11.10 upgrade kernel

Solution 1

Apart from waiting for the kernel to appear in the PPA (it's been released what, a day ago?), another option is to download a tarball and to compile it from sources.

Waiting for a PPA is safe, compiling from sources is fun. You choose :)

Solution 2

Kernels

A bit earlier there was a question: How to downgrade the Kernel on 11.10. Upgrading the kernel is not harder.

You could download the kernel binaries from the old or new Ubuntu releases¹. The Precise² has the 3.1. Also the Kernel Mainline build³ has the 3.1.

Donwloading from the Mainline the linux-image-3.1.0-030100rc10-generic. Installing it. Rebooting with it and the (K)ubuntu 11.10 is running with the 3.1.

I think kernel team have uploaded the 3.1 kernel here http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.1-oneiric/

The Ubuntu kernel PPA doesn't have kernel 3.1. Is there any other guaranteed way to upgrade because I don't want to reinstall Ubuntu again.

+1 for the "fun" part... SPECIALLY that much "fun".

it's actually not difficult to compile kernel from sources, and also it's quite safe - in the worst case, the machine won't boot with the new kernel and you'll have to reboot with the old one. Also, kernel is very self-contained. I mean, compiling and configuring Gnome or KDE is a much more daunting task.

You have tested this? I ask since you make it sound without any doubt easy to apply without any problems after applying it. Just asking to be sure you have tested this.

"You have tested this?" Yes, I have tested this. If there are kernel related problems (or i think that the problem is the kernel): 1 - I check the kernel bug reports. 2 - I will search the net. 3 - I try an older kernel. 4 - I try a newer kernel. 5 - I recompile the kernel with own settings.

I went back to 3.0 cos in 3.1 i had low sound quality (sound isn't pure) and Ubuntu plymouth screen disappeared.
