I'm trying to reinstall Android on my first-gen Nexus 7. I'm using adb to do so because the install is so corrupted I can't even use the touch screen.

I use Ubuntu 13.10 and I have adb and fastboot installed. My Nexus is plugged in. This is what I type:

sudo adb kill-server
sudo adb start-server
adb devices

And... nothing shows up. How do I fix this?

Try running "sudo adb devices". Or, fix your udev rules so that the USB device is writable by your user (see the link in caffinatedmonkey's comment)

Use PTP option instead of MTP USB PC Connection.
