Xorg.log showing no abnormalities. Default resolution should be 1366x768, but is not related to choppiness.
Description of problem:
X.org is choppy after upgrading from F11 to F12. This only occurs when "hybrid graphics" is set to use the Intel GPU, pointing to a problem in the Intel driver. Screen refreshes about 2 times a second. Top shows no abnormal CPU usage, terminal windows respond smoothly. Possibly a timing problem?
Hardware is an Asus UL50Vg, Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller.
Tried setting the AccelMethod to EXA or XAA without luck. Also tried the nomodeset kernel option.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. boot notebook
choppy, unusable, slow desktop experience.
Smooth and Shiny desktop experience

Created the attachments, althou I thought I already had an Xorg.0.log. This one is huge for no reason I can think of. I've attached a very interesting dmesg. There is no xorg.conf available in my original setup (althou ofcourse, I've tried several without luck), so I didn't attach one.
To elaborate on the choppiness: bringing up the login window takes about a minute after the Fedora logo is completed (eg. booting completed). Logging in goes quite fast this time, but the desktop takes another 3 minutes to appear after entering the password. And still then, everything (including mouse) is not-really-responsive. None of this happens when using "External Graphics" (nouveau). Bringing up the desktop takes no more than 20 seconds, and everything responds smoothly.
