gvim looks terrible on my RedHat. Unable to change font

Question

When running gvim on my RedHat:

Linux trex-06 3.10.0-514.el7.x86_64 #1 SMP Wed Oct 19 11:24:13 EDT 2016 x86_64 x86_64 x86_64 GNU/Linux

The spacing between letters is too wide which looks really bad.

I tried changing font (:set guifont=*) to monospace, and it stays exactly the same. Same goes for other fonts.

Any idea how to fix it?

Answer 1

As it turns out the fonts that

:set guifont=*

show are not installed.

No idea why gvim decides to show them. Might be a bug.

Also the suggestion here doesn't work. I believe that the font suggested is also not installed.

So a friend found:

:set guifont=Courier\ 10\ Pitch\ 13

Which works.
