Hello,
How could explain this behavior and investigate it. On the same machine, I have 2 fedora 13 installations with the same kernel and the same package upgrade, but not the same installed packages. On one system, there is not problem to switch from the graphic to the text mode by using Ctl+Atl Fn, on the other one when I try to switch I never get the text mode right, ie. I do not get the login banner. The loading are exactly the same (ie. the grub command line).
This behavior does not depend on the user: ie. root or not.
Thank.
