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
