Red Hat Bugzilla – Bug 440711
1360x768 selected instead of 1680x1050 native panel res when using i915.modeset=1
Last modified: 2009-06-10 11:08:35 EDT
Description of problem:
Xorg chooses a suboptimal mode when using i915.modeset=1. Native panel
resolution is 1680x1050 which does get used normally when modeset=0, but
1360x768 is selected instead with modeset=1. This happens on both RHGB and GDM
X server instances, with or without any xorg.conf. Using xrandr to change the
resolution back to 1680x1050 works fine.
Version-Release number of selected component (if applicable):
Thinkpad T61, Intel GM965 graphics.

without i915.modset, Xorg.0.log running with no config, everything works correctly
I'm seeing this on a T60 with i945 as well (instead of 1400x1050).
Changing version to '9' as part of upcoming Fedora 9 GA.
More information and reason for this action is here:
Using Rawhide with the latest kernel (2.6.29-0.124.rc5.i586) modesetting for Intel (apparently on by default now), I am getting 1024x768 instead of the native 1200x960 (on a Dell D430 notebook with Intel 945 graphics).
I suspect this is because it thinks a TV output is attached that actually isn't. Any logs from boot?

This message is a reminder that Fedora 9 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 9. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '9'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 9's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 9 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
