I'm running Redhat RHEL6.1 on my W520 which I have hooked up to an external monitor via a docking station.
Problem is that when I undock and close the lid I get a black-screen when reopening the lid. My only option at that point seems to be to do a hard power-down and reboot.
I've taken to completly shutting down my machine before undocking but it I'm sure there must be a way to get this working.
Has anyone else seen this problem?

I too have encountered this issue. Furthermore I've discovered that if I boot RedHat while undocked and later dock that I must be prepared for the W520 to completely lock up at some point. It could be minutes or hours later. To avoid this I've taken to the haibt of rebooting any time I wish to dock or undock the machine. This isn't really an acceptable way to conduct business but seems necessary for now.
