Comment 2 for bug 99863

i have the same problem upon fresh installation on my notebook (config below).
i need to upgrade with apt-get upgrade, then it works.
but later i upgrade again to kernel 2.6.16 (suggested upgrade!!), the same problem happened again.
good thing is the boot image of 2.6.15 is still on GRUB and i can choose to boot with this version. gnome works fine on 2.6.15.

notebook config:
compaq presario r3000, P4 2.4GHz, 440MB RAM
