Without that additional information it is near impossible to find a working solution. Anyway, you can roll back by selecting the previous kernel at the boot menu and then uninstall the not working kernel. Thank you a lot for the information and help. I have added it to <A href="https://help.ubuntu.com/community/UpgradeKernel">https://help.ubuntu.com/community/UpgradeKernel</A> I have some doubts (perhaps I am going to personally experience, but better if I am ready then): how to uninstall the new (not-working) kernel after booting ?. I don´t know if I can use synaptic for this or directly delete a partition /files ? (which). If the new kernel works OK (after testing it: screen, GUI, sound, Internet and networking - PPP and WiFi-) , I would uninstall the old one (to save space in the hard disk). I image the uninstallation of the old kernel is similar to the uninstallation of the new kernel. I can add the answers to these questions to the cited help page. Finally, an idea: ubuntu-installer could control this upgrade / roll-back process, as an additional help tool for the final user, to make it easier (in a similar way to the use of update-manager to upgrade the kernel).
