Introduction

Bugs relating to screen locking issues typically fall into 4 categories:

  1. Screensaver failing to start after the inactivity period times out
  2. Screensaver failing to start when triggered manually
  3. No password prompt after resuming from suspend/hibernation
  4. Screensaver not hiding desktop and applications properly

How to file

Screen locking is a complex combination of many different packages, applications, and tools. For detailed information on how screen locking works, see DebuggingScreenLocking/HowScreenLockingWorks.

Important information

  • What desktop environment does this problem occur in? (GNOME, XFCE, KDE, etc.)
  • Do you use visual effects? (System/Preferences/Appearance/Visual Effects)
  • Is this a laptop or a desktop machine?
  • How many monitors do you use?
  • If it is a laptop, do you use an external screen?

Getting GConf values

The following command will dump all the screen-locking relevant settings that are stored in GConf:

$ gconftool-2 --dump /apps/gnome-screensaver /desktop/gnome/session /desktop/gnome/lockdown > screen-locking-debug.xml

How to Forward

In the event that the package or subsystem has an upstream bug tracker this section should contain detailed steps to forward a bug to that tracker. Some packages may just link to the general "How to Forward" page for another bug tracker like Gnome's bugzilla or freedesktop.org's bug tracker.
