如果我输入lspci| grep VGA终端，我会得到这个输出：
00:02.0 VGA compatible controller: Intel Corporation Ivy Bridge Graphics Controller(rev 09)
01:00.0 VGA compatible controller: NVIDIA Corporation Device 0fd1 (rev a1)
当我安装 nvidia-current 时，它会安装 259.49，这是 650m 的错误驱动程序（259.59 是正确的）。有什么想法吗？
编辑：我使用了这个dpkg --list | egrep '(nvidia|bumbl)' | grep ^ii输出的命令
