LinuxQuestions.org - Displaylink and Samsung C23A750X Issues (kernel 3.4.0 and 3.4.2)

Currently attempting to get a wireless (or wired) usb hub/display setup working on my notebook.

Started off following the Wiki

Configuring the kernel
cat /usr/src/linux/.config | grep UDL:

Code:

CONFIG_DRM_UDL=m

CONFIG_FB_UDL=m

automatically loading modules on boot
/etc/conf.d/modules:

Code:

# You can define a list modules for a specific kernel version,

# a released kernel version, a main kernel version or just a list.

# The most specific versioned variable will take precedence.

#modules_2_6_23_gentoo_r5="ieee1394 ohci1394"

#modules_2_6_23="tun ieee1394"

#modules_2_6="tun"

#modules_2="ipv6"

#modules="ohci1394"



# You can give modules a different name when they load - the new name

# will also be used to pick arguments below.

#modules="dummy:dummy1"



# Give the modules some arguments if needed, per version if necessary.

# Again, the most specific versioned variable will take precedence.

#module_ieee1394_args="debug"

#module_ieee1394_args_2_6_23_gentoo_r5="debug2"

#module_ieee1394_args_2_6_23="debug3"

#module_ieee1394_args_2_6="debug4"

#module_ieee1394_args_2="debug5"



# You should consult your kernel documentation and configuration

# for a list of modules and their options.



modules="nvidia udlfb udl"

Loading udlfb with fb_defio=1
/etc/modprobe.d/displaylink.conf:

Code:

options udlfb fb_defio=1

I was only able to install x11-drivers/xf86-video-fbdev driver (for some reason layman and Gentoo packages does not show x11-drivers/xf86-video-displaylink as existing anymore??)

SIDE NOTE:
I attempted to install the freedesktop.org drivers but runinto make errors (I am not too experienced with directly compiling packages):

When I plug in both the USB cable and the wireless dongle nothing happes (a green screen is susposed to show on the monitor)

Further diagnosis reveals the device is not being fully recognized by my system and /dev/fb1 is not being created
NOTE: fb0 has always been on my system
