I can make this happen very reliably on my mostly-Rawhide machine:

(1) Run a DVD in VLC.
(2) Pause the DVD.
(3) Close the lid (*note* my laptop is configured to *not* suspend).
(4) Open lid.

Consequences of this:

(1) VLC cannot play at all (even after restart).
(2) Terminal colours and messed up.
(3) Acceleration is disabled.

In xorg.log:

How do I enable debugfs to read that error state?

(as I said, "mostly" Rawhide, but lots of F16 packages still)

This also happened to me (or something similar) with F17. I don't know how exactly it happened. I locked the screen and when I unlocked it again, gnome-shell was down (it fell down about the time I unlocked the screen). This is tail of Xorg.0.log:

I recently updated my laptop to almost pure F17, and
the steps in comment 4 still cause this bug 100% reliably.

I have recently upgraded my desktop to fedora 17. I have observed that whenever I login after some time the my X crashes. 

On checking the Xorg.0.log I saw that I am getting similar error specified here.

Here is the log excrept - 

[  1065.491] (EE) intel(0): Detected a hung GPU, disabling acceleration.

I am attaching my hardware profile, i915_error_state from debugfs and dmesg.

I am seeing the same error after Fedora 18 upgrade:

Detected a hung GPU, disabling acceleration.

Right after start.

#rpm -qa kernel xorg-x11-server-Xorg xorg-x11-drv-intel
xorg-x11-drv-intel-2.20.16-1.fc18.i686

xorg-x11-server-Xorg-1.13.1-4.fc18.x86_64

My screen suddenly goes completely black and switching to virtual terminals or switching back doesn't change anything. I must restart the system. After a restart, I see the following in my Xorg.0.log.old:

[ 25693.349] (EE) intel(0): Detected a hung GPU, disabling acceleration.

I just hope that it is not a hardware problem!

The problem have not happened for me anymore, looks like that it is fixed in the updates.

This message is a reminder that Fedora 17 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 17. 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bug reports from releases that are no longer maintained.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 '17'.

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 17'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 17 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, you are encouraged  change the 
'version' to a later Fedora version prior to Fedora 17's end of life.

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.

Fedora 17 changed to end-of-life (EOL) status on 2013-07-30. Fedora 17 is 
no longer maintained, which means that it will not receive any further 
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of 
Fedora please feel free to reopen this bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.
