Yesterday I spent some time and many reboots trying to troubleshoot this
problem.  No success.

I cannot find out how to make Fedora 18 go into "Interactive Boot" that
used to happen when you pressed the "i" on boot.  I just crashed my
system trying to do that.

Any pointers on getting an interactive boot screen?

The screen boots to fast to see the changes.  I tried to video the boot
sequence and I do know that the screen changes before the boot sequence
displays "Fedora 18 (Spherical Cow)".

The problem happens before

I did find one conflict with xorg-vesa-drv and nouveau but I removed
xorg-vesa-drv and the problem is still there.

I am almost at a point of doing a re-install but with F19 is just around
the corner and hopefully a clean install that will fix the problem.

Not worth the time to work in this anymore.

Robin
