Hello I am wondering if there is currently any possbility to completely turn off the whole video subsystem, while leaving the cpu running? [and is it also possible to "reclaim" the video RAM for the system BTW ?]
That's for a screenless OLPC I'm experimenting with, and for which there's no need to power the non-existent screen :-) So I'm curious to try ; according to http://wiki.laptop.org/go/Hardware_Power_Domains, I guess it should also be possible to power down the DAC, video misc register and graphic processor. How can it be done? Is there an entry in /sys? So far even dcon refuses to go into sleep : echo 1 > /sys/devices/platform/dcon # sleep $ cat /sys/devices/platform/dcon/sleep 0 The ec buttons are now working fine however. Another question : what is the status of ec-wakeup, to replace rtc-wakeup?
