Unable to get true 1920x1200 resolution with Fedora 8
During a recent re-install to Fedora 8, I have found that the 1920x1200
resolution that I had in Fedora 7 has been lost. Even with the
915resolution hack, the resolution still is off. From what I can guess,
it looks like 1280x1024 or 1440x900. Has anyone had success achieving
this resolution, if so how?
I did notice a few peculiarities. First, I was able to get a resolution
close to (if not exactly) 1920x1200 after futzing with the screen
resolution in the GUI, logging out, logging back in. The couple times I
saw the "good" resolution, I had reduced my screen resolution setting,
restarted, then updated the screen resolution to 1920x12000 and clicked
apply. After the next login, the resolution was back to its reduced
version. I also notice that each time I login, the resolution appears
to magnify as the fonts/icons are being loaded. The text generally
shows up first in a smaller form, and then magnifies as everything is
loaded. I don't know whether either of these two points are relevant,
but I did find them unusual.

No problem w/ a D810 WUXGA screen (+ Ati X600), 1920x1200 w/o the need
to change the X config. In my case it's an install from scratch.

What I've found to be odd is that the Fedora 8 install dropped me in to
what it describes as a 1920x1200 resolution, but it is obviously not.*
I was just able to replicate the "phenomenon" that allows me to get a
temporary 1920x1200 resolution.* Here are the steps to reproduce:
1) Using init level of 3, run startx.
1) Change the screen resolution (not disply settings) to a lower
resolution
2) kill the gnome session (ctrl+alt+backspace)
3) start back up the X environment (startx)
4) Go back to the screen resolution preferences, and change back to
1920x1200 and click apply.
5) My resolution appears to be correct for now, but once I logout and
log back in, I will be back to a crappy resolution (1280x960 or similar
I think).

I feel more lucky than you are, here are some excerpts of my xorg.conf:
as you can see, X.org and the radeon driver apparently get the right
max screen size w/o any specific settings.

I've seen that sort of thing before with the video drivers
thinking I have a dual display and wanting to run at the lowest
resolution it imagines either display has. Don't know what
kind of options the intel driver takes, but perhaps there is
a way to explicitly tell it there is only a single display?
(Or perhaps that isn't the problem at all :-).

I am curious, by what method do you know you are not at 1920x1200, and at what
resolution you are really at ????
xdpyinfo???
It looks like, from your Xorg.0.log if I interpreted it correctly, that you

Todd, that would explain why my Display Settings and Resolution settings
both say 1920x1200. The reason I know it is not that actual resolution
is twofold. First, I had Fedora 5, 6 and 7 installed on this laptop, so
I've grown accustomed to a particular resolution setting. Secondly,
this same laptop is being used by another user with a Windows XP
installation, and the differences between resolutions are night and
day. That said, I've attached the 2 different outputs of xdpyinfo. One
when I've acheived what I believe is 1920x1200 resolution, and one when
it is defaulted back to 1280x960 (i think). They are identical outputs,
but the display is completely different. I can send screenshots to
anyone who's interested.
I did manage to find an article that *may* be related:
https://bugs.launchpad.net/ubuntu/gutsy/+source/xserver-xorg-video-intel/+bug/15131
I'm attempting some of the user suggestions for this bug, but so far
nothing has managed to correct the issue.

I finally have my old resolution back. Here's what I did in order to
get it to work.
I followed directions from the following article
(http://bugs.freedesktop.org/show_bug.cgi?id=10304), and found that my
DPI settings in xdpyinfo were sitting at 133x133. I then found that the
following set my DPI back to what I was accustomed to (96).
System -> Preferences -> Look and Feel -> Appearance -> Fonts -> Details
-> 96 dots per inch.
