I'm happy to do it in any package postinst, I was thinking more to keep it somehwere under the desktop team control, as it's something we should care about, while I prefer to have it fixed at least to anyone who has installed ubuntu-desktop.
But I agree it's wrong also for other people using desktop under X11 (and who might have just tried unity in the past), so staying lower is fine. If mesa is fine to accept this, I'm happy to do it. -- 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: In Progress Status in mesa source package in Artful: New Status in nux source package in Artful: In Progress Status in mesa source package in Bionic: New Status in nux source package in Bionic: In Progress 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.
