You didn't install the metapackage nvidia-legacy-340xx-driver, did you?

And the glx alternative still points to mesa:

which effectively disables the nvidia driver.

I cannot reproduce this by just installing
xserver-xorg-video-nvidia-legacy-340xx (without Recommends)
in a minimal buster chroot - the glx alternative is nvidia as it should
be.

You should undo all manual filesystem manipulations
(moving nvidia_drv.so, creating Xorg.conf, ...) and purge all nvidia
packages. Thereafter install nvidia-legacy-340xx-driver again.
