Re-attach uniquely
--------------------
If you are attached to a remote screen over SSH and the connection drops, then
you re-attach later with ``screen -x``, there will still be some pseudo-zombie
sessions attached. This is annoying because the new sessions will have their
display dimensions locked to the dimensions of the old sessions. To connect to
a screen session as the only client (disconnecting all the old half-dead
sessions), use:
$ screen -d -r
Disable default bash completions
---------------------------------
At least on debian wheezy, screen has tab completions which prevent, eg:
$ screen /dev/ttyU<TAB>
from completing as ``/dev/ttyUSB0`` et al.
To disable this, go to ``/usr/share/bash-completion/completions`` and ``sudo mv
screen screen.disabled``.
