How to upgrade ubuntu 12.04 / 13.04 and linux mint 14 / 15 to linux kernel 3.11

I just upgraded xubuntu 12.04 LTS on my laptop to linux kernel 3.11 (ubuntu 13.10 saucy kernel). Everything seems to be a bit faster, due to some new features in Linux kernel 3.11.

What new/hot in linux kernel 3.11 from Linus Torvalds?

• Zswap was merged for compressed swap caching
• AMD Radeon DPM Support
• Low Latency Network Polling
• KVM/ Xen support for 64-bit ARM
• F2FS file-system updates
• EXT4 file-system updates

For x32 system

$ su -
# cd /root/3.11kernel
# wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.11-saucy/linux-headers-3.11.0-031100-generic_3.11.0-031100.201309021735_i386.deb
# wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.11-saucy/linux-headers-3.11.0-031100_3.11.0-031100.201309021735_all.deb
# wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.11-saucy/linux-image-3.11.0-031100-generic_3.11.0-031100.201309021735_i386.deb

For x64 system

$ su -
# cd /root/3.11kernel
# wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.11-saucy/linux-headers-3.11.0-031100-generic_3.11.0-031100.201309021735_amd64.deb
# wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.11-saucy/linux-headers-3.11.0-031100_3.11.0-031100.201309021735_all.deb
# wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.11-saucy/linux-image-3.11.0-031100-generic_3.11.0-031100.201309021735_amd64.deb

For both 32-bit & 64-bit, run below command to install them:

# dpkg -i *.deb
# update-grub
# reboot

Check your system after reboot if you have linux kernel 3.11

$ su -
# uname -r

or

# cat /proc/version

You should see something like this

# uname -r
3.11.0-031100-generic

# cat /proc/version
Linux version 3.11.0-031100-generic (apw@gomeisa) (gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5) ) #201309021735 SMP Mon Sep 2 21:36:21 UTC 2013
