[Wlug] Screen goes blank with ubuntu and geforce 8800 GTS.

[Kieran O'Callaghan]

I have system I just put together with a PCI-Express Geforce 8800 GTS 
running ubuntu 7.04.  During installation of Ubuntu everything showed up 
fine on screen. After installation, I ran into the problem that right 
after grub starts loading linux, the screen goes blank (monitor light 
turns from green to amber) and stays that way right up until X loads, at 
which point I get video.  This hasn't been a problem so far, but I just 
installed some updates and it seems like now X isn't loading or I'm 
getting some sort of message before X loads, because it turns on and 
just stays blank the whole time.
It seems like it would be easy if I just put a different video card into 
the system, but I don't even have another PCI express video card. I also 
don't have any PCI video cards anymore.  All I have are AGP cards and 
the system doesn't have an AGP slot. So, it looks like taking the hard 
drive out and moving it to another system is the only option.
Any thoughts on why the screen is doing that would be appreciated. The 
monitor doesn't seem to be getting no signal, because normally it brings 
up a message saying no signal rather than just blanking. It seems more 
like it's gone into a power saving mode. I've tried it with other 
monitors and had the same results.
