I am running Intrepid Ibex on a PS3, but unfortunately the screen resolution is so lousy (maybe 540×300 at best) that the screen is enormously compacted. I like Ubuntu, but not like this. I have an HDTV that supports 1080i, I think, but it’s connected to the PS3 via RCA composite cables, the TV doesn’t have an HDMI slot. How do I change the screen resolution in Ubuntu on the PS3? I would really appreciate your useful information regarding this. Thanks.
