MediaBox Setup
This is old from 2010 and probably needs some updates:
aptitude install nvidia-glx-173
aptitude -y purge samba
aptitude -y purge bluez bluetooth gnome-bluetooth bluez-utils
aptitude -y purge cups bluez-cups cups-driver-gutenprint foo2zjs foomatic-db foomatic-db-engine ghostscript-cups hpijs hplip openprinting-ppds pxljr splix
apt-get -y purge evolution evolution-common
aptitude -y purge openssh-server
dpkg -l | grep openoffice | awk '{print \$2}' | xargs aptitude -y purge language-support-en language-support-writing-en python-uno
aptitude -y install sysstat
aptitude -y install unrar
aptitude -y install libdvdread4
/usr/share/doc/libdvdread4/install-css.sh
Remote control
as root:
mkdir /var/run/lirc # it wouldn't create it and it wouldn't start without it on ubuntu
aptitude -y install dvb-utils
Cyberlink remote shows us as /dev/input/event3 according to google.
Can cat that or after installing dvb-utils, can do:
evtest /dev/input/event3
except dvb-utils has no install candidate and tells you to instead get dvb-apps which is already installed and doesn't have evtest, only the c file for it
less /proc/bus/input/devices
remote control is detected as a keyboard so a bunch of stuff just works out of the box.
Should use xmodmap to add the remaining buttons to do things I want
