In fact, I have saw this morning on
http://www.cyrius.com/contact/index.html that the best dirver for my
computer should be the ATI Radeon Mobility U1. Thus, now the
/etc/X11/xorg.conf gives
Section "Monitor"
Identifier "Monitor0"
VendorName "Monitor Vendor"
ModelName "LCD Panel 1024x768"
HorizSync 31.5 - 48.5
VertRefresh 40.0 - 70.0
Option "dpms"
EndSection
Section "Device"
Identifier "Videocard0"
Driver "radeon"
VendorName "Videocard vendor"
BoardName "ATI Radeon Mobility U1"
EndSection
Since this driver is given in the Fedora Core 2 video driver list, I
have choose it.
But, again, I have the same pb. described before.

Yes.

When I run the very simple game Chromium given in the Fedora Core 2 DVD, the results are very bad even by choising screen size = 800 x 600 and graphics level = low in the Chromium configuration : the results are so bad that it is impossible to play !!!
Moreover, I can see by using many shell terminals for example that the video has sometimes difficulties that my very old pc does not have ...).

There is no monitor driver on Linux. There are simply frequency and
