Description Jan Kratochvil 2011-11-10 11:27:15 UTC 
Description of problem:
This is X220 notebook with "Use this output" disabled for its "Laptop" output
in XFCE and using the "HDMI1" output instead (X220 has DP connector).

Version-Release number of selected component (if applicable):
xorg-x11-server-Xorg-1.11.2-1.fc16.x86_64
kernel-3.1.0-7.fc16.x86_64

How reproducible:
Always.

Steps to Reproduce:
Connect external display.
XFCE Settings->Display->Laptop->Use this output = OFF
XFCE Settings->Display->HDMI1->Use this output = keep at ON
Turn off the external monitor.
Turn on the external monitor.

Actual results:
Monitor displays text console with getty but it does not respond to anything.

Expected results:
Monitor displays live X session.

Additional info:
One can easily recover it by:
ctrl-alt-F2 - the cursor starts flashing, text console becomes alive.
alt-f1 - X session is displayed again and everything works there fine.
Sorry I have tested/running only XFCE.

There is in fact no active display that time.

3.1.0 was ages ago.  F16 updates currently has 3.4.9; is that any better?

Even if it's not, it'd help to see the output of intel_reg_dumper(1) from the working and broken states.
Comment 5 Jan Kratochvil 2012-09-20 10:46:31 UTC 
It really works now; I use the display different way now so I no longer face it.
That's great, this was a long-standling "Linux" desktop usability issue.
