those logs.
I'm sure the internet knows though.

Based on the information easily found online it actually doesn't
appear to be optimus. But it can be hard to tell.

We live in the future. Emails can be large now. Attach them, or
include them inline... either way. Just for giggles, also include
lspci -nn output.

Again, we live in the future. Apparently someone decided that everyone
loves special effects, and can't live without them, so they are often
turned on by default. [Much as they decided that the only use-case for
laptops is watching movies and so you can only get WS LCD's now, and
that brightness == quality, so you have to wear sunglasses when
looking at any modern displays, but I digress.] As I try to stay away
from ubuntu & co, I don't really know what the defaults are these
days. But if it includes gnome-shell, that definitely likes to use GL.
Not sure if you can tell it not to...
