Idle timeout does not deal with simultanious logins

Bug #73321 reported by Onno Benschop on 2006-11-26
Affects Status Importance Assigned to Milestone
gnome-power-manager (Ubuntu)

Bug Description

Binary package hint: gnome-power-manager

If two users are logged in (on a laptop), then the idle timeout from the non-active user will affect the power use of the active user.

The way this manifests itself is that the screen brightness dims while the machine is in use.

Changing the brightness back and continuing to work will keep the brightness at the expected level.

Steps to reproduce this problem:
  1. Login as user 1.
  2. Login as user 2.
  3. Switch back to user 1.
  4. Continue to work.
  5. After the idle time-out for user 2 has been reached the screen dims.
  6. Set the brightness to full as user 1.
  7. Continue to work.

That bug shows this as a duplicate:

I know, this is known broken. When more distros start shipping PolicyKit (and maybe another project that Jon is working on) then this will be fixed properly (i.e. managed), but I'm not sure there is anyway we can bodge this on g-p-m's side. I think ubuntu use check-forground-console or something. That might be worth looking into as a temp fix.

I have also noticed that this effect also happens if you have two window managers running on two screens. One screen will time-out, stealing the keyboard/mouse focus, even while there is activity on the second screen - with the same user.

I suppose it's in effect the same situation, that is, two window mangers running - though in the reported form both are on the same screen with different users, what I'm adding is that it also happens with different screens with the same user.

BTW, flicking the mouse across the timed-out screen solves the problem - but you still need to focus back to the window you were working on.

This comment was added just to document a different scenario with the same problem. No further action is required.

Hello, we haven't heard about this bug in some time, and policy-kit in now standard in Debian/Ubuntu. Has this bug been fixed or resolved? Thanks. (setting to incomplete so I know to check up on this, if it still exists, set back to "triaged")

Thank you for taking the time to report this bug and helping to make Ubuntu better. My apologies as I should not have marked this Invalid. The issue that you reported is one that should be reproducible with the live environment of the Desktop CD of the development release - Maverick Meerkat. It would help us greatly if you could test with it so we can work on getting it fixed in the next release of Ubuntu. You can find out more about the development release at . Thanks again and we appreciate your help.

Thank you for reporting this bug. This bug is confirmed in Maverick Meerkat. My User 1 is the first profile created when installing Maverick native. In User 1 primary click System -> Preferences -> Power Management -> one may place the screen brightness as far down as possible. Then I created a User 2, locked screen of User 1, switched to User 2, default brightness was 100%, locked screen of User 2, went back to User 1, screen is at full brightness and cannot be changed despite User 1 prior preferences.
