The issue there is a that nux-tools has a conffile that does
" /usr/lib/nux/unity_support_test || export LIBGL_ALWAYS_SOFTWARE=1"
When the package is removed but not purged the command fails and
software rendering is enabled wrongly
Marco could you have a look, we should probably fix the script to not
export the env if the helper is missing

Title:
leftover conffile forces GNOME is software rendering
Status in nux package in Ubuntu:
Confirmed
Bug description:
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'
