Red Hat Bugzilla – Bug 137471
Installer doesn't offer resolutions to match monitor
Last modified: 2008-08-02 19:40:32 EDT
Description of problem:
HP Pavillion zd7260us
17" widescreen display
NVIDIA GeForce FX Go5700
1. During the install, specify the monitor as a generic laptop
monitor that supports 1680x1050.
2. Click the combo box to select a resolution.
3. There are no appropriate widescreen resolutions available, not
even 1680x1050 (the one specified in the name of the monitor).
To make matters even worse, if you select 1600x1200 (which I did),
when the desktop starts up the bottom of the screen (containing all
the actions necessary to do anything - including logging out!) is not
visible. To further complicate things, X doesn't scroll the desktop
if you mouse to the edge of the screen (as I've seen it do when this
happens in other distros).
These factors make installing FC3Test3 on a widescreen laptop pretty

Adding UseModes support for non-standard ratios is todo for FC4
Can you paste the output of running as root
kudzu -p -b ddc
Widescreen laptops are available pretty much everywhere these days. I
just walked into a brick and mortar store and bought one. So it's a
bit of a stretch to call them "non-standard" ratios. I prefer to call
them "current", "new", or "sweet-assed". :)
Anyway, FC3 is totally unusable on this laptop anyway. No network
(wireless) support, no video (this crappy resolution problem), and no
power management. :-/
This seemed like the simplest to fix of the problems. I expected it
would just require a couple lines of text in a metadata file
somewhere; figures everything has to be harder than that.
Anywho, here's the "kudzu -p -b ddc" output:
desc: "NVIDIA Corporation NV36 Board - e183n-sw"
Possibly however it's non-standard in terms of the basic X modes used.
Time constraints meant that the additional work for this did not make
FC3, I fully intend to try and release an errata/update as soon as I
can post un-freeze.
I can't comment for your laptops wireless support - I assume it's a
mini-pci card of the Broadcom chipset which there are no OSS drivers
for, as for power managment it depends on the ACPI implementation of
the laptop - it may be possible to get S3 suspend working but you'll
probably have to use th proprietory NVidia driver.
The panel is unprobable as we only get video card details from DDC.
Can you test the following:

and change the Section "Monitor" block to contain the line:
Then in the Display section ensure you have the desired 1680x1050 mode
Does this provide the desired resolution filling the panel?
Yep. That gives me the resolution to match the monitor.
Fedora Core 3 is now maintained by the Fedora Legacy project for security
updates only. If this problem is a security issue, please reopen and
reassign to the Fedora Legacy product. If it is not a security issue and
hasn't been resolved in the current FC5 updates or in the FC6 test
release, reopen and change the version to match.
Does this work any better in xorg-x11-server 1.1.1-24 or later?
Closing per lack of response to previous request for information.
This bug was originally filed against a much earlier version of Fedora
Core, and significant changes have taken place since the last version
for which this bug is confirmed.
Note that FC3 and FC4 are supported by Fedora Legacy for security
fixes only. Please install a still supported version and retest. If
it still occurs on FC5 or FC6, please reopen and assign to the correct
version. Otherwise, if this a security issue, please change the
product to Fedora Legacy. Thanks, and we are sorry that we did not
get to this bug earlier.
