我有一个问题，Plymouth 启动主题从不显示。默认主题和自定义安装的主题都不显示。
我尝试安装自定义主题并执行以下命令：
sudo update-alternatives -config default.plymouth
sudo update-initramfs -u
dmidecode输出

我的 GPU：Geforce 750
我也已quiet splash启用。
当我启动 Ubuntu 实时环境时，我只看到过一次启动屏幕。这不仅发生在 Ubuntu 上，也发生在其他发行版中。
问题可能出在 bios 还是其他地方？
编辑：切换到 nouveau 驱动程序后，启动画面重新出现。
问题仍未解决。
