I read somewhere that old versions should be removed as they slow down the booting process.  Though I don't really have any complaint about what seems to me to be a quick bootup anyway.  It's just that I don't like all those lines of information in my face. So I have some questions please: 1.  What is the purpose of storing the old kernel versions?</blockquote><div> In case a new kernel deactivates one of your hardware devices, you can boot with a previous working kernel.     2.  Any reason why I should not delete the oldies?  (And/or maybe justsave the last superseded one?) You can delete if you know which one you want to delete.  I always keep two.     3.  How would I go about deleting them? </div><div> You can either open the boot menu (sudo gedit /boot/grub/menu.lst) and alter the number of displayed kernels to "2" rather than the default of "All" (this will not remove anything but merely remove them from display) or you can install-StartUp Manager (sudo apt-get install startupmanager) which will give you a GUI. While you are there, in either method, you can also shorten the boot delay time from the default 10 seconds to (say) 3 seconds.   Andre </div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> ubuntu-au mailing list <a href="mailto:ubuntu-au@lists.ubuntu.com">ubuntu-au@lists.ubuntu.com</a> <a href="https://lists.ubuntu.com/mailman/listinfo/ubuntu-au" target="_blank">https://lists.ubuntu.com/mailman/listinfo/ubuntu-au</a> </blockquote></div>
