Thank you very much Sir

  I'd been setting this line below the Display sub-section:

  Virtual 1024 768

  Nothing more or less.

  I made an 'ls -l /etc/X11/xorg.conf', which gives:

  rw-r--r--             xorg.conf

  Tried to set: 'chmod 777 /etc/X11/xorg.conf'  No success.


  I made a diff of Xorg.0.log after startx from root then normal user,
it gives this:

-----------------------------------------------------------------

  Meanwhile, there is a line in this Xorg.0.log , which indicates it
finds a checksum error in the V_Bios. I presume this is the video card
Bios, if this is the case, maybe the bios of my card is corrupt ?

  After all, I believe this is not an X problem, but more probably a
display manager problem.

  The only concerned part of the screen, is the display manager, with
its menus an menubars.

  When I installed this FC4, I didn't enter the horiz/vert sync refresh
of my monitor, for I didn't have those.

  Might it be, the gnome configuration has been set up accordingly to
support only the 800x600 and 640x480 resolutions, the system found
available at the install time ?

  This way, the problem seems for me to be able to reconfigurate the
gnome display manager, so that it might support higher resolutions.

  Thank you very much for your help.

  Best regards.
