[Bug 764443] [NEW] compiz segmentation fault if xinerama + dual screen


You have been subscribed to a public bug:

I have an nvidia card (01:00.0 VGA compatible controller: nVidia
Corporation GT218 [GeForce 210] (rev a2)) with dual monitor and the
default installation for Ubuntu 11.04.

Description:	Ubuntu Natty (development branch)
Release:	11.04

I wanted to activate xinerama to be able to move applications from one
screen to the other.

1) I open the 'Nvidia X Server Settings' I configure both screens and activate Xinerama, (saving the configuration file )
2) Log out and log in: Gnome will hang up while loading the session. 

If I disable xinerama everything loads fine

I found this error in the syslog
kernel: [ 1670.370995] compiz[3865]: segfault at 58 ip 00007fde90fa26b1 sp 00007fff9bcdb6d8 error 4 in libnvidia-glcore.so.270.41.03[7fde90010000+144e000]
