[Bug 1535058] Re: applications close instantly when launched from the launcher or dash

[fcole90]

I have the same problem, when I launch an app it immediately closes. I
don't think it to be related, but this is happening since I added the
budgie desktop ppa and installed the related packages. Also, can someone
tell me how to launch apps from vt in Mir? Using ual always fails..

Bug description:

  applications close instantly when launched from the launcher or dash
  but... if i launch the apps from a VT (for ex firefox using Xmir or gedit native --), the app loads ok.

  what close instantly means.. it opens the window and then it closes
  instantly in ~0.3s

  -----------------------------------

  This has been traced to two causes:
  pam was not installed, it is now a dependency of ubuntu-app-launch or can be installed directly
  $ sudo apt-get install libpam-cgfs

  and cgmanager is not enabled by default on systems that were upgraded
  and not clean installs. To enable it

  $ sudo systemctl enable cgmanager
