Rick,
Yes, I got it fixed and it was a lot easier than I thought. You just
have to *slow* down and follow the steps one at a time. Basically, what you
need to do is compile X, mesa and drm from the tarballs and that will leave
you with a fresh X window install in /tmp/modular if you follow the
following instructions. You don't have to worry about screwing up your
system because the new X window install is totally independent of your
present working X setup.
(1) First *read* http://www.intellinuxgraphics.org/install.html
(2) Make sure you have a current version of 'git' installed. Download
and install:
http://www.kernel.org/pub/software/scm/git/git-core-0.99.9i.tar.bz2 and
http://www.kernel.org/pub/software/scm/git/git-1.5.1.2.tar.bz2 and read
http://www.kernel.org/pub/software/scm/git/docs/
(3) Go to: http://intellinuxgraphics.org/download.html and download the
tarballs
(4) Read and *follow* very *closely*:
http://wiki.x.org/wiki/ModularDevelopersGuide That means *step-by-step*
(5) Read and *follow* very *closely*:
http://dri.freedesktop.org/wiki/Building Same cautionary statement
(6) Generate a new modeline using the Linux command line 'gtf' for your
1680x1050 display to put in /etc/X11/xorg.conf: (presuming your lcd runs at
60 MHz)
david at providence:~> gtf 1680 1050 60
# 1680x1050 @ 60.00 Hz (GTF) hsync: 65.22 kHz; pclk: 147.14 MHz
Modeline "1680x1050_60.00" 147.14 1680 1784 1968 2256 1050 1051 1054
1087 -HSync +Vsync
*Remember* your modeline name ( "1680x1050_60.00") must match your
"ModelName" in the "Monitor" section of xorg.conf
(7) Edit /etc/X11/xorg.conf to install the new modeline in "Modes"
section along with the "intel" and dri changes discussed in the links above.
The modeline will be:
Section "Modes"
Identifier "Modes[0]"
Modeline "1680x1050_60.00" 147.14 1680 1784 1968 2256 1050 1051 1054
1087 -HSync +Vsync
EndSection
The DRI section will be:
Section "DRI"
Group "video"
Mode 0660
EndSection
The *primary* thing to remember is to *slow* down and follow the
information in the links *step-by-step*. The folks at Xorg have done a
fantastic job packaging X, mesa and drm with *all* the instructions needed
to build and install a new X setup that will give you a gorgeous 1680x1050
display. Just follow the directions and all will be well in you world.
