I forwarded the initial question to debian-user, I might as well send this as well. ----- Forwarded message from Hugo van der Merwe <hugovdm@mail.com> ----- From: Hugo van der Merwe <hugovdm@mail.com> To: branden@debian.org Subject: Re: XF86Setup: how are the Modelines generated?

To sort-of answer my own question: I think this is related to the fact that I have a laptop, and the way an LCD screen works. I'm trying to find out more about it now. (It would help to know how XF86Setup gets its modelines - I think xvidtune does the same, it also gets invalid mode lines...) Maybe laptops do not use hsync or vsync at all - and the lct always expects 65.15 dotclock, and the card always gives this - the only problem is that the modes "appear" invalid because of hsync or vsync settings? I am speculating, and have too little knowledge on the matter to know whether I am uttering rubbish. I'll continue my quest for better laptop support on the debian-laptop mailing list.
