So you're running Scientific Linux 7. Cool, that's what I was guessing.

Wait a moment here. Did you do something like htis:

* yum install epel-release
* yum install dkms

Or did you get that RPM for dkms from somewhere else than EPEL? Please, be
aware that installing RPM's from random other repositories can be... well,
a source of confusion.


Then I've accessed a Nvidia visual app installed but did nothing there.

Umm. Maybe. You have a working shell hitting Ctrl-Alt-F2? Then it's just X
that is dead, not the operating system. *Good*. Repairing X should be
easier than fixing the boot system.
