[Bug 892878] [NEW] Xorg freezes for up to 30 seconds after screen mode changes

 

Public bug reported:

Using the 285.05.09-0ubuntu1 NVidia drivers on my Precise install, any
change in screen mode using:

* NVidia settings - ie. enabling/disabling a second screen in Twinview;
* Starting a movie in VLC Media Player;
* Unplugging and/or plugging in a laptop mains lead;

will result in the system becoming unresponsive for up to 30 seconds as
it changes screen mode. This problem does not occur with the previous
NVidia drivers (280.13-0ubuntu6) which is the workaround I am having to
implement to avoid this bug at the moment.
