Thx for your answer but i can get full screen in GUI version but not in minimal installation (terminal version) see screenshut

console/terminal mode doesn't really know about pixels or screen resolution.

There are three ways (probably more) to make the screen bigger.

1.
export COLUMNS=XXX
if you want 120 characters for example... export COLUMNS=120

2.
add this to your .bashrc file.

# check the window size after each command and, if necessary,
# update the values of LINES and COLUMNS.
shopt -s checkwinsize

Every time you manually resize your terminal, it will notify the terminal.

3.
If you don't want to make this automatic, you can achieve the same effect by...
> sudo resize

But you will have to type this, everytime you resize your terminal window.

====================================

Virtual box has it's own screen settings, separate from your VM.

Change the "Scale factor" to 150% or 200% or whatever makes sense.

Finally when you have the virtualBox terminal window open....

Click on where it says "View" above, you will get several different window sizing options.

The other option (what I do most of the time)
Is just use something like PuTTY and ssh to your VM.
Then you don't have to worry about any of the options above.
