Re: FC3 + Dell WUXGA Screen + NVidia = Working Configuration

This is very interesting.

I've been struggling with my Toshiba laptop with a WXGA 1280x800 display. I've seen several xorg.conf files all have issues so I've been trying to figure out the format myself.

My specific question is how do you determine how to write your own ModeLine? Do you have a reference to good documentation on how to make my own?

  I was asked by someone in another thread to post my working xorg.conf
file since this appears to be a common question and mine works.  This
configuration file is working on my Dell Inspiron 8600 w/ the WUXGA screen
and the NVidia drivers (nvidia.com not the nv module).  This sets the
screen to run in the 16:10 aspect mode at 1920x1200, 1680x1050 and 1280x800
resolutions.  This configuration has some extra tweaking with the
DisplaySize directive for the Monitor to make the fonts in KDE look right
but if you're using Gnome, it's unnecessary.  If you have questions or
comments, please CC me directly as I generally read this list in "batch
mode". Please note that some wrapping of lines has most likely occurred in
your mail reader.  Everything except for "Section" and "EndSection" starts
one tab in so anything wrapped starting in column 1 most likely belongs at
the end of the previous line.

  Some notes: I'm not specifying rhgb in grub.conf.  I do not use
xdm/gdm/kdm so this is not tested with those.  I'm setting mode 0600 on
/dev/nv* in /etc/security/console.perms. There appears to be a problem with
GL screensavers running at this aspect/resolution that makes them unusable.
If someone has a fix for this, I'd like it.  This configuration assumes you
have the nvidia.com closed-source drivers properly installed.
