I seems the bug returned in March. After not rebooting my laptop for 10 days, unity doesn't start and the same segfault in libcompizconfig.
My original bug-report: 1741447 https://askubuntu.com/questions/992571/gui-unity-crashing-in-16-04-lts-after-updates-2018-01-04-compiz-segfaults See Workaround 3 on the askubuntu page. For me returning to low graphics mode seems the best workaround for now. It works fine now, so the bug has mutated a bit -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/1735594 Title: [regression] compiz crashes after Mesa upgrade To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/1735594/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
