Raspberry Pi
1/1/2013 Happy New Year!
Today I am thinking that this will be used as a car computer.
I got a heavy duty 7 port USB hub for it, a nice cast al box, and now I want to make it work with my Lilliput 7" DisplayLink monitor.
To do that I will need to compile a kernel (ugh! back to doing that again!)

Distro
Try the arch linux option. Gave up on it and went with Debian. Still the best.
DisplayLink kernel build
Some help with kernels and DisplayLink http://karuppuswamy.com/wordpress/2012/08/17/lilliput-displaylink-usb-monitor-um-70-17e902a9-with-raspberry-pi-on-raspbian/
Following Mitchtech kernel compile instructions with a few variations. I am using Linux Mint 14 as my build host. This installs the newest (4.7) compiler and creates symlinks. This step (building a working ARM tool chain) used to take days to figure out. Ah, progress! I love the Linux world I live in!
sudo apt-get install gcc-arm-linux-gnueabi git-core ncurses-dev

Zoom zoom away we go. Put SD card in Pi. Connect monitor and boot. Worked on first try for me! Fabulous.
X11
Before diving in to the above instructions on how to get X11 going, I typed "startx" and it came up! Okay. Moving on. I need the touchscreen to work. It acts like it works but is not calibrated. I am using a mouse at the moment.
