===== 문제점 =====
==== Clipboard 마지막 복사가 안 되는 현상 ====
  * ''Ctrl+C'' 로 복사 후 firefox 를 close 하면 복사 내용이 사라지는 현상이 발생한다고 함.
  * [[linux:parcellite|Parcellite]] 설치할 경우 문제 해결됨. -> 그렇지만 [[linux:wayland|Wayland]] 지원 안돼서 삭제
==== grub-customizer 설치 안됨 ====
  * [[linux:grub|Linux Grub]] ''grub-customizer'' 가 PPA 를 통해서도 설치 안됨. 그냥 설치 안하기로.

==== gnome / wayland / nvidia ====
  * [[https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/6146|Gnome 43: gnome-shell forces itself onto dGPU instead of using iGPU in PRIME Render Offloading setups using Wayland (#6146) · Issues · GNOME / gnome-shell · GitLab]]
  * nvidia + wayland 사용시 gnome-shell 이 아무리 nvidia 드라이버를 ''prime-select nvidia''로 해도 intel UHD GPU 를 사용하는 현상이 발생했음. (nvidia 3050)
  * **Gnome 설정 -> 정보** "그래픽" 항목 확인해보면 ''Intel UHD'' 로 나옴.
  * [[https://discussion.fedoraproject.org/t/wayland-setting-primary-gpu-nvidia/70762|Wayland setting primary gpu(NVIDIA) - Fedora Discussion]] <code sh>
glxinfo | egrep "OpenGL vendor|OpenGL renderer"
# 아래 결과가 나옴
OpenGL vendor string: Intel
OpenGL renderer string: Mesa Intel(R) UHD Graphics (TGL GT1)
</code>

  * 이로 인해서 **4K** 모니터 사용이 불가능한 상황. -> X11 로 전환함.
  * 아래 참고해보면 가능할 듯. 원래가 nvidia + wayland 는 잘 안되는 것인가 봄.

==== firefox 안열림 ====
  * [[linux:flatpak|Flatpak]]으로 설치한 firefox 사용시 다른 애플리케이션들에서 링크가 안 열리는 현상이 발생함.
  * **설정 -> 기본앱** 에서 보면 두개의 firefox 가 보여서 다른 걸로 바꿔줬더니 잘 작동함. 아마도 x11 firefox, wayland firefox 두개로 나뉘어 있는게 아닌가 의심됨. -> 결론적으로는 ''firefox'' deb 패키지와 flatpak 패키지가 둘 다 설치돼 있었기 때문임. **deb 패키지를 삭제하면 된다**

<code sh>
sudo apt remove firefox
