Comment 169 for bug 1065400

I did this morning. unfortunately some strange side effect has completely
disabled the bluetooth. I dont even see the Ubuntu bluetooth item on the
wifi drop down menu at the upper right on the Gnome desktop. I have tried
everything to "enable" bluetooth but to no avail.

it seems the problem is now worse.

any ideas?

thanks
rich
