Who this is for:
New users who have burned / booted dCore for the first time.
Depending on how the graphics drivers handle your monitor, you may find yourself in full-resolution, where with modern monitors things may just be a bit *too* small. Like my 1920x1080 native res monitor.
Dcore looks just fine, but for initial setup, the terminal fonts may just be a tad too small, leading to mistakes with dashes and underscores when you edit configuration text files if you are not careful.
The instant fix - and you don't even have to be online:
Dcore provides 3 terminals you can use
aterm
uxterm
xterm
They are configured to taste in your hidden .Xdefaults file. But if you aren't already knowledgeable on how to configure those, like which ones support only bitmap fonts vs true-type fonts, let's get up and running with some larg(er) fonts right off the bat.
From either of the 3 terminal choices, lets force xterm to use the default TTF font by supplying it with a faulty fontname!
xterm -fa bigterm &
There is no font titled "bigterm"! But called improperly like this, it will use a larger TTF font.
Now at least you may be able to avoid common errors like with underscores and dashes. Turn that command into an executable shell script if you like until you learn how to properly configure your desired terminal.
Of course one can go online and get what they like. This is just a solution for an out-of-the-box experience with the stock install.
Want to go just a bit further?
Make it look a bit nicer by adding some xft options in your hidden .Xdefaults file. By convention, we use a CAPITAL X at the beginning of the line.
Xft.antialias: true
Xft.hinting: true
Xft.hintstyle: hintfull
Xft.lcdfilter: lcdlegacy
Xft.rgba: rgb
You can look up what all these options do and apply different values to your liking. This will at least demonstrate how good a terminal inside a stock install of dCore can look.
