Hi icaria36,
Your configuration boots to nouveau instead of the nvidia driver when
you boot into -lowlatency. As seen in the below Xserver logs:

Later on, when all your services are shutting down, it tries to modprobe the
nvidia driver, but its missing. Is it installed for the -lowlatency variant, or
just -generic only? Maybe check to see if it was built correctly in dkms logs.

Make sure your nvidia driver is built for your lowlatency kernel and
maybe try blacklisting nouveau.

couple of years, no problems.
