My problem is that Linardo automatically selects the highest resolution the video projector supports (1920x1080i) and it's really straining my eyes. I've tried modifying xorg.conf (or something like that) to have a mode 1280x720 but the resolution is still that higher one. I've tried quite a few methods of changing the resolution but so far it's a no go. Same thing happens when I connect Udoo directly a monitor. It selects the highest supported resolution which isn't native resolution so everything's a bit blurry. WIth Raspbian this was as easy as adding that mode 1280x720 to config file. So any ideas what to try?
Changing the environment variables during boot-up, using a serial interface with a PC, worked for me. See @Lifeboat_Jim's solution near the end of the following page: viewtopic.php?f=16&t=193&hilit=resolution&start=10
