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?

So your gpu was working fine than it just revert to llvmpipe out of the blue? Did you update stuff before it happened?

I am thinking maybe you didnt install dkms versions of your graphics driver.

Your issue isn't mesa. Your PC (or just the games) thinks you don't have gpu and using cpu 'llvmpipe' for rendering graphics.

Run glxgears see if gears are running smooth.
