0000184: HDMI output turns off on inactivity
HDMI output seems to turn off if the screen stays unchanged for an amount of time. Only returns on reboot.

Most probably related to sunxi kernel 3.4. The following workaround helps:

/etc/kbd/config:
BLANK_TIME=0
BLANK_DPMS=off
POWERDOWN_TIME=0
No tags attached.

When using X the display still turns off if the workaround is used.

I added the following:
/etc/X11/Xsession.d/90x11-common_xset:
xset dpms force on
xset s off

This seems to work at least some of the time (possibly not with fbturbo, haven't tested too much).
