我添加了 nVidia 显卡，现在无法完全删除英特尔集成驱动程序。尝试删除它们需要删除大量软件包，其中一些软件包非常重要（例如 Qt5）。有没有办法解决这个问题，而不必完全重新安装操作系统？
剩余英特尔软件包列表：
dzenan@corista:/etc/apt$ dpkg --get-selections | grep intel
libdrm-intel1:amd64 install
libdrm-intel1:i386 install
尝试安装涉及 OpenGL 的包：
dzenan@corista:/etc/apt$ sudo apt install libcairo2-dev

如何从软件包管理系统中删除有关此软件包和其他软件包的英特尔版本的信息？英特尔提供了许多与图形相关的软件包的自己的版本。
aptitude 的建议显示了软件包统计信息：
dzenan@corista:/etc/apt$ sudo aptitude remove libdrm-intel1
