## Headless Mode
For servers (ie, no need for a display), uncomment the following in
`/boot/boot.ini` to free up approx 300M of memory at the cost of disabling the
video subsystem:
setenv nographics "1"
## LEDs
ODROIDs have dual LEDs: a red power LED which is always on if power is
supplied, and a blue LED which can be configured.
By default, the blue LED is a heartbeat LED, which flashes when the kernel is
running. This can be configured in `/sys/class/leds/blue:heartbeat/trigger`.
To list available triggers:
# cat /sys/class/leds/blue:heartbeat/trigger
Replace TRIGGER with one of the available triggers. This setting will apply
instantly, but be lost upon reboot.
# echo TRIGGER > /sys/class/leds/blue:heartbeat/trigger
To create a persistent configuration, edit or create
`/etc/tmpfiles.d/leds.conf`:
w /sys/class/leds/blue:heartbeat/trigger - - - - TRIGGER
