"Linux/ubuntu Learning 13" Ubuntu good PDF software Okular

Step 1: Installation

sudo apt-get install okular

Step 2: Notes

Press the F6 shortcut to open the Comment feature and you'll find it's amazing.

Step 3: Chinese configuration

If the Chinese display after the installation is a problem, you can try as follows, if there is no problem can be skipped.

Enter in the terminal.

sudo apt-get install poppler-data

If not yet, enter again

sudo apt-get install poppler-utils

If still not, it may be because some PDF files do not explicitly indicate the font, the system will default in English font to display, resulting in Chinese font display failed!

The solution is:

sudo vi/etc/fonts/conf.d/49-sansserif.conf

Put
<edit name= "Family" mode= "Append_last" >
<string>sans-serif</string>
</edit>

Switch
<edit name= "Family" mode= "Append_last" >
<string>monospace</string>
</edit>

If the modified font monospace still cannot be displayed, then you can change to the song body to display!
