[Bug 1768610] Re: leftover conffile forces GNOME is software rendering
Yeah, I basically did the same too, but honestly I didn't want to change
nux again with another SRU (I preferred to fix this with just one on
that side); and most importantly in a such way. As it would now include
some checks that depends on changes done in other packages, making from
my POV things even more hackish and annoy to matain and easy to be
broken.
Not that other solutions wouldn't involve the other package (say mesa)
to act on nux file, but that should be in a way that nux is not aware of
that, creating any kind of "inter-dependency" in between them.

Bug description:
[ Impact ]
GNOME shell and other 3D programs run using software rendering after
unity removal.
This SRU covers only the upgrade case or if nux-tools removal happens
after this update, for people who already upgraded and in broken state
another SRU will follow.
[ Test case ]
· Install xenial
· Upgrade to bionic or artful
(assuming you're using a GNOME session)
· sudo apt remove nux-tools
· log into your session
. From terminal:
- printenv LIBGL_ALWAYS_SOFTWARE
Should print nothing (and return an error)
Same should happen if you don't remove nux-tools but you change
`/usr/lib/nux/unity_support_test` not to run properly (replace with a script exiting 1), but you're running a GNOME session.
· If running Unity session instead, ensure that
printenv LIBGL_ALWAYS_SOFTWARE equals 1 in case that you're running
in an environment with no 3d support (VMs are easy tests)
[ Regression Potential ]
Unity desktops with no 3d support could not start anymore.
===========================
After an upgrade from 17.10 to 18.04, I noticed that all gnome windows
animations were gone. After some digging, it seems that gnome-session
incorrectly assumes that my graphics has no acceleration, when in fact
it does: it's a i5-2520M CPU @ 2.50GHz with Intel integrated graphics
(i915 driver).
I've tried this with and without the xserver-xorg-video-intel package
(a.k.a. Intel driver) with the same behavior.
The output of gnome-session-check-accelerated is: llvmpipe (LLVM 6.0,
256 bits) however the system should have DRM 2.0 capability.
GL checks (e.g. glxinfo, glxgears produce the expected output from a
working DRM system).
mesa-utils and mesa-utils-extra are both installed.
I can't find a work around. Perhaps there is something wrong with my
install/upgrade?
Everything else works fine, although the graphical transitions are no
longer smooth. But it would be nice to restore the expected behavior.
I have attached the log of 'journalctl -b0'
