How To Reload All Kernel Modules And List Required Moduels for Each Device - Linux Mint Debian Ubuntu Troubleshooting

One easy way is to use lspci -k like this:

sudo lspci -k|grep modules|sort -nr|uniq
    Kernel modules: snd_hda_intel
    Kernel modules: shpchp
    Kernel modules: pata_acpi
    Kernel modules: nvidiafb, nouveau, nvidia_drm, nvidia
    Kernel modules: mei_me
    Kernel modules: lpc_ich
    Kernel modules: isci
    Kernel modules: ioatdma
    Kernel modules: i2c_i801
    Kernel modules: e1000e
    Kernel modules: ahci
 

This is a great way of troubleshooting what modules your system actually needs and uses.  It's also good for troubleshooting in the case that a device like a NIC or soundcard does not work.  It could be that the kernel module is missing and this is an easy way of finding it.

That is the clean version but you could use the full output to understand which device each module is related to.

Let's say you wanted to load the e1000e NIC driver, you would use "modprobe e1000e".  If it didn't work or was not found, then you know the issue is a missing kernel module.  This either means your kernel does not support the device OR it does not have all of the kernel modules available, installed.

See this for how to install 'extra' kernel modules
