Nota il riferimento systemd-logind e a problemi di permessi, poi segue il crash.
Il dmesg invece apparentemente non da errori: la scheda sembra che venga correttamente attivata:

Quindi: perché Xorg da quell'errore? Mi sta venendo un grosso dubbio: ma non è che col tuo hardware dobbiamo usare l'altro approccio e non bumblebee?
Riassumendo:
il tuo user appartiene al gruppo bumblebee? Si? Sulla tty1 tu fai il login solo con questo utente e non con altri - tipo root: giusto?
Bene prova questo allora: aggiungi i moduli "i915 bbswitch" all'initramfs, rigenera l'initrrd, riavvia e prova a vedere che succede. Se non va, rimuovi i moduli, rigenera ancora l'initramfs e valutiamo il da farsi.
Nel frattemo reincolla il tuo ~/.xinitrc
