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
*smacks forehead* it's the DRI false, right? I've commented out that
file and rebooted and I see the intel card being used now.

Can I somehow reset the xorg conf (and expect it to work)?

If you want to try that, you can grab a more recent kernel from
http://kernel.ubuntu.com/~kernel-ppa/mainline/ but I doubt that this
will fix your issue. I'd bet on a configuration thing, but not sure
what. You don't, by any chance, have a custom xorg.conf (in /etc/X11
or /usr/share/X11)? I
I see BTW that intel recommends kernel 4.16 in its stack
(https://01.org/linuxgraphics/downloads/2018q1-intel-graphics-stack-
recipe). Could that be an issue? I have 4.15, I don't think a newer
kernel is available in Ubuntu.

I look a quick look at your posted data. It does seem odd that your
system starts out configuring the drm and then uses fb. Do you have
anything custom on your boot line, like some video parameters? E.g.
'cat /proc/cmdline'. More grabbing at straws.

Well, this sounds like a different problem. The problem I reported was
very clearly the result of an incomplete package upgrade/removal
resulting in a failed test for unity compatibility leading to setting
that environment variable for software gl.
You might consider opening an new bug report
grep -H LIBGL /etc/X11/Xsession.d/*
same results (being none)

Emiliano: I'm grabbing at straws, but try checking for other files in

LIBGL_ALWAYS_SOFTWARE=1' in the environment. E.g. 'grep -H LIBGL

I'm not an expert, but you might want to see if you can gain some
insight from the output of 'journalctl -b0'.
E.g. is your system using the framebuffer driver "fbcon: xxx" or "[drm]
..." during boot up?
In the 'journalctl -b0' output I posted above,you can see that it's
using the frame buffer.
That file was gone before the reboot, verified.

I've purged nux-tools but the problem is still there for me.

I have figured out the problem: the installer removed nux-tools, left
over from unity, but did not purge it. This left a start up script in
/etc/X11/Xsession.d which interfered with gnome. Purged that and the
problem was gone.
So this is a dependency bug in the nux-tools package (or perhaps
