systemctl disattivato alcuni servizi

Buona giornata a tutta la comunità
In partenza il sistema è molto lento, per velocizzarlo ho disattivato alcuni servizi il risultato è stato pessimo il sistema non riparte più. Si blocca al login invece del nome utente ho una schermata nera il cursore che lampeggia e un rettangolo grigio del mouse.
Non volevo reinstallare il tutto come posso fare?

Ciao quando arrivi al login prova a cliccare alt+f2 o f3 , metti user e password . entri è dai il comando :

#systemctl --failed

guarda quelli che falliscono , è li abiliti con :

#systemctl enable ( nome servizio )

esci quando hai finito è riavvia , ricordati i comandi devono essere eseguiti con i permessi root :slight_smile:

niente da tastiera non riesco a dare nessun comando

Bene , scarica una immagine net install , di fedora falla partire in modalità rescue , segui i passaggi , fino al chroot , dopo che sei entrato nell’ambiente , ricontrolla ancora , dovrebbe farti accedere senza problemi al propt , è esegui gli stessi passaggi , in teoria hai disabilitato gdm è qualche servizio dipendente da esso. :slight_smile:

ho scaricato l’immagine net install sono entrato ma quando do i comandi del pos 2 mi da il seguente messaggio
Running in chroot, ignoring request
in che modo posso vedere i servizi attivati? e quali sono quelli essenziali per farlo partire

hai dato il comando scritto che ti propene il dvd ?

Con :

#systemctl

ti elenca i servizi attivi però sono quelli della live (errore mio) per avere una mappa dei servizi necessari sarebbe da creare un file .txt però il problema che se non riesci a entrare da console . è un pò più faticoso , dovresti operare cosi senpre che si riesce a entrare , quando ti appare la schermata di grub premi c , è dove vedi la riga rhgb quiet , dopo quiet scrivi init 3 , premi ctrl+x entri nel runlevel 3 , ti appare la console pura , entri e provi con :

systemctl --failed

ovvio non da dvd , se non hai tolto qualche servizio fondamentale dovrebbe funzionare , abiliti quelli falliti , poi dopo il riavvio se si arriva al loging sistemiamo gli altri , e che dio cè la mandi buona :slight_smile:

così mi ha fatto entrare
con

systemctl --failed

non mi da nessun errore
0 loaded units listed

prova a dare :

systemctl status gdm

allora fallisce quando entra x11 , o wayland , utilizzi nvidia ?
comunque vedi una schermata simile a questa ?

non fare caso al modulo , che è inattivo .

Per darti una idea dei moduli ti posto il mio :

LOAD   = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB    = The low-level unit activation state, values depend on unit type.

193 loaded units listed. Pass --all to see loaded but inactive units, too.
To show all installed unit files use 'systemctl list-unit-files'.

il tuo potrebbe essere leggermente differente però il concetto è quelsto :slight_smile:

si la scheda grafica è una Nvidia quadro K410
non proprio

*gdm.service - GNOME Display Manager Loaded: loaded (usr/lib/systemd/system/gdm.service; enabled; vendorpresent: enabled) Active: inactive (dead)

Difatti non parte prova a farlo partire manualmente con :

systemctl enable gdm e systemctl start gdm

akmods è attivo ? guarda con il cell il post se non hai un’altro pc è controlla che siano attivi i servizi che ho , calcola che in init 3 il gdm non dovrebbe partire perchè il runlevel 3 non lo permette però vediamo che errore dà altra cosa che mi viene in mente è usi nouveau o nvidia 340 come driver

Altra curiosità il file custom.conf è così ?

cat /etc/gdm/custom.conf
# GDM configuration storage

[daemon]
# Uncomment the line below to force the login screen to use Xorg
WaylandEnable=false

[security]

[xdmcp]

[chooser]

[debug]
# Uncomment the line below to turn on debugging
#Enable=true

deve essere uguale a questo

Buongiorno
l file custom.conf è uguale a quello del pos 13
mentre quando do il comando

systemctl start gdm

lo schermo diventa tutto nero e devo riavviare il sistema

Si è normale perchè sei in init 3 , hai guardato i servizi che ti ho postato se ti viene in mente quelli che hai disattivato ? perchè se gdm è attivo dovrebbe entrare senza problemi. :slight_smile:
