我在一台配有 2 个显卡的笔记本电脑上运行 Debian Jessie。我使用 Bumblebee 在显卡之间切换。optirun 命令初始化了一个新的 x 服务器，该服务器在速度更快但功耗更大的显卡上运行。
问题如下
我跑……
optirun vlc
或者
optirun vlc --intf qt4
或者
optirun vlc --intf qt4 --no-xlib
并且 vlc 无法加载 qt4 界面。vlc cli 和 ncurses 界面确实在 optirun 命令下运行，但功能不如 qt4 界面丰富且易于使用。您对这个问题的根源有什么看法？
Bumblebee 守护进程日志内容如下：

你试过了吗：optirun vlc --x11-display :8
