The previous question I posted was closed since I was advised that it was a bug, not a help issue.
That problem was that upgrading from (working) 11.10 to 12.04 (unusable) on my lenovo Y560 has left me with no mouse. The mouse arrow stays frozen in the middle of the screen. No USB devices are recognized at all. There is no internet connection.
So, the problem I am having here is that for the life of me I can't figure out how to report this as a bug, since I can't get any bug-report information out of my lenovo. I can run the suggested "ubuntu-bug xorg", but then I'm stuck because there's no internet, and I can't even hand-copy the information in the "Send problem report to developers?" window because I can't use the mouse to open the drop-down entries, or scroll the window.
Meanwhile, I can't get any help on the problem either because the thread has been closed.
Is there a way to report this bug? How?
