Please describe the problem:
When I have a second screen of X (screen :1), not using Xinerama, separate desktop, The screensaver will not notice when I am active on that second screen. It will lock my screen if I am not active on the primary (':0') screen.

It is not a new bug, but I cannot find it at gnome.org, I found it at Ubuntu (launchpad.net) #93466 and redhat #238315.
I myself am using Gentoo, which bugtracker does not have a record. But I am sure this has nothing to do with the distribution I am using.

For information, I am running on a laptop with ATI X1600 card, in multi-head config with the fglrx drivers. none of above bugs reveal a solution

Steps to reproduce:
1. Set up system with multi head (don't know if it is related to fglrx)
2. be active on the second screen



Actual results:
the screensaver kicks in even when active on the second screen (writing mail or giving presentation)

Expected results:
The screensaver should keep reseting the idle timer and not kick in when active on screens other than 0.

Does this happen every time?
This issue is structural

Other information:
I'd be more than happy to provide additional information when needed.
