no screen at all??
we have been happily using ubuntu 8.04 for a while on an inherited computer,(aging)which was fine, I bought a new lcd screen for it and configured the resolution and it worked fine for a couple of days. using nvidia driver. Then one day, no screen. I have tested the screen and cable, they work fine, and I hear the drum beats as ubuntu gets to sign in page, so i assume thats working, but all we see is the "no signal" box on the screen.
I guess that the video card could be cactus and will probably change it if no one has a better idea,(i dont have a spare so i'll avoid changing it until after this post)
so to get to the point... is there any common or otherwise, problem that can cause linux to not deliver a signal, and how would i solve it without a screen to read?. I know it's unlikely to be software, but would like some knowlageable input because I am not linux savvy but really like the concept and want to use it more.
cheers in advance
