Steps to reproduce

  1. Install Dietpi
  2. Install X11 (XFCE)

Expected behaviour

  • Automatic boot via lightdm in to x11

Actual behaviour

  • Console Login and no X11

Extra details

  • I discovered that lightdm has an error “Error getting user list from org.freedesktop.Accounts: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.Accounts was not provided by any .service files” so i installed the package “accountsservice” and this error was gone but still no x11.
  • Then i discovered that it is not possible to “startx”. There was an error (can’t remember exactly what) that it can not connect to dbus. So i installed the package “dbus-x11”.
  • Now i can run “startx” and X11 is starting, but it does not start automatically
  • I also discovered that if “dtoverlay=vc4-kms-v3d” is set in “config.txt” the 7” Display only shows white stripes and no picture (also no cli login screen)
  • Unfortunately, I don’t know how to investigate this further.
  • And somehow I seem to remember that we’ve had this problem before, but I can’t remember the solution.
