在Linux系统中安装NVIDIA驱动时遇到与Nouveau驱动冲突的问题，导致安装失败。冲突原因是Nouveau内核驱动与NVIDIA驱动不兼容。解决方法包括禁用Nouveau驱动，如在Fedora、RHEL/CentOS等系统中创建黑名单配置文件并更新initramfs。在完成这些步骤后，可以尝试重新安装NVIDIA驱动。

报错原因：ERROR: The Nouveau kernel driver is currently in use by your system. This driver is incompatible with the NVIDIA driver, and must be disabled before proceeding.
问题现象：驱动安装失败，安装log文件提示说源码树未发现或者版本不匹配
解决办法：很大程度上我们安装的kernel-devel与kernel-headers与实际内核版本不匹配，这里指的是自动安装的情况;
查看核版本，

7.3. Disabling Nouveau
To install the Display Driver, the Nouveau drivers must first be disabled. Each distribution of Linux has a different method for disabling Nouveau.

The Nouveau drivers are loaded if the following command prints anything:

$ lsmod | grep nouveau

Fedora
Create a file at /usr/lib/modprobe.d/blacklist-nouveau.conf with the following contents:

blacklist nouveau
options nouveau modeset=0

Regenerate the kernel initramfs:
$ sudo dracut --force
Run the below command:
$ sudo grub2-mkconfig -o /boot/grub2/grub.cfg
Reboot the system.
7.3.2. RHEL/CentOS
Create a file at /etc/modprobe.d/blacklist-nouveau.conf with the following contents:
blacklist nouveau
options nouveau modeset=0
Regenerate the kernel initramfs:
$ sudo dracut --force
7.3.3. OpenSUSE
Create a file at /etc/modprobe.d/blacklist-nouveau.conf with the following contents:
blacklist nouveau
options nouveau modeset=0
Regenerate the kernel initrd:
$ sudo /sbin/mkinitrd
7.3.4. SLES
No actions to disable Nouveau are required as Nouveau is not installed on SLES.

7.3.5. WSL
No actions to disable Nouveau are required as Nouveau is not installed on WSL.

7.3.6. Ubuntu
Create a file at /etc/modprobe.d/blacklist-nouveau.conf with the following contents:
blacklist nouveau
options nouveau modeset=0
Regenerate the kernel initramfs:
$ sudo update-initramfs -u
7.3.7. Debian
Create a file at /etc/modprobe.d/blacklist-nouveau.conf with the following contents:
blacklist nouveau
options nouveau modeset=0
Regenerate the kernel initramfs:
$ sudo update-initramfs -u
