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. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/1768610 Title: leftover conffile forces GNOME is software rendering Status in mesa package in Ubuntu: New Status in nux package in Ubuntu: Fix Released Status in mesa source package in Xenial: New Status in nux source package in Xenial: Fix Committed Status in mesa source package in Artful: New Status in nux source package in Artful: Fix Committed Status in mesa source package in Bionic: New Status in nux source package in Bionic: Fix Committed Bug description: [ Impact ] GNOME shell and other 3D programs run using software rendering after unity removal.

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.
