Font menus disabled after initial selection in Xterm's VT Fonts

PROBLEM DESCRIPTION or QUESTION


While running xterm for Linux, after using CTRL+Right Click to change the font size initially, the font size options will be greyed out and unselectable.


RESOLUTION


The proper fonts relevant to the menu are not provided by Xmanager. So Xterm thinks the menu is no longer available and disables them.
Changing the font size menu would not have worked because of this reason.
Try again after doing the following:
1. Edit the .Xdefaults file in the user's home directory. If it doesn't exist, you'll need to create it.
2. Insert the following into the file.
XTerm*VT100.utf8Fonts.font1:    nil2
XTerm*VT100.utf8Fonts.font2:    5x7
XTerm*VT100.utf8Fonts.font3:    6x10
XTerm*VT100.utf8Fonts.font4:    7x13
XTerm*VT100.utf8Fonts.font5:    9x15
XTerm*VT100.utf8Fonts.font6:    10x20
