Re: ***working*** modelines for xfree86 with official nvidia driver

Desmond, thanks for you great help. I´m here to test the modelines for Xfree 
and framebuffer too, ok?
So, my videocard is a Geforce 4 MX integrated. I don´t know if it can 
support interlace modes. I´ll try it.

I didn´t understand about X11 and Advancedmame. I need to generate a 
modeline for X11 and the same
modeline (different output) for Advancedmame? Is that?

Another problem that I have. I´d like to generate perfect modelines, to 
avoid tear effects, etc. So,
which parameters I need to give to lrmc to have these modelines?

And you will put some modelines at lrmc site? This is good, because it´ll 
serve as base for me and other users.
