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 여기에서 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. 여기를 참고하여 드라이버 설치하면 다행히 문제 없다.

sudo apt install module-assistant build-essential dkms
sudo m-a prepare
git clone https://github.com/tomaspinho/rtl8821ce
cd rtl8821ce
sudo ./dkms-install.sh

이후 간헐적으로 AP 연결이 제대로 되지 않을 때는 'PCIe Activate State Power Management' 항목을 참고하면 된다. 아래처럼 /etc/default/grub파일에서 GRUB_CMDLINE_LINUX_DEFAULT에 'pci=noaer'을 추가한다.

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=noaer"

그리고 sudo update-grub으로 마무리하고 재부팅한다. 만일 이래도 동작하지 않는다면 와이파이 모듈을 강제로 초기화시키는 다음 스크립트를 동작시키는 방법도 있다. https://gist.github.com/chwnam/fb5a9006087dc2a0c745e2ba62cef1f6

한글 입력

님프를 사용하면 된다.

wget -O - http://apt.hamonikr.org/hamonikr.key | sudo apt-key add -
sudo bash -c "echo 'deb https://apt.hamonikr.org jin main upstream' > /etc/apt/sources.list.d/hamonikr-jin.list"
sudo bash -c "echo 'deb-src https://apt.hamonikr.org jin main upstream' >> /etc/apt/sources.list.d/hamonikr-jin.list"

sudo apt-get update
sudo apt install nimf nimf-libhangul

만약 일본어, 중국어 등 다른언어를 사용하고 싶은경우에는 다음과 같이 추가 패키지를 설치해줍니다.
sudo apt install libnimf1 nimf nimf-anthy nimf-dev nimf-libhangul nimf-m17n nimf-rime

im-config -n nimf

님프의 개발이 중단되고, 하모니카 팀으로 포크되었다. 빌드해서 사용하면 된다.

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.) Launchpad 버그 이슈에서 해당 글을 확인했고 #20 코멘트로부터 해결 방법을 얻었다.

/etc/default/grub 에서 GRUB_CMDLINE_LINUX_DEFAULT 항목에 iommu=soft를 추가한다.

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash iommu=soft"

sudo update-grub을 잊지 말자.
