How to set monospace font with .emacs shared between ubuntu and Cygwin

How to set monospace font with .emacs shared between ubuntu and Cygwin

[KARR, DAVID]

I have Cygwin emacs 29.4 running on my Windows laptop.  I have an Ubuntu VM running on that laptop, which is running Emacs 27.1.  I am trying to use the same .emacs file through a shared folder.  For most things, this works perfectly fine.  My Cygwin Emacs is using a proper monospace font, but the VM is using a proportional font.  I'd prefer that they both used the same font, but at a minimum, the Ubuntu VM needs to use a monospace font.

In my Cygwin Emacs, I ran "list-fonts" and got this:
-----------------
Fontset: -*-*-*-*-*-*-*-*-*-*-*-*-fontset-default
Fontset: -*-courier new-normal-r-*-*-13-*-*-*-c-*-fontset-standard
Fontset: -outline-Courier New-regular-normal-normal-mono-13-*-*-*-c-*-fontset-startup
-----------------

In my Ubuntu VM Emacs, I did the same and got this:
-------------
Fontset: -DAMA-Ubuntu-normal-normal-normal-*-17-*-*-*-*-0-fontset-auto1
Fontset: -DAMA-Ubuntu-normal-normal-normal-*-13-*-*-*-*-0-fontset-auto2
Fontset: -*-*-*-*-*-*-*-*-*-*-*-*-fontset-default
Fontset: -*-fixed-medium-r-normal-*-16-*-*-*-*-*-fontset-standard
Fontset: -DAMA-Ubuntu Mono-normal-normal-normal-*-17-*-*-*-m-0-fontset-startup
--------------

My .emacs currently has no customization related to fonts, except for "(global-font-lock-mode 1)" (I don't even remember what that does, and the associated descriptions are circular).

What are my options here?

My suggestion is to have your .emacs file specify the default font for
Ubuntu, using the system-type variable as the dispatch.  Find a font
on Ubuntu that you like, and then add to .emacs something like

  (unless (memq system-type '(cygwin windows-nt))
    (add-to-list 'default-frame-alist
      '(font . "YOUR-PREFERRED-FONT-HERE")))

To find out the correct specification of YOUR-PREFERRED-FONT-HERE,
start Emacs on Ubuntu, try different fonts (including sizes) until you
find one that you like, and then type "M-: (face-font 'default) RET".
This should produce the font string you can use in the above.

To try different fonts, you can use S-mouse-1, then select "Change
Buffer font" from the popup menu, which will display a font selection
dialog.  Alternatively, Options->"Set Default Font" from the menu bar
will show a similar font selection dialog.
