Comment 54 for bug 1177333

Thank you to all the guys that responded to this very quickly.

I just want to say that I am also experiencing the same issue - my monitor is connected via DisplayPort. It's a Dell U3011 - connecting to an NVidia GeForce GTX680.

When I turn it off via the power button, and then switch it back on. I must switch to a different TTY (CTRL+ALT+F#) and then back to TTY7 (CTRL+ALT+F7) - whereupon I am greeted by a bug/crash handler window saying kdeinit4 has crashed.

For information, here is some data on my setup. If you want any more info or logs or anything, just ask please! =)
