오늘 저는 데스크탑을 열었고 보기 흉한 저해상도 디스플레이를 만났습니다. 설정을 확인하면 이제 1024 x 768 또는 800 x 600의 두 가지 옵션만 사용할 수 있습니다.
이전에는 약 20가지 옵션이 있었는데 저는 1920 x 일부를 사용하고 있었습니다.
저는 POP!OS 20.04 LTS를 실행하고 있습니다.
/var/log/apt/history.log를 확인하고 다음을 발견했습니다.
Start-Date: 2021-03-28 09:43:04
Commandline: apt-get --allow-downgrades -y install pop-upgrade libpop-upgrade-gtk
Upgrade: libpop-upgrade-gtk:amd64 (0.1.1~1608137131~20.04~d3bfb98, 0.1.1~1616430952~20.04~7df32bb), pop-upgrade:amd64 (0.1.1~1608137131~20.04~d3bfb98, 0.1.1~1616430952~20.04~7df32bb)
End-Date: 2021-03-28 09:43:08
시도 $ sudo apt-get --allow-downgrades --reinstall install pop-upgrade libpop-upgrade-gtk하고 다시 시작했지만 도움이 되지 않았습니다.
나도 그랬다:
sudo apt clean
sudo apt update -m
sudo dpkg --configure -a
sudo apt install -f
sudo apt dist-upgrade
sudo apt autoremove --purge --remove --purge

아이디어가 부족해요. 어떤 도움이라도 대단히 감사하겠습니다.
고쳐 쓰다
"derpmatt"님 덕분에chat.pop-os.org누가 나한테 지적했지이 솔루션이제 로그인 문제가 해결되었습니다. 하지만 여전히 다른 사용자의 로그인을 수정(각 사용자로 로그인하지 않고)하고 여전히 4살짜리 로그인처럼 보이는 로그인 화면을 수정하는 방법을 찾고 있습니다!
다른 많은 게시물에서 제안한 대로 ~/.config/monitors.xml파일을 에 복사 /var/lib/gdm3/.config하고 소유자를 으로 변경해 보았지만 gdm이것이 내 컴퓨터에 아무런 영향을 미치지 않았습니다.
미리 감사드립니다.
