Comment 1 for bug 164290

I can confirm this with Gutsy and current Hardy. Every time I enable the Nvidia driver with the restricted manager I get a blank screen after restart but system reacts normal and I hear the boot sound.
I have to add the line >>Option "UseDisplayDevice" "DFP-0"<< to the Screen section to activate the LFP. This doesn't happen in Feisty.
