我在运行 Mint 的 Nvidia Optimus 笔记本电脑上遇到持续的屏幕撕裂问题（但我也尝试过其他所有发行版），并且通常推荐的解决方案对我不起作用。我有一个外接显示器，通常与内置笔记本电脑显示器一起使用。
nvidia-smi 输出：

第一个常用的解决方案 - 打开 PRIME 同步
user@mint:~$ sudo cat /sys/module/nvidia_drm/parameters/modeset
[sudo] password for user:
Y
我这样做了，但屏幕仍然撕裂。
第二个常用的解决方案 - 力合成管道
这确实有效，但我一生都无法弄清楚如何让它坚持下去。如果我进入“NVIDIA X 设置”，我可以启用“强制合成管道”或“强制完整合成管道”；两者的工作原理似乎相同，但当我重新启动时该选项被禁用。如果我尝试将配置保存到 X 配置文件，则会导致内置监视器被禁用。我尝试使用以下命令并将其设置为在启动时执行：
nvidia-settings --assign CurrentMetaMode="nvidia-auto-select +0+0 { ForceFullCompositionPipeline = On }"
它也确实有效（不会禁用内置显示器），但它会重置我的显示配置。我可以手动修复它，但这在每次重新启动时都会很烦人。
据我了解，我需要修改命令以适应内置显示，但即使在阅读了我能找到的文档（例如 ArchWiki）后，我也不知道如何做到这一点。
我也得到这个输出：
user@mint:~$ nvidia-settings --query CurrentMetaMode
Attribute 'CurrentMetaMode' (mint:0.0): id=50, switchable=no,
source=RandR :: DPY-0: nvidia-auto-select @1920x1080 +1920+0
{ViewPortIn=1920x1080, ViewPortOut=1920x1080+0+0,
ForceCompositionPipeline=On, ForceFullCompositionPipeline=On}
有谁知道从这里去哪里？
