[Bug 994755] Re: malformed autostart .desktop file prevents session opening

[Fabio Marconi]

Hello
If the system is set by Admin to start an application, it *has* to start it, because if the application is something security related or essential for the workflow, then is better not to proceed at all.
A valid option can be a popup alert informing that the system is stopped cause a problem in a startup file, but in every case the system needs to be stopped.
Assigned to upstart to evaluate.
Thanks
Fabio

Title:
  malformed autostart .desktop file prevents session opening

Status in “upstart” package in Ubuntu:
  New

Bug description:
  1) Ubuntu release : 12.04 LTS 64 bits

  2) Application : startup procedure (package unknown )

  3) What should happen :

  When a .desktop file used in autostart (located in /etc/xdg/autostart/
  or ~./config/autostart/) is corrupt, it should be skipped and session
  startup should continue.

  4) What happens :
  Session does not start (freeze).
  Impossible to open ANY session from session manager (lightDM).

  5) Détails :

  I altered one of the .desktop file located in /etc/xdg/autostart/ in
  the purpose of having it start only in certain environment.

  I edited the desktop file, adding two lines :

  OnlyShowIn=Unity;GNOME;
  AutostartCondition=GNOME if-session gnome-fallback

  Note the error on the second line it should be (?)
  AutostartCondition=GNOME3 if-session gnome-fallback

  After that no session did open. I had to remove the .desktop file from
  another OS.

  6) How to reproduce :

  Test case included for clipit application, to be copied in /etc/xdg/autostart with correct permissions.
  Clipit should have been installed and launched once, before replacing its startup file with the one included, in order to reproduce the same conditions.

  WARNING : make sure you can delete the file accessing it from another
  OS as you will not be able to start a session. (Or have another way to
  bypass the session startup)
