Nvidia graphics card cannot be used after manually building

Hello everyone, when I manually compiled the kernel and loaded the modules and then completed the compilation, the xorg configuration seemed to be invalid when starting. I can only delete it and start kde.

When I deleted the nvidia configuration, a new problem appeared. Is it because my kernel is not configured correctly?
this is my kernel .config:
https://0x0.st/XHk4.txt

dmesg:
https://bpa.st/YOPQ
My last nvidia configuration file was generated using nvidia-xconfig --prime, but when I generated it again this time, X11 could not start normally. This is the last xorg configuration file (I made a backup)：（6.8.7）

Since I cannot install the nvidia driver now, I cannot generate the configuration file

At present, I have recompiled the kernel but I don’t know if it will work. I executed make and make modules_install
and make install

Did you boot the kernel you compiled? What does

Code: Select all

lsmod | grep nvidia

and

Code: Select all

uanme -a

say?
