The fourth point release Ubuntu 18.04.4 LTS has been released. Here’s how to install a new Linux kernel 5.3 and Xorg on your current Ubuntu 18.04 machine.
Ubuntu 18.04.4 comes with an updated Hardware Enablement Stack (HWE) from Ubuntu 19.10. This includes kernel 5.3, which enables the latest hardware and peripherals from IBM, Intel and others.
It was Announced last night:
The Ubuntu team is pleased to announce the release of Ubuntu 18.04.4 LTS (Long Term Support) for desktop, server and cloud products, as well as other types of Ubuntu with long term support.
Like the previous LTS series, 18.04.4 includes a hardware enablement stack for use with new hardware. This support is provided on all architectures and is installed by default when using one of the desktop images.
Ubuntu Server installs the GA kernel by default. However, you can select the HWE kernel from the installer boot loader.
How to upgrade to Ubuntu 18.04.4:
In addition to downloading the ISO image, installing all available updates via Software Updater will display the latest point release of the current Ubuntu 18.04 machine.
If you have never installed the Hardware Enablement Stack on an Ubuntu 18.04 machine, you can also:
To install the 5.3 kernel, you may need to run the following command in a terminal:
sudo apt-get install --install-recommends linux-generic-hwe-18.04
Or run the command to install both the new kernel and the Xorg server stack.
sudo apt-get install --install-recommends linux-generic-hwe-18.04 xserver-xorg-hwe-18.04
Once installed, restart and enjoy!
To delete a new hardware enablement stack:
To remove the new v5.3 kernel, first reboot and select the old kernel from Grub Boot Loader> Advanced Options. Next, execute the command.
sudo apt remove linux-image-unsigned-5.3*generic linux-image-5.3*generic
To remove a new Xorg package, execute the following command:
sudo apt remove xserver-xorg-*-hwe-18.04
Then you need to reinstall the old xorg package using the command.
sudo apt install xorg
