Hi,
May I suggest that you create additional topics in topic section menu of this forum to make it easier for parallella supporters to search and browse for information that is related to their parallella board model. For example, I have parallella board 7010 version with hdmi support. All the issues with hardware and (importantly) linux ubuntu pertaining the 7010-hdmi should be located in that section including software. I think it will be easier for anybody to troubleshoot the future software problems. Since modification for 7020 may not apply to 7010 version.
