리눅스 서버(Linux Server)를 설치하고 Command-Line을 봤는데,
해상도가 너무 낮게 나오거나 비정상적으로 표시되는 사항이 있다면 아래 과정을 수행해보자.

$ sudo vi /etc/default/grub


위 명령어를 입력 후 많은 내용들 중 "GRUB_CMDLINE_LINUX" 사항을 다음과 같이 수정하면된다.

GRUB_CMDLINE_LINUX="vga=0x0368"


설정을 저장하고 아래 명령어를 한번더 입력한다.

$ sudo update-grub


vga 뒤에 나오는 HEX 값은 아래 해상도에 맞춰 넣으면 된다.
