mhwd-kernel

manages Linux kernel installation and removal on Manjaro Linux

TLDR

Show the kernels Manjaro offers

$ mhwd-kernel --list

Show which kernels are already installed

$ mhwd-kernel --listinstalled

Install another kernel alongside the current one

$ sudo mhwd-kernel --install [linux66]

Install one and remove the running kernel in the same step

$ sudo mhwd-kernel --install [linux66] rmc

Remove a kernel you no longer boot

$ sudo mhwd-kernel --remove [linux61]

SYNOPSIS

mhwd-kernel [options] [kernel] [rmc]

mhwd-kernel manages Linux kernel installation and removal on Manjaro Linux. It simplifies the process of installing multiple kernels and switching between LTS (Long Term Support) and mainline kernel versions.Kernel names follow the pattern linux followed by the version number (e.g., linux515, linux61, linux66). The tool automatically handles kernel modules and headers alongside the kernel itself.The rmc (remove current) option is useful when replacing a problematic kernel: it removes the currently running kernel after successfully installing the new one and after a reboot.

PARAMETERS

-l, --list

List all available kernels from repositories

-li, --listinstalled

List all currently installed kernels

-i, --install _kernel_

Install the specified kernel

-r, --remove _kernel_

Remove the specified kernel

rmc

Remove the current kernel after installing the new one

CAVEATS

Always keep at least one known-working kernel installed. Removing the only installed kernel can make the system unbootable. After installing a new kernel, reboot to activate it. Kernel updates may require rebuilding third-party modules (like NVIDIA drivers).
