Thank you for taking the time to report this issue and helping to make
Ubuntu better. Examining the information you have given us, this does
not appear to be a bug report so we are closing it and converting it to
a question in the support tracker. We appreciate the difficulties you
are facing,
If you enter: xset -b into a terminal or Alt-F2, it will fix you problem
for the time you are logged in. For a longer term solution, add `xset
-b` to System - Preferences - Sessions.
