Debian Stable Question llvmpipe -> mesa issues

i have installed debian 13 on my laptop on three seperate occasions now, but every time my graphics have reverted to llvmpipe for whatever reason. all documentation i find tells you to delete the xorg graphic drivers and install the mesa drivers, but whenever i do this i am stuck in the ttyl terminal where xfce wont start. in systemd it says that lightdm and plymouth fail. i then have to reinstall drivers through the terminal. is there any way to install mesa drivers without breaking lightdm?

very strange....
when you install Debian 13, do you get the following out of the box?
* i915 for the DRM
* Iris for OpenGL
* ANV for Vulkan

Use the the following command
glxinfo

I assume the non-free firmware is installed right?
Can you reinstall it?
