I'm using an HDTV which can only handle certain particular resolutions. I have figured out how to edit /etc/X11/XF86Config-4 to ensure that the GUI is in a good resolution (1280x960 interlaced, with custom timings).

However, if I use Ctrl-Alt-F1...F6, then it uses some other resolution--I think maybe 1024x768. This is NOT a resolution which my HDTV can accept. I'd like to modify it so that the text consoles use 640x480 resolution, with my own custom timings.

Any ideas what to change to make the consoles use the resolution I want? Maybe I should modify XF86Config? The text console is my failsafe in case I mess up things, so I'm wary of experimenting with it without a clue whether I'm even modifying the correct file.

Thanks!
