==== 특이 사항 ====
=== 하드웨어 가속 ===
리눅스 민트 20에 와서 아래 내용은 의미 없어졌다.
2019년 6월 28일 현재 리눅스 민트 19.1 시나몬 데스크탑 환경에서 하드웨어 가속이 제대로 되지 않는 문제가 있다. 이것은 [[https://forums.linuxmint.com/viewtopic.php?t=293577|여기]]에서 언급된 것처럼 커널을 5.0대 버전으로 바꾼 다음
sudo add-apt-repository ppa:oibaf/graphics-drivers
sudo apt update
sudo apt upgrade
와 같이 처리하면 해결된다.
2019년 8월 4일 현재 리눅스 민트 19.2 시나몬 데스크탑에서는 커널만 5.0 대 버전만 올려줘도 하드웨어 가속은 올바르게 된다.
굳이 위 PPA를 추가할 필요가 없어 보인다. 사용해 본 결과 위 PPA는 너무 업데이트가 잦아 귀찮다는 단점도 컸다.
=== 무선 네트워크 ===
위 덤프에서 참고할 수 있듯 무선 네트워크 칩으로 R8821을 사용한다.
이제는 드라이버가 잡힌다. 굳이 아래 내용을 할 필요가 없다. 다만 기록을 위해 남겨둔다.
이것도 드라이버가 포함되지 않아 직접 잡아 줘야 한다. [[https://ubuntuforums.org/showthread.php?t=2398917&s=bb77298f3b6e13f9476912af22d58273&p=13793296#post13793296|여기]]를 참고하여 드라이버 설치하면 다행히 문제 없다.

이후 간헐적으로 AP 연결이 제대로 되지 않을 때는 [[|'PCIe Activate State Power Management']] 항목을 참고하면 된다. 아래처럼 ''/etc/default/grub''파일에서 ''GRUB_CMDLINE_LINUX_DEFAULT''에 'pci=noaer'을 추가한다.
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=noaer"
그리고 ''sudo update-grub''으로 마무리하고 재부팅한다.
만일 이래도 동작하지 않는다면 와이파이 모듈을 강제로 초기화시키는 다음 스크립트를 동작시키는 방법도 있다.

=== 전원 어댑터 연결해야 제대로 부팅이 되는 문제 ===
레노보 S340 전반에 일어나는 문제로 보인다. AMD GPU 관련 문제인 것 같다.
대개 전원 어댑터를 연결해야 제대로 부팅이 되는 문제가 발생한다. (가끔은 연결 안해도 될 때가 있다.)
[[https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1870971|Launchpad 버그 이슈]]에서 해당 글을 확인했고 [[https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1870971/comments/20|#20 코멘트]]로부터 해결 방법을 얻었다.
''/etc/default/grub'' 에서 ''GRUB_CMDLINE_LINUX_DEFAULT'' 항목에 ''iommu=soft''를 추가한다.
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash iommu=soft"
''sudo update-grub''을 잊지 말자.
