I got it to work, and it fixes my problem with the launcher resulting in an unknown file error on /usr/bin/compiz.
Go to Software & Updates via command line ubuntu-software & and selecting it from a list of apt applications. Use Developer Options to enable xenial-proposed. Then run command line: sudo apt-get install libgl1-mesa-dri/xenial-proposed This installed it for me. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to 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 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
