Ubuntu lucid blank screen on boot

[fernandoch]

Well, when booting my system, I get sometimes a blank screen. I searched around and couldn't find a proper solution. Can someone give me a hand with that? I have an ATI card

ATI Technologies Inc RV535 [Radeon X1650 Series]

The only option I have is to reset the PC and hope for it to boot without the blank screen...

No one has this problem?

Well, actually I HAVE got this problem, but no solution for it so far. In fact I was looking for one right now, but I didn't find any. I've also got an ATI card, X1950 Pro, running Kubuntu Lucid and KDE 4.4.3. It doesn't happen on every boot, but pretty often the last few days so it would be nice if anybody could help out 8-[
