apt-get install xfce4 xorg synaptic pithos

startxfce4

start pithos and get it working with your usb sound card, once that is working close it and go to the terminal

If you are using an realtek usb wifi adapter following are the instructions I had to follow to get it working:

Grab the modified driver from here:


wget https://realtek-8188cus-wireless-drivers-3444749-ubuntu-1304.googlecode.com/files/rtl8192cu-tjp-dkms_1.6_all.deb)

Find out your current kernel:


uname -a

For me:


Linux arm 3.8.13-bone40

Grab the kernel headers:


wget http://rcn-ee.net/deb/raring-armhf/v3.8.13-bone40/linux-headers-3.8.13-bone40_1.0raring_armhf.deb)

Install those headers:


dpkg -i linux-headers-3.8.13-bone40_1.0raring_armhf.deb

Install the dkms package and all its dependencies:


apt-get install dkms

Install the rtl8192cu-tjp-dkms_1.6_all.deb package. It will fail, don't worry. We installing it for the source files!


dpkg -i rtl8192cu-tjp-dkms_1.6_all.deb

Notice, we need arch armv7l. We'll fix the missing arch files.


ln -s /usr/src/linux-headers-3.8.13-bone40/arch/arm /usr/src/linux-headers-3.8.13-bone40/arch/armv7l

Fix a problem with the timex.h header


vim /usr/src/linux-headers-3.8.13-bone40/arch/armv7l/include/asm/timex.h

change line 18 from

"#include <mach/timex.h>"

to

"#include </usr/src/linux-headers-3.8.13-bone40/arch/arm/include/asm/timex.h>"

Run make to build the driver

cd /usr/src/rtl8192cu-tjp-1.6

make

Copy the new module in to the kernel modules directory


cp 8192cu.ko /lib/modules/3.8.13-bone40/kernel/drivers/net/wireless/

Update the module deps


depmod

Blacklist the native drivers.


vim /etc/modprobe.d/blacklist.conf

add this to the end:


# Blacklist native RealTek 8188CUs drivers
blacklist rtl8192cu
blacklist rtl8192c_common
blacklist rtlwifi

If this was successful you should not have any trouble resolving a network address, and the wifi will stay connected. Additionally, the light on the card should not be constantly lit but rather flashing to indicate traffic.

edit \etc\network\interfaces

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet dhcp
# Example to keep MAC address between reboots
#hwaddress ether DE:AD:BE:EF:CA:FE

# WiFi Example
auto wlan0
iface wlan0 inet dhcp
    wpa-ssid "YOUR_SSID"
    wpa-psk  "YOUR_PASSWORD"
    


# Ethernet/RNDIS gadget (g_ether)
# ... or on host side, usbnet and random hwaddr
# Note on some boards, usb0 is automaticly setup with an init script
# in that case, to completely disable remove file [run_boot-scripts] from the boot partition
iface usb0 inet static
    address 192.168.7.2
    netmask 255.255.255.0
    network 192.168.7.0
    gateway 192.168.7.1

At the end of ~/.bashrc add:

startxfce4

In xfce add Radio.py to the startup programs

#Reboot

** on one install this worked without errors, on another it told me that the jack server was not running, but worked with the usb sound card anyway. I ignored the errors because every thing was working.**

You can’t perform that action at this time.
