When engaged, Xfwm4 GL compositor with XPresent VSync
$ XFWM4_USE_PRESENT=1 xfwm4
xrandr related problemos(--off/--auto/--rotate) start with this particular
commita
"enable dri3 support without glamor"
<a href="http://cgit.freedesktop.org/nouveau/xf86-video-nouveau/commit/?id=241e728">http://cgit.freedesktop.org/nouveau/xf86-video-nouveau/commit/?id=241e728</a>
With the former commita, which works OK
<a href="http://cgit.freedesktop.org/nouveau/xf86-video-nouveau/commit/?id=762b22f">http://cgit.freedesktop.org/nouveau/xf86-video-nouveau/commit/?id=762b22f</a>
while "xrandr-ing", there is no warning in the kernel ring buffer, whatsoever.
Still, SEGV catches xfdesktop.
Yet with commita 762b22f, while S3 RESUME, warnings are still occurring,
very persistent, aye. :)
In contrast, when engaged, Xfwm4 GL compositor with default VSync,
xrandr related problemos(--off/--auto/--rotate) are "all the way",
at least I have tested from xf86-video-nouveau-1.0.3 up to the latest,
xf86-video-nouveau-1.0.12.
So there is no love there at all.
I wonder whether this problemo is comparable to one occurs with the
clutter/mutter/gnome-shell
