Hi Brice, thanks for the fast answer!

Here is the result for all resolutions:

  1400x1050: same resolution as 1600x1050, but with some screen left
             unused left and right. (not perfectly centered).

  1250x1024: the permutation bug happened sometimes, but not always. Ugly display.

  1400x900, 1280x960, 1280x800, 1280x768: Ugly display, no permutation bug.

  1152x768, 1024x768, 800x600, 640x480: Ugly display, permutation bug.


After playing a bit with the resolutions, the background screen became
green and it was impossible to change it using the GNOME system menu.
Whey I tryed to logout, X froze (but not the mouse pointer). In a second
session, this did not happen anymore.

I used the GNOME system menu to change the resolutions.

Have a nice day,
