Ubuntu – How to upgrade the Linux kernel to version 3.4.7

You could update your kernel to v3.5.4 by installing a mainline kernel.

Do mainline kernel builds include Ubuntu specific drivers?

By definition the mainline kernel builds are made from virgin unaltered mainline kernel sources and therefore do not, and should not, include any Ubuntu patches or drivers. There are also no binary drivers for these kernels.

Open a terminal and do the following:

mkdir v3.5.4-quantal
cd v3.5.4-quantal
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.5.4-quantal/linux-headers-3.5.4-030504_3.5.4-030504.201209142010_all.deb

Only for 32 bit systems:

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.5.4-quantal/linux-headers-3.5.4-030504-generic_3.5.4-030504.201209142010_i386.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.5.4-quantal/linux-image-3.5.4-030504-generic_3.5.4-030504.201209142010_i386.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.5.4-quantal/linux-image-extra-3.5.4-030504-generic_3.5.4-030504.201209142010_i386.deb

Only for 64 bit systems:

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.5.4-quantal/linux-headers-3.5.4-030504-generic_3.5.4-030504.201209142010_amd64.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.5.4-quantal/linux-image-3.5.4-030504-generic_3.5.4-030504.201209142010_amd64.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.5.4-quantal/linux-image-extra-3.5.4-030504-generic_3.5.4-030504.201209142010_amd64.deb

Install the kernel.:

sudo dpkg -i *.deb

The first HWE kernel will ship with Ubuntu 20.04.2, currently no date for that is available (see https://wiki.ubuntu.com/FocalFossa/ReleaseSchedule) but it'll occur after 20.10's release as it'll be 19.10's kernel that gets used.

Ubuntu 20.10 is scheduled to be released 22-October-2020 (https://discourse.ubuntu.com/t/groovy-gorilla-release-schedule/15531) so it'll be after that.
