In your package manager be sure that you have the last header: > linux-headers-2.6.31-14 > Then open your menu.lst > *gedit* /*boot*/*grub*/*menu*.*lst* > And add one entry with the last kernel, like this: > title Ubuntu 9.10, kernel 2.6.31-14-generic > uuid xxx > kernel /boot/vmlinuz-2.6.31-14-generic root=UUID=xxx ro i915.modeset=0 quiet splash > initrd /boot/initrd.img-2.6.31-14-generic > quiet > > You can copy your old entry with the old kernel and substitute with this new version of kernel. Instead xxx you have to insert your uuid (the same of the old entry of JJ) PS: Keep, for safe, the old entry too. 2009/11/7 Tomáš
