Updating kernel how to
This terminal command will give your system's kernel information: Tip: mhwd-kernel will automatically update a newly installed kernel with any modules currently used in your existing kernel.For example, if you were to update from kernel 4.14 to 4.19, mhwd-kernel would automatically update 4.19 with any and all modules present in 4.14. Manjaro not only supports the use of multiple kernels (selectable from the boot screen), but allows easy access to the very latest bleeding edge kernels as well.It is recommended - especially if updating to the latest bleeding edge kernel - to keep your old one, even if only for a short time afterwards.This the safer option, and the old kernel can be easily removed when satisfied with the stability and functionality of the new one.
During normal operations, the kernel is responsible for performing two important tasks: To do this, the kernel communicates with the hardware through the drivers that are built into it or those that can be later installed as a module.
New kernels can be installed by pressing the "Install" button.
All necessary kernel modules will be installed automatically with a new kernel as well.
It is also worthwhile noting if Manjaro is being run in a virtual machine (e.g.
Oracle Virtualbox), you may not be able to delete certain kernels if they contain elements important to the virtualisation process itself.
