You cannot do compositing or XRandR and Xinerama at the same time. Each of |
| 31 |
those NVidia cards has two outputs. One approach is to only use one of the |
| 32 |
cards and us NVidia's TwinView, which gets around having to use the |
| 33 |
Xinerama extension. Then you can have a single big desktop spanning both |
| 34 |
monitors, and the eye candy of desktop effects. |
