我有一台装有两块 PCI 电视卡的计算机。一块是 Compro（适用于 Win），另一块是 Leadtek（适用于 Linux）。现在，我正在尝试优化我的 Ubuntu 启动过程，我想禁用对 Compro 卡的检测，因为它在 Linux 上不起作用，它不会工作，即使它能工作，我也不在乎。有时，我使用的是...替代...操作系统，因此从机箱中取出 Compro 卡不是一个选择。有没有办法告诉 Linux“忽略放在那里（适当的 PCI 插槽）的任何硬件”？
我的有关电视卡检测的 dmesg 如下所示：

我知道，禁用该检测不会带来任何加速效果，但是这些行出现在 plymouth splash 之前，我不喜欢这样：\
答案1
为了防止加载模块，您可以将其列入黑名单。根据 dmesg 中的行，我猜应该调用负责的模块cx88xx。您可以通过检查 的输出来验证这一点lsmod | grep cx88xx。
将模块列入黑名单的过程如下：
- 创建文件
/etc/modprobe.d/blacklist-cx88xx.conf（文件名是随机选择的）。 插入：
blacklist cx88xx更新初始 ramdisk 以防止模块在启动时加载：
sudo update-initramfs -u- 下次重启后应该会立即显示更改。
