I am generally using yelp (the life preserver icon on the desktop) to view system man pages. After I open yelp, I can press Ctrl+L and enter man:man for example to view the man page for the man command.
This works OK. However, the line width is different on each of my Ubuntu installations. For example, the first (physical) line of man man page's DESCRIPTION section in yelp is like this:
Ubuntu 18.04 LTS (Virtual Machine):
man is the system's manual pager. Each page argument given to man is normally the name of
Ubuntu 19.04 (Virtual Machine):
man is the system's manual pager. Each page argument given to man is normally the name of a program, utility or function. The manual page associated with each of these arguments is
Ubuntu 19.04 (Physical Machine):
man is the system's manual pager. Each page argument given to man is normally the name of a program, utility or function. The manual page associated with each of these arguments is then found and displayed. A section, if
As you see, in my desktop (physical machine) man pages are formatted very wide. You can view the page correctly only when the yelp window is maximized. However, when you set it to something half of the screen width, the lines are wrapped and the physical line breaks occur at odd places which is very confusing.
How, can I set yelp to display man pages with say 80-character physical lines?
Note: Setting the MANWIDTH environment variable, works in man command line; but, does not make any change in yelp. For example, the command MANWIDTH=80 yelp man:man still displays wide lines as described above.
