IPA fonts installation on Ubuntu 16.04

To compile Japanese document with xelatex, I decided to use IPA fonts.

  1. Download IPA font files files (*.ttf files) from here.
  2. Create a directory to save the font files as
    sudo mkdir /usr/share/fonts/truetype/ttf-ipa-font
  3. Copy the font files to the created directory as
    sudo cp *.ttf /usr/share/fonts/truetype/ttf-ipa-font

Beamer: Navigation bar jumps to wrong slide

I made some slides using Beamer, however I thought Beamer has a serious problem and therefore I gave up using it. The problem is navigation bar icon jumps to wrong slide, which is the next slide of the right one. Back to the problem again, I could find a solution to fix the problem, actually it’s not a problem at all.

Carefully looking at links in a generated pdf, the navigation bar icons specify the right slides and the wrong behavior is due to pdf viewer. Following a discussion, a solution is to set pdf viewer single-page mode. With this setting, all my Beamer slides behave as expected 🙂
