lsmod | grep -P 'nouveau|nvidia'
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)).</pre>

Well, duh, why didn't I think of using lsmod. Thanks! Definitely
nouveau is running:<br>

Not sure why it's so non-verbose as far as logging, though, and
whether that can be controlled.<br>

<pre wrap="">
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.</pre>

<br>
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.<br>

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. :-)
