Okay, thanks for the info.
I assumed it was a new install and you got stuck at that point.
From what you describe, I could think of two possibilities.
1) Your friend is using a video card that makes use of a proprietary binary blob. Cards like ATI, NVidia, Intel, etc, etc, etc, have binary blobs provided by the manufacturers of those cards. Mageia, Mandriva, usually take advantage of those blobs because it provides added eyecandy such as being able to do some added features. It may be possible that your friend got an update, and the blob got replaced with one that doesn't work. If that is the case, your friend should start a bug report, since this is a bug that should be fixed for "everybody" that has that type of card.
2) Your friend is doing stuff as a root super user. Ubuntu went to great lengths to hide "root". In Mageia, it's a bit more easily accessible. If your friend is using root, it is a habit that needs to be reduced, because it's possible to mess stuff up much easier as root. Think of Window with Admin and limited accounts. In Windows it's difficult to have a usable computer as a limited user, so it is understandable if this habit continues into linux, but in linux, a lot more is stuff is workable as a limited normal user. If you use Root, it's a habit you need to reduce so you don't mess yourself up.
If you installed Mageia using the DVD, and it was working okay before, I would recommend using the DVD as a recovery disk. Simply insert the DVD and reboot as if you are going to install. On the question where it asks, fresh install or upgrade, choose upgrade. Make sure you do not wipe and partitions if you get to any such questions since you are not doing a fresh install. This should recover you back to your original point. If you had trouble with graphics, I'd choose another graphics card choice in that menu (Vesa generic).
Once recovered, you should have everything working again. Now, if you do an update, and end up in the same problem, then there is a bug that needs fixing. Something wrong with the update needs fixing.
