[gentoo-user] /etc/modules.d how to understand

[Helmut Jarausch]

Hi,

I'd like to understand the "magic" of files in /etc/modules.d
How to write such an 'alias' line.
Can anybody point me to a HowTo?

E.g. in kernel 2.6.22 there is no more an option to select
a USB-WACOM tablet input.
I've built the kernel module from the linuxwacom project,
but what's the right way to load the module.
(I could do an explicit insmod in /etc/conf.d/local.start
 but that's not the canonical solution, isn't it.)

Many thanks for your help,

Helmut Jarausch

Have you read the manual page for modprobe.conf?  That will tell you
all the relevant options and their syntax, etc.  /etc/modprobe.conf is
generated from the files in /etc/modules.d by update-modules.  modinfo
can tell you what options can be set for any given kernel module.

You can do, but now you need to enable the option for tablet input
devices first.  That will then let the configuration list the tablet
devices available.

: config TABLET_USB_WACOM
:         tristate "Wacom Intuos/Graphire tablet support (USB)"
:         depends on USB_ARCH_HAS_HCD
:         select USB
:         help
:           Say Y here if you want to use the USB version of the Wacom
: Intuos or Graphire tablet.  Make sure to say Y to "Mouse support"
:           (CONFIG_INPUT_MOUSEDEV) and/or "Event interface support"
:           (CONFIG_INPUT_EVDEV) as well.
: 
:           To compile this driver as a module, choose M here: the
:           module will be called wacom.

I would expect udev to handle the module loading for this. That's the
normal way anyway.

I don't know how 'right' this is, but I just'd

echo wacom >> /etc/modules.autoload.d/kernel-2.6

But like Ian says, its there in .22, you just have to look harder. :)
