Comment 11 for bug 487185

I have same situation, bu unfortunately I have problems too.
I have port replicator with connected external monitor.
So this monitor is not detected or just disappears on some random bases. After a while it can be detected again.
Display preferences, Detect monitor - nothing happens (i.e. changes).
Reboot typically helps.
I have Fujitsu Siemens Lifebook.

As from logs, I didn't find anything not listed here.
