Again, more for my own reference than anybody else’s…
We’re talking Ubuntu here, by the way. I’m on 10.04 on my laptop and just installed 10.10 on the desktop
Problem: lots of Kernel entries in Grub (even had this dropping windows off the list in the old days and thought I’d done something VERY bad to my dual-boot laptop). Also, in the case of my Eeepc, a full root partition with a lot of unnecessary kernels.
I’ve found myself Googling this at least three times because I always forget which name to search for and remove in Synaptic. So here it is:
First, check which Kernel you’re using.
Open a terminal and type
uname -r
My output looked like:
2.6.32-25-generic
So make absolutely sure you don’t delete that one! If you’re conservative, you’ll also keep the revision before too.
Open Synaptic and search for
linux-image
the kernels you have installed will all have green boxes next to them BUT BEWARE, so does your current kernel
remove (in my case)
linux-image-2.6.32.23-generic
linux-image-2.6.32.24-generic
BUT NOT
linux-image-2.6.32.25-generic
Mark the unnecessary kernels for complete removal
You’re done, that’s another job jobbed as my Mum would say
