Comment (by kallisti5):
hm... Looking over the syslogs... the modesetting DPMS powerdown / powerup
performs a lock before powerdown and an unlock after powerup.
{{{
KERN: radeon_hd: encoder_output_lock: true
KERN: radeon_hd: display_crtc_lock
KERN: radeon_hd: encoder_dpms_set: power: false
KERN: radeon_hd: encoder_dpms_set_dig: power: false
}}}
{{{
KERN: radeon_hd: encoder_dpms_set: power: true
KERN: radeon_hd: encoder_dpms_set_dig: power: true
KERN: radeon_hd: transmitter_dig_setup
KERN: radeon_hd: transmitter_dig_setup: table 1.1
KERN: radeon_hd: encoder_pick_dig
KERN: radeon_hd: display_crtc_lock
KERN: radeon_hd: encoder_output_lock: false
}}}
However the DPMS call at the end of the syslog doesn't seem to do this
lock / unlock. Not 100% sure, however that looks.. "off"
