Description Paul Ross 2012-01-06 23:48:01 UTC 
Description of problem:

New Macbook Air 2012 editions come with "Intel HD Graphics 3000" graphics cards. However, after installing Fedora 16 the selectable screen resolutions are limited to a single 1024x768 rather than the 1366x768.

Version-Release number of selected component (if applicable):

Fedora 16

kernel-3.1.6-1.fc16.i686
xorg-x11-drv-intel-2.17.0-4.fc16.i686

How reproducible:

100%

Steps to Reproduce:
1. Take a new Macbook Air 2012 (feature Intel HD Graphics 3000)
2. Install Fedora 16
3. Go to Applications / System Tools / system settings / Displays
4. Note that only 1024 x 768 available

Actual results:

Only 1024x768 resolution available

Expected results:

1366x768 should be available

Comment 1 Adam Jackson 2012-02-13 17:16:34 UTC 
Do you still see this with newer kernels?  If so, please attach full dmesg and Xorg.0.log.

Comment 3 Paul Ross 2012-02-23 13:25:32 UTC 
This has been fixed on later kernels 3.2.6-3 and verified as no working. Requires removing "nomodeset" from the boot parameters.
