The OS is Ubuntu 18.04.5

I want to use GA kernel.

SO I do these operations:

it@it51:~$ sudo apt install linux-generic

Then reboot the machine.

I uninstall HWE kernel:

it@it51:~$ sudo apt-get purge linux-image-generic-hwe-18.04
it@it51:~$ sudo apt-get remove linux-generic-hwe-18.04
it@it51:~$ sudo apt-get remove xserver-xorg-hwe-18.04

Then reboot the machine.

Then I use this command:

it@it51:~$ sudo hwe-support-status
Your Hardware Enablement Stack (HWE) is supported until April 2023.

Does the above paragraph (Your Hardware Enablement Stack (HWE) is supported until April 2023) show that I have not disabled hwe-support successfully?

What method can I use to disable hwe-support successfully?

There's a page over at ubuntu.com, which details downgrading to the GA kernel for 20.04. They don't have specific instructions for 18.04, but they look like they should be the same:

To downgrade from HWE/OEM to GA kernel:

sudo apt install --install-recommends linux-generic

If NVIDIA drivers are required check appropriate level and install them:

ubuntu-drivers list

And then install appropriate NNN version of the drivers:

sudo apt install --install-recommends linux-modules-nvidia-NNN-generic

Reboot, interrupt grub, in advanced options elect to boot 5.4 based kernel, complete boot. Check that everything works as expected.

If everything is good, you may remove the other kernel flavours:

sudo apt remove --purge linux-generic-hwe-20.04 linux-oem-20.04 linux-hwe-* linux-oem-* linux-modules-5.1* linux-modules-5.8.0-* linux-modules-5.6.0-*

  • Advice: Use the string in the below line to replace " linux-modules-5.1* linux-modules-5.8.0-* linux-modules-5.6.0-" within the above command $(dpkg -l linux-modules-5 | grep -v linux-modules-5.4. ) – Bill Zhao Apr 17 '22 at 10:31
  • the line should be: dpkg -l linux-modules-5* | ....
    • is missing... it cannot be shown
