Re: What means width too large for virtual size
I'm afraid that its still not at all clear what you're trying to accomplish here. Do you want 1080i on both displays?
How did you obtain the 1920x1080ios modeline that you're using (which seems to work according to X)?
Please explain what you'd like to do, and then I can try to assist in accomplishing it.
Please start X with the following command:
startx -- -logverbose 5
and then generate and post a new bug report.
