Imho this bug is just 5386: this is the edid based mode injection, but also
offers a CVT generator to the mode code and drivers. This generator function is
of course the current main routine of the cvt utility present in current CVS.
In time, this generator should also be called when a Modes directive, in the
Display subsection of the Screen section, has no corresponding mode in the
modelist (before going through validation). But there are a few hoops to jump
through before i get there.
This would mean that you just state:
Modes "1900x1200"
in xorg.conf. Then, if no-one else has provided that modeline right before
validation, the return value of xf86CVTMode(1900, 1200, 60, FALSE, FALSE); gets
added to the modelist. [(HDisplay, VDisplay, VRefresh, Reduced, Interlaced)]
So this bug actually depends on 5386. So Mike, if the above is how you see
things too, please set the dependency.

Mike Harris at Redhat asked me to file this bug report upstream. The new version of Xorg is not recognizing wide aspect screens properly, requiring users to manually add modelines to the /etc/X11/xorg.conf to get their displays working properly. As an example I have a Dell Inspiron 9300 with a 1920x1200 display. When I run xorg without modifications, (having told it I have a 1920x1200 flat-panel display) it sets up xorg.conf with a wide range of display sizes including wide aspect screens Modes "1920x1200" "1920x1440" "1680x1050" "1600x1200" "1400x1050" "1280x960" "1280x800" "1280x1024" "1152x864" "1024x768" "800x600" "640x480" however, only the following resolutions are avaiable: "1600x1200" "1400x1050" "1280x960" "1280x1024" "1024x768" "800x600" "640x480" It's worth noting that none of the wide aspect options work. Adding the following to my xorg.conf file will allow 1920x1200 to work: # 1920x1200 @ 60.00 Hz (GTF) hsync: 74.52 kHz; pclk: 193.16 MHz Modeline "1920x1200_60.00" 193.16 1920 2048 2256 2592 1200 1201 1204 1242 -HSync +Vsync Mike Harris suggested that "The problem seems to be that the X server does not supply a built in video mode for the resolution you would like to use." The bug at redhat's bugzilla is here: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=174626 What else would you like to know. With regard to versions, I'm using Fedora rawhide builds, so I'm guessing at the version. Hopefully the information below might help to clear up what version I'm using.
