Public bug reported: I believe this is a different bug than bug 1627311
using a fresh zesty install, logging into unity8 deb session I installed libertine manager Since FF is installed as part of the original image - it shows up automagically in the app drawer. Clicking on the icon, a unity8 app window with a splash appears, but eventually fails. The only real error i see is in ~/.cache/upstart/application-legacy-firefox-blah.log Error: GDK_BACKEND does not match available displays ** Affects: canonical-devices-system-image Importance: Undecided Status: New ** Affects: upstart-app-launch (Ubuntu) Importance: Undecided Status: New ** Also affects: canonical-devices-system-image Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1660450 Title: Firefox crashes unity8 zesty To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1660450/+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
