Linux Kernel

Linux Kernel 5.10 was released a day ago as the latest LTS (Long Term Support) release. Here’s how to install in Ubuntu & Linux Mint.

Linus Torvalds announced the release of Kernel 5.10: “Ok, here it is – 5.10 is tagged and pushed out. I pretty much always wish that the last week was even calmer than it was, and that’s true here too. There’s a fair amount of fixes in here, including a few last-minute reverts for things that didn’t get fixed, but nothing makes me go “we need another week”. Things look fairly normal.

Kernel 5.10 features include:

  • New hardware support including Intel Rocket Lake and Alder Lake
  • AMD Zen 3 temperature monitoring support.
  • Raspberry Pi VC4 support
  • The Creative Labs SoundBlaster AE-7 sound card support.
  • Nintendo Switch controller support
  • Initial support for NVIDIA Orin.
  • AMDGPU DC display support for GCN 1.0 (Southern Islands) GPUs.
  • And much more other changes.

How to Install Linux Kernel 5.10 in Ubuntu:

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

For a graphical tool to install mainline kernel packages, try Ubuntu Mainline Kernel Installer.

[/ac-box]

The mainline kernel packages for Linux 5.10 (64-bit) are now available for download at the link below:

Download Kernel 5.10

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

  1. linux-headers-5.10.0-xxxxxx_all.deb
  2. linux-headers-5.10.0-xxx-generic(/lowlatency)_xxx_amd64.deb
  3. linux-modules-5.10.0-xxx-generic(/lowlatency)_xxx_amd64.deb
  4. linux-image-xxx-5.10.0-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/v5.10/amd64/linux-headers-5.10.0-051000_5.10.0-051000.202012132330_all.deb

wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.10/amd64/linux-headers-5.10.0-051000-generic_5.10.0-051000.202012132330_amd64.deb

wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.10/amd64/linux-image-unsigned-5.10.0-051000-generic_5.10.0-051000.202012132330_amd64.deb

wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.10/amd64/linux-modules-5.10.0-051000-generic_5.10.0-051000.202012132330_amd64.deb

sudo dpkg -i *.deb

Once installed, restart your computer and enjoy!

Uninstall Linux Kernel 5.10:

Restart your machine and select boot with the previous kernel in boot menu ‘Grub2 -> Advanced Option for Ubuntu’. Then run command to remove Linux Kernel 5.10:

sudo dpkg --purge linux-image-unsigned-5.10.0-051000-generic

gnome shell

In the default Gnome desktop when you trying to open an application, the app window sometimes does not get into focus immediately, instead it pops up ‘xxx’ is ready notification and opens the window behind the current focused window.

This usually happens when another window is getting focused during the process of launching a desired application.

To get rid of the ‘Window is ready’ notification and focus window immediately, I think a quick enough system response should fix the problem. Besides, you can install “Focus my window” Gnome extension.

1.) Open terminal (Ctrl+Alt+T) and run command to install chrome-gnome-shell package if you don’t have it.

sudo apt install chrome-gnome-shell

2.) Then go to the extension web page in your browser. Turn on the toggle icon and install it.

NOTE: The old extension is no longer exist. The new one supports only GNOME 45 and 46 so far, meaning for Ubuntu 23.10 and Ubuntu 24.04!.

Don’t see the toggle icon? Click the link “Click here to install browser extension” and finally refresh the page.

That’s it. Enjoy!

(Optional) If you want to remove the gnome shell extensions, either turn off the toggle icon in the web page, or use either Extensions or GNOME Extensions Manager (both available in the new App Center app) utility.
