Setting up software defined radio in debian...

...is more challenging than I originally expected.

The most helpful site I can find is this one:

Many of my questions were answered with this post:

but alas it would appear that the gnuradio script takes care of much of the former:
$ wget http://www.sbrac.org/files/build-gnuradio && chmod a+x ./build-gnuradio && ./build-gnuradio
 
*I did have to update the build script to include 7.5 for it to run.

No keyboard (doesn't work) after upgrading from Ubuntu 13.04 to 13.10

After upgrading to Ubuntu 13.10 I couldn't enter my password to decrypt my drive. It looks like this is an issue with 3.11 kernel.

The solution is as follows:
1) hold shift when starting the computer
2) when grub loads choose an older kernel (for me it was 3.8)
3) run "sudo gedit /etc/initramfs-tools/modules"
4) add the line "ohci_pci"
5) save the file
6) run "sudo update-initramfs -u"
7) reboot
8) to verify you are running the latest kernel run "uname -r"

I plugged my Linux box into the tv

And I didn't have any sound coming through the HDMI cable. I am currently using Lubuntu and everything else worked perfectly. The problem was I wasn't using the Nvidia drivers. I was seriously hoping to avoid using the Nvidia drivers since it doesn't play well with Lubuntu. All my text ends up super small. Therefore I switched to Ubuntu. 

To get sound over HDMI I had to install pavucontrol:

sudo apt-get install pavucontrol

Then select HDMI as the output.

However my login screen still says Lubuntu. To change it to Ubuntu I issued the following command:

sudo update-alternatives - - config default.plymouth 

And selected the Ubuntu option. The to make the changes permanent issue the following command 

sudo update-initramfs -u

Now logging in says Ubuntu :-)
