Timo, indeed I enable several repositories : backports and proposed updates among them. I like to have a system with as recent softwares as possible (at home I use debian testing) and see if everything is ok, report bugs when needed (like "now" ;) for this one. I'm usually quite impressed by the work done on [almost-]bleeding edge packages since this is one of the rare case I found a bug as impacting as this one.
As for mesa, there wasn't any presence of an upgrade. Here is the full list of upgraded packages on that day (the problem appeared at reboot after that upgrade) : $ pwd /var/log/apt $ zgrep -C 5 "2019-05-09" history.log.1.gz | grep Upgrade > ~/may-libdrm-upgrade.log (see attachment -- there wasn't any package removal that day) Apart from libdrm, there was a libreoffice, ffx and cups upgrade but I doubt these could be the cause of the Xorg effects problem I have now. ** Attachment added: "may-libdrm-upgrade.log" https://bugs.launchpad.net/ubuntu/+source/libdrm/+bug/1829872/+attachment/5268874/+files/may-libdrm-upgrade.log -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to libdrm in Ubuntu. https://bugs.launchpad.net/bugs/1829872 Title: No more desktop effects since libdrm upgrade in Bionic Status in libdrm package in Ubuntu: Incomplete Bug description: Hello. I upgraded my system on 2019-05-09 and since then desktop effects do not work anymore. It installed a new libdrm stack : $ grep -A 3 "2019-05-09 *08:53:53" /var/log/apt/history.log | tail -n 1 | awk -F "," '{for(i=1;i<=NF;i++){print $i}}' | grep -A1 libdrm libdrm-nouveau2:amd64 (2.4.95-1~18.04.1 2.4.97-1ubuntu1~18.04.1) -- libdrm-amdgpu1:amd64 (2.4.95-1~18.04.1 2.4.97-1ubuntu1~18.04.1) -- libdrm2:amd64 (2.4.95-1~18.04.1 2.4.97-1ubuntu1~18.04.1) -- libdrm-intel1:amd64 (2.4.95-1~18.04.1 2.4.97-1ubuntu1~18.04.1) -- libdrm-radeon1:amd64 (2.4.95-1~18.04.1 2.4.97-1ubuntu1~18.04.1) -- libdrm-common:amd64 (2.4.95-1~18.04.1 2.4.97-1ubuntu1~18.04.1) I have an ATI Radeon that was working fine with KDE until then. I waited to see if someone had realized it before creating a bug report... It really is annoying : no more transparency, no more auto-hide of windows : my workflow is strongly impacted.
