## 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
|
