Hi Paul I have matrox g550 graphics card and it war recognizet automaticly during instalation
i tryed to boot in command line but no error message appears
No error message *should* appear in command-line mode because you're not running X, and it was X that was having problems.
Log in as any user, and run the following command:
$ startx >X.out 2>X.err
This will attempt to start X and will probably fail. However, it should leave some diagnostic messages in the files X.out and X.err that may help to identify the problem.
Paul.
