Yes. Looking back at your system messages, your screen is not seen as connected. This means that the HPD is not asserted. This may be a HDMI cable problem... There may also be a clock problem. Recently, I tried to stop the HDMI clock (not the DDC one). In this case, the HDP is not detected. So, may you check the 3 clocks (bus, main and DDC). -- Ken ar c'hentañ | ** Breizh ha Linux atav! ** Jef | http://moinejf.free.fr/ -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.
