Must be nouveau as none of the major distros ship the nvidia binary

Will reveal the truth. The only way it can't be one of the two is if
it's Wayland and Wayland doesn't use nouveau (which I have zero
knowledge about either way (purposely)).
Well, duh, why didn't I think of using lsmod. Thanks! Definitely
nouveau is running:
# lsmod | grep -P 'nouveau|nvidia'
nouveau 1662531 8
video 24538 1 nouveau
mxm_wmi 13021 1 nouveau
i2c_algo_bit 13413 1 nouveau

Not sure why it's so non-verbose as far as logging, though, and
whether that can be controlled.
says "(II) glamor: OpenGL accelerated X.org driver based." That
Oh, forget what I just said about Wayland.
Glamor should sit on top of nouveau. Nouveau does a decent amount of
hw acceleration now too, it's just the super-modern fancy stuff it
won't do (like vdpau last I checked). If you want super low-CPU
accelerated video, vdpau is awesome.
Yeah, no, Wayland is a whole other world I have yet to begin
exploring, and I may delay the journey for as long as I can. As for
vdpau, given the lack of feedback in the X logs, I can't tell if
it's there or not. It's not showing up in lsmod, if it's supposed to
appear there. Anyway, not too worked up about performance for this
application.
gain voltage resolution on the Y.) The trick is once you have the
display configured properly for your login account, you need to copy
that to GDM's configuration:
I'm using lightdm, but it probably has a similar setup, I'll check it
out, thanks! I figured it was a matter of the dm being too early in
the sequence to know what the user has selected (part of the problem
of randr being configured per-user rather than per-system like the
good ol' xorg.conf days). Since I only reboot once every few months
(whenever a CVE pops up that actually applies to me), it's not high on
my priority list. :-)
cp /home/<username>/.config/monitors.xml
/var/lib/lightdm/.config/
is supposed to do the trick based on what I read
(https://askubuntu.com/questions/408302/rotated-monitor-login-screen-needs-rotation).
The xrandr hacks appear to be deprecated.
