Status in nux package in Ubuntu:
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
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
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'
