Enable PCI hotplug in kernel so FN keys work on Asus Laptops

Some FN+x functions do not work on Asus laptops because asus-wmi and asus-nb-wmi are not present in the qubes kernel. FN+ (f3+f4) buttons for Backlit keyboard do not work. FN+ (f9) button for Touchpad disable does not work. The reason asus-wmi and asus-nb-wmi are missing is because qubes “intentionally” disables PCI hotplug for security reasons (make it harder to perform DMA attack by plugging in ExpressCard/Thunderbolt device). My laptop doesn’t even have an ExpressCard slot or a thunderbol…

So you need to build the kernel modules or kernel yourself.

Or maybe you can install this in dom0 but I don’t know if it’ll work:
