Problemi con gnome 2.6

["Sok" <socamela@katamail.com>]

Quando avvio gnome 2.6 ricevo:

X server version data:
The XFree86 Project, Inc
40300001
You are using XFree 4.3.0.
There are known problems with complex XKB configurations.
Try using simpler configuration or taking more fresh version of XFree
software.
If you report this situation as a bug, please include:
- The result of xprop -root | grep XKB
- The result of gconftool-2 -R /desktop/gnome/peripherals/keyboard/xkb

come posso risolvere?
uso sarge con kernel 2.4.26
