Blank screen at boot.
I have a curious one here. I have just installed Ubuntu on a machine that has an ATI Radeon 3450 video card installed.
If I boot the machine into recovery mode and then select 'normal boot' at the pause I get to a fully functional desktop that is using the fglrx driver. Compiz is happy and my graphics look great.
If I boot normally and just let the machine do its own thing I get just past the 'select' screen and the machine stops. There is no further disk activity and the monitor goes into standby mode.
I can't see anything relevant in any of the log files.
Does anyone have any ideas 'cos I've run out of ideas!
