I installed Ubuntu JeOS on an Artigo Pico-ITX, and wanted to run it headless so I needed to enable the serial console. Ubuntu JeOS uses upstart as per normal Ubuntu releases (rather than sysvinit like other distros) and instructions vary depending on which Ubuntu release you have. Ubuntu 9.10 (Karmic Koala):
Paste the following into /etc/init/ttyS0.conf # ttyS0 - getty
#
# This service maintains a getty on ttyS0 from the point the system is
# started until it is shut down again.
start on stopped rc RUNLEVEL=[2345]
stop on runlevel [!2345]
respawn
exec /sbin/getty -L 115200 ttyS0 vt102 then start the service by typing sudo start ttyS0
Ubuntu 9.04 (Jaunty Jackalope):
Paste the following into /etc/event.d/ttyS0 # ttyS0 - getty
#
# This service maintains a getty on ttyS0 from the point the system is
# started until it is shut down again.
start on runlevel 2
start on runlevel 3
start on runlevel 4
start on runlevel 5
stop on runlevel 0
stop on runlevel 1
stop on runlevel 6
respawn
exec /sbin/getty 115200 ttyS0
To connect to the serial console you will need a NULL modem cable, a terminal that supports a baud rate of 115200 bps 8N1, and the flying lead provided with the Artigo (see photo below).
You can also get grub's output on the serial console by following the instructions further down the page but I didn't bother. |
