Linux Kernel

Linux 4.11 Kernel was officially released on April 30th. Linus Torvalds announced in

So after that extra week with an rc8, things were pretty calm, and I’m much happier releasing a final 4.11 now.

We still had various smaller fixes the last week, but nothing that made me go “hmm..”. Shortlog appended for people who want to peruse the details, but it’s a mix all over, with about half being drivers (networking dominates, but some sound fixlets too), with the rest being soem arch updates, generic networking, and filesystem (nfs[d]) fixes. But it’s all really small, which is what I like to see the last week of the release cycle.

Linux 4.11 Kernel release highlights:

  • Enable frame-buffer compression by default for Skylake device and newer.
  • Adds DP MST audio support in Intel’s DRM driver.
  • Initial Geminilake graphics support.
  • ASPEED AST2500 display support.
  • Better Turbo Boost Max 3.0 support.
  • New ARM SoCs and boards support.
  • Realtek ALC1220 is now supported
  • Radeon/AMDGPU and various other DRM driver updates.
  • Improvements and updates to KVM, Xen, TurboStat, Raspberry Pi, TPM2, and more.

How to Install Kernel 4.11 in Ubuntu:

The mainline kernel PPA built the Linux 4.11 build .deb packages a few days later, available for download at the link below:

The mainline kernels do not include any Ubuntu-provided drivers or patches. They are not supported and are not appropriate for production use.

Download Linux 4.11 Kernel (.deb)

You can also use UKUU, a simple graphical tool to install latest Linux Kernels in Ubuntu.

To get Linux 4.11 Kernel from command console, run following commands one by one:

for 64-bit system:

cd /tmp/




sudo dpkg -i *.deb

for 32-bit system:

cd /tmp/




sudo dpkg -i *.deb

After installed these debs, restart and enjoy!


To remove Linux Kernel 4.11, first restart and select boot with previous kernel (from Grub boot-loader -> Advanced Options) and then run command:

sudo apt-get remove linux-headers-4.11* linux-image-4.11*
