Linux Kernel

Linux Kernel 5.11 was released a day ago on Valentine’s Day. Here’ how you can install it in Ubuntu and Linux Mint based systems.

Linus Torvalds announced the Kernel 5.11: “Nothing unexpected or particularly scary happened this week, so here we are – with 5.11 tagged and pushed out.
In fact, it’s a smaller-than-average set of commits from rc7 to final, which makes me happy. And I already have several pull requests lined up for tomorrow, so we’re all set for the merge window to start..”

New features in Linux Kernel 5.11 include:

  • Intel Integer Scaling support
  • Intel async page flipping support
  • Initial support for AMD Green Sardine and Van Gogh APUs
  • Intel WiFi 6GHz band support
  • NVIDIA RTX 30 “Ampere” Support
  • The OUYA game console and other new ARM hardware support
  • Improved USB4 and Thunderbolt support
  • Sound support for Intel Alder Lake
  • Fixed the frequency invariance performance regression for AMD.

How to Install Linux Kernel 5.11:

The Ubuntu Mainline Kernel Archive provides the new kernel packages via DEB files.

For those prefer using a graphical tool, see this tool to install the latest Kernel.

To manually download the mainline kernel packages for Linux 5.11, go to the link button:

Select generic for common system, and lowlatency for a low latency system (e.g. for recording audio):

  1. linux-headers-5.11.0-xxxxxx_all.deb
  2. linux-headers-5.11.0-xxx-generic(/lowlatency)_xxx_amd64.deb
  3. linux-modules-5.11.0-xxx-generic(/lowlatency)_xxx_amd64.deb
  4. linux-image-xxx-5.11.0-xxx-generic(/lowlatency)_xxx_amd64.deb

Alternatively you can download and install the kernel binaries via terminal commands ( open terminal via Ctrl+Alt+T):

cd /tmp/

wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.11/amd64/linux-headers-5.11.0-051100_5.11.0-051100.202102142330_all.deb

wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.11/amd64/linux-headers-5.11.0-051100-generic_5.11.0-051100.202102142330_amd64.deb

wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.11/amd64/linux-image-unsigned-5.11.0-051100-generic_5.11.0-051100.202102142330_amd64.deb

wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.11/amd64/linux-modules-5.11.0-051100-generic_5.11.0-051100.202102142330_amd64.deb

      Tried installing each of the three the low latency 5.11 packages from https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.11/ and each time get the message that the following packages have unmet dependencies (but no packages listed). Ubuntu Studio 20.04 low latency Lenovo Thnkbook G2 15 ARE with AMD 4700u processor.

        i was using linux mint and gets the same error! its related to version of glibc that ubuntu uses. try to use a older kernel, or you need to manually update the glibc library!

          I solved the problem by blowing Ubuntu 20.04 away and installing Ubuntu Studio 21.04. It comes with kernel 5.11.

      do NOT upgrade if you are using the nvidia-340 drivers unless you patch them: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-340/+bug/1916640
