===== 문제점들 =====
==== 추가 드라이버 설치 GUI 작동 안함 ====
  * 21.10 최신 업그레이드에서는 잘 작동하는 듯함.
  * nvidia PC에서 추가드라이버 GUI 화면에서 nvidia 드라이버 설치가 안돼서 명령행으로 설치함.
  * [[linux:ubuntu:ubuntu_drivers|Ubuntu Drivers]]
  * [[linux:nvidia|Linux Nvidia Graphic Card]]
<code sh>
sudo ubuntu-drivers install
sudo reboot
</code>
  * nvidia/intel dual on-demand 모드에서 4K HDMI dual monitor 시에 화면 갱신 속도가 너무 느려서 ''prime-select nvidia''로 사용하고 있음.
