I've just upgraded from 13.04 to 13.10. I've read in some articles that Ubuntu 13.10 is supposed to have the Linux 3.11 kernel. However the output uname -a states that my kernel is still at 3.9:

Linux joren-8570w 3.9.0-030900-generic #201304291257 SMP Mon Apr 29 16:58:15 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

Do I have to upgrade my kernel manually, or should this have happened / will happen in the future with the Ubuntu upgrade?

Edit: The output of aptitude search linux | grep ^i

Remove the custom 3.9 kernel you've installed before:

sudo apt-get remove linux-\.\*3\.9\.\*

This will remove all packages with a name matching linux-*3.9.*.

During the execution of apt-get it should reload the bootloader configuration, but just to be sure you may run

sudo update-grub

and it should list only the 3.11 kernels with Saucy.

Please note that all the time before you've been running an unpatched kernel. Avoid that next time, unless you know what you're doing, as you'll have to update the kernel yourself if you do that.

I've done all you said, but now my laptop won't start anymore. It doesn't even get to the grub. I've already tried updating the grub from a live cd. –  Joren Oct 17 '13 at 21:19
    
Well, if Grub doesn't even start anymore then you have a broader issue here. Please ask a new question about this. –  gertvdijk Oct 17 '13 at 21:22
