엔비디아 510.54를 사용해 보세요. 액세스할 수 있는 경우 다른 비디오 카드를 사용해 보십시오.

syslog 소음을 조용하게 하려면 다음을 수행하십시오.

sudo -H gedit /etc/default/grub# 이 파일을 편집합니다

찾다:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

다음으로 변경하세요.

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=noaer"

파일을 저장합니다.

sudo update-grub# GRUB 업데이트

reboot# 컴퓨터를 재부팅

업데이트 #1:

ASPM을 꺼서 해결됨: pcie_aspm=off
