我有一台 Acer Predator Helios 300 2019 笔记本电脑，具有 Xubuntu 18.04 和 Windows 双启动功能，我已经使用了 3 年多了。上周五，我的第二台 HDMI 显示器突然不工作了，所以我重新安装了 nvidia 驱动程序。我知道我的显示器可以工作，因为它可以显示在 Windows 上。最奇怪的是，有三次，它似乎启动得很快，两个显示器都工作正常，比如当我回滚到 nvidia 驱动程序 450 或当它以驱动程序 510 以紧急模式启动时（这样做了两次），但是当我关机或重启时，它会循环启动，启动非常慢，并且只检测到一个显示器，这又导致了同样的问题。如果我以恢复模式启动，然后恢复启动，则只有笔记本电脑显示器或外接显示器可以工作。我包含了 journalctl 错误消息。我已经束手无策了，请帮帮我。
我尝试了以下方法：
- fstab UUID 看起来不错
- 安全启动已禁用
- xubuntu 使用 lightdm 作为显示管理器
- 更新至最新的 Nvidia 驱动程序 (510) 然后重启
sudo apt-get remove --purge '^nvidia-.*'
sudo ubuntu-drivers autoinstall
sudo apt-get update
通过“附加驱动程序”选项卡回滚驱动程序然后重新启动，我已经尝试了 450、470，现在使用的是 510。
使用恢复驱动器（例如“fsck /dev/nvme0n1p6”）在我的主分区、交换分区和根分区上运行 fsck
编辑我的 /etc/default/grub 以包含以下内容然后 sudo update-grub
GRUB_CMDLINE_LINUX_DEFAULT="splash noresume nogpumanager nvidia-drm.modeset=1"
GRUB_GFXMODE=1920x1080
- xrandr 的结果（我的两个显示器都应该为 144hz）
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1920 x 1080, current 1920 x 1080, maximum 1920 x 1080

1920x1080 77.00*
- 我也尝试过解决方案启动时间缓慢
- systemctl --failed 的结果
