[Bug 1569357] Re: Ubuntu 16.04 - Unity desktop session broken when using non-LightDM as X Display Manager
Megathanks to Nathan Adams for post #14 on this page. My Unity desktop had been functioning perfectly since upgrading to 16.04 nearly 10 months ago, but it suddenly broke yesterday for no reason I can fathom. (Last system action I had performed was to enable the system firewall - ufw.) I tried uninstalling and reinstalling Unity and LightDM, but neither action solved the problem Then I entered each of Nathan's 10 lines above in a terminal, and when the last line executed, Unity sprang back to life.

I am also unhappy to confirm this problem but happy to find that this is a corroborated bug. As the OP reports, "gdm3" hangs the system before the Unity desktop comes up, and trying to use "sddm" starts an X session without any window management. -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to sddm in Ubuntu. https://bugs.launchpad.net/bugs/1569357 Title: Ubuntu 16.04 - Unity desktop session broken when using non-LightDM as X Display Manager To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lxdm/+bug/1569357/+subscriptions -- kubuntu-bugs mailing list kubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs

For the people like me who have trouble finding how to switch to lightdm: sudo dpkg-reconfigure lightdm but also remember to: sudo systemctl enable lightdm.service You also might have to install lightdm before either of these if you didn't have it installed previously: sudo apt install lightdm Afterwards, reboot. -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to sddm in Ubuntu. https://bugs.launchpad.net/bugs/1569357 Title: Ubuntu 16.04 - Unity desktop session broken when using non-LightDM as X Display Manager To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lxdm/+bug/1569357/+subscriptions -- kubuntu-bugs mailing list kubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
