Created attachment 627119 [details]
/var/log/messages from boot to shutdown

Description of problem:

If laptop is booted with external VGA monitor connected, system hangs or crashes after login. Conversely, connecting the external monitor works fine *after* login.

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


How reproducible:

Steps to Reproduce:
1. Connect external monitor.
2. Power on, wait for boot
3. Login
Actual results:

varies, but typically external monitor is blank, laptop screen just displays
fedora background. Mouse moves (including off-screen into notional external
monitor area), but 'windows' activity button won't bring up gnome-shell,
and the system seems generally dead. Other times random lines have appeared on the screen. This particular time, ctl-alt-del successfully brought up the power-off dialogue.

Expected results:

The system to be usable with external monitor.

Additional info:

Note that if the system is booted without the external monitor, then the monitor is connected *after* login, it works fine, with the desktop spread
across the two screens.
Possibly related is the fact the laptop won't suspend while the external monitor is connected.
This system is 5 years old, and has worked fine with fedora 14 and earlier.

gen3 chips have 3d rendering limits that shell now tries harder to avoid.
