Post install of LMDE

The input method. LMDE is really fantastic.
-- ibus --
But you will find there is no other input method  installed by default. For me, ibus is the most fav. So just type
apt-get install ibus im-config
(this is used to replace im-switch). Then add input libraries that you like.
For example:
apt-get install ibus-pinyin
After this run ibus-setup, then simply restart

-- innotop --
Try to start innotop to monitor my kid MySQL.  Following error message show up:

Can’t locate Term/ReadKey.pm in @INC (@INC contains ….

To solve this problem type following commands with root privilege. 

perl -MCPAN -e shell
install Term::ReadKey
exit


-- search engine --
This is the most easiest way to fix it.
