/var/log/Xorg.0.log ought to show what's happening.  Or 0 ... to 9.

'the driver from nvidia'?  Which one? but perhaps you want to run nouveau?

--------------------

I am running the 'nouveau' driver that comes with Fedora 17.

I was commenting that the driver from nVidia, either from their site, or from the rpmfusion site are worse. I know others report that those drivers work better for them, but in my case the nouveau driver has worked better until this recent issue.

I'll get back to you on the log files, I need to regenerate the cases with the projector attached.
