Ubuntu: MS TrueType font install

At first add keyword multiverse to repositories list in /etc/apt/sources.list. Then download Tahoma font and execute:

$ sudo apt-get install msttcorefonts
$ cabextract IELPKTH.CAB
$ sudo cp *.ttf /usr/share/fonts/truetype/msttcorefonts/

Edit /etc/defoma/hints/msttcorefonts.hints file (as root) and append the following lines:

Actually these lines are taken from Arial font description and modified to Tahoma.

Then execute:

$ sudo defoma-font -v reregister-all /etc/defoma/hints/msttcorefonts.hints

Add the line bellow to /etc/X11/xorg.conf file:
FontPath "/usr/share/fonts/truetype/msttcorefonts"

May be helpful (may be not):

$ sudo dpkg-reconfigure defoma
$ sudo defoma-reconfigure
$ sudo fc-cache -f -v
