Description Scott Spurrier 2010-07-21 00:33:36 UTC

Description of problem:
This problem was reported on RHEL 6 beta snapshots 6 and 7.

On a system with dual monitors using nvidia twinview, the gdm greeter screen will randomly switch screens before login.  It appears this is a timing problem related to how quickly the monitors sync up when X is started.

The primary display should be consistent regardless of how long the monitors take to sync up (within a reasonable timeout).

This is switching at run time...each log out, it can potentially switch screens depending on the sync speed of the monitors. I have multiple sources on my monitors, so when X restarts it can cause the monitors to search for signal.

versions...
metacity-2.28.0-15.el6.x86_64
gdm-2.30.2-3.el6.x86_64
