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 Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1829872 Title: No more desktop effects since libdrm upgrade in Bionic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libdrm/+bug/1829872/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
