Successfully got a GUI logon prompt and was able to log in to the desktop. -- 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/1826025 Title: gnome-shell trap int3 no desktop ("Impossible to lock surface front buffer: Function not implemented" on Matrox graphics card) To manage notifications about this bug go to: https://bugs.launchpad.net/mutter/+bug/1826025/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
