Xorg log
As shown in the attached photo, the correctly detected native resolution for my
laptop's LCD (1280x800) is severely distorted when using the nouveau driver.
The framebuffer console looks similar to X. I can set the framebuffer to a
lower resolution (i.e. kernel=1024x768@60 in grub) and set X to 1024x768 with
xrandr to solve the problem.
I've also tried two different external LCD monitors on the VGA port with
success. Everything works correctly on the external monitors (even adding a
1280x800 modeline to them).
Both the nvidia and nv drivers detect the correct resolution and display it
correctly, so I've tried manually setting the modeline's that they use using
xrandr and nouveau, but the display stays distorted at 1280x800.
This isn't specific to the version included with Fedora 14. I've experienced
the same problem on the older versions of Nouveau included with Debian Squeeze,
Ubuntu 10.04 and 10.10.
