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-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
