Thank you for taking the time to report this bug and helping to make
Ubuntu better. We are sorry that we do not always have the capacity to
look at all reported bugs in a timely manner.
This was reported against a very old release so I'm going to close it.
If you still have the issue please
This may be un-related but... if my external USB drive is connected I
get the same symptom (blank screen, flashing cursor).
To be clear, this hardware configuration worked perfectly until I
upgraded to Karmic.
Is there a log file?
