Fix unlocker_daemon.py for Ubuntu 18.04 and onwards.

Open appositeit opened this issue 5 years ago • 0 comments

From 18.04 Ubuntu changed back to the Gnome desktop, and a bunch of the tooling used in the unlocker-daemon.py broke.

To fix this we need to:

  • Identify the user who's session we want to unlock
  • Get the DBUS_SESSION_BUS_ADDRESS for their dbus.SessionBus()
  • seteuid to their uid

The original script looks for the first 'real' user in /etc/shadow. I look for the first process run by a non-daemon user process with a DBUS_SESSION_BUS_ADDRESS in their environment and use that BUS_ADDRESS and user's uid to seteuid.

The orginal script shells out to control the screensaver, I've modified it to use python dbus commands to query screenlock status and lock/unlock the screensaver. I think it should work with various window managers, but it's only been tested on gnome. Behaviour is undefined if there are several user sessions with window managers running.
