Gnome panels note displayed

[destroyedlolo]

Binary package hint: xorg

Hi,
Before upgrading my system to 10.4, I tried to boot on the live CD.

Unfortunately, no Gnome panels is displayed. TO be more precise, gray bares are displayed on the top and bottom of the screen (but only 2/3 screen long) but don't containing anything. No mouse action display menu or anything else.

ALT-F1 display usual Gnome menu.

Best regards,

Laurent
