X server log

Description of problem:
The kernel argument "nomodeset" makes X use the Vesa driver for a Nvidia chip that otherwise works with Nouveau.

Version-Release number of selected component (if applicable):
xorg-x11-drv-nouveau-0.0.16-3.20100305git6b8b157.fc13.x86_64
xorg-x11-drv-vesa-2.2.1-2.fc13.x86_64
xorg-x11-server-Xorg-1.8.0-4.fc13.x86_64
kernel-2.6.33.2-41.fc13.x86_64

How reproducible:
always

Steps to Reproduce:
Boot with default kernel arguments plus "nomodeset".

Actual results:
The resolution is 1280×1024, and if I read the log right X uses the Vesa driver.

Expected results:
If Nouveau is intended to work with "nomodeset", then the resolution should be 1920×1200 and the driver should be Nouveau.

There are files in /etc/xorg.conf.d but no xorg.conf.

This is not a bug, you're seeing the correct behaviour.  Nouveau no longer supports userspace modesetting as of F13 (and upstream).
