do you want 4.7.1 in particular or 4.7.2 ?

Okay, open a terminal and run these commands in sequence:
Code: [Select]
mkdir ~/Desktop/kernel-4.7.2
then
Code: [Select]
cd ~/Desktop/kernel-4.7.2
then
Code: [Select]
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.7.2/linux-headers-4.7.2-040702-generic_4.7.2-040702.201608201334_amd64.deb
then
Code: [Select]
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.7.2/linux-headers-4.7.2-040702_4.7.2-040702.201608201334_all.deb
then
Code: [Select]
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.7.2/linux-image-4.7.2-040702-generic_4.7.2-040702.201608201334_amd64.deb
then
Code: [Select]
sudo dpkg -i *.deb
then REBOOT

Once rebooted, check which kernel you're using with

a) because the 4.7 kernel series wasn't available when Peppermint 7 was released.
and
b) because the 4.4 kernel series is the officially supported long-term-support kernel upstream .. so it makes no sense for us to use anything else or we couldn't call Peppermint 7 a "long term support" release (because it wouldn't be).
and
c) there's no 100% guarantee it'll work with all third party drivers and the xorg version frm xenial
and
d) keeping everyone on the LTS kernel makes support more consistent.
and
e) the vast majority of users will not benefit from the 4.7 kernel in any way (cutting their support length for no good reason) .. in fact at this point using it in xenial it's MUCH more likely to cause problems than solve them as xenial/16.04 was built (and tested) around the 4.4 LTS kernel.
