Ciao a tutti, eccomi di nuovo (abbiate pazienza!) questa volta non riesco a configurare la stampante, ho abilitato cups ma non mi permette di aggiungere la stampante, mi dice che non sono autorizzato e di immettere passwd e utente root. Grazie.

Come la stai configurando la stampante? Da localhost:631 o dalle impostazione del tuo DE?

E non ti esce nessuna mascherina per mettere la password? Hai provato direttamente nel browser?

L'utente normale dovrebbe fare parte del gruppo "lp" per poter utilizzare la stampante
Code:
# gpasswd -a <nome-utente> lp



Per abilitare l'utente normale a gestire le stampanti , esso dovrebbe far parte del gruppo "lpadmin"
Code:
# gpasswd -a <nome-utente> lpadmin


PS : Anche dall'interfaccia di cups è possibile gestire i permessi di stampa.

Fatto come mi hai detto, ma quando cerco di aggiungere la stampante mi dice che non sono autorizzato e dovrei mettere psw e nome utente, ma non vi è alcuna maschera per fare ciò.

Non dovrebbe venire fuori anche lp e lpadmin?

Niente da fare, ho provato in tutti i modi ma non c'è verso di configurare la stampante: non sono autorizzato e non posso immettere nome utente e passwd.

Sembra un problema più complicato delle mie capacità, mi tocca rimandarti al wiki: Printing

Controlla la configurazione del file di cups (/etc/cups/cupsd.conf) e riavvia il servizio dopo le modifiche, per essere sicuro che vengano recepite.

@MassimoG

Aggiungendo un gruppo o utente ad un grupponon è necessario riavviare. Basta il login ad una shell/terminale


#Aenigma
A questo punto credo sia fondamentale (doveva esserlo fin dall'inizio) un
Code:
# emerge --info


per avere più dettagli

Controlla il Wiki indicato da Xdarma per esser sicuro che non manchi qualche pezzo (PS : il servizio "cupsd" è abiltato/avviato ? )

Altra cosa : ricorda che l'utente "root" ha i permessi su tutto , quindi vedere se è abilitato alla stampa è poco influente a meno che non si forzi l'impostazione del SUID per tale servizio.

Magari abilita la USE lprng-compat solo per cups e abilita, secondo me globalmente, la USE python.
Se abiliti python globalmente sarebbe bene rigenerare tutti i pacchetti con tale USE con: emerge -DNv @world.

Poi, magari in un noioso giorno di pioggia, disabilita systemd globalmente attraverso il mascheramento del pacchetto: Gentoo Without systemd

Nel reinstallare cups mi sono accorto di questi due avvisi:
Code:
Could not find a Makefile in the kernel source directory.
 * Please ensure that /usr/src/linux points to a complete set of Linux sources


Andando poi nel manuale, mi consiglia di lanciare make menuconfig per configurare il kernel nel caso genkernel avesse tralasciato qualcosa nel settare le stampanti. Come dovrei fare esattamente?

/usr/src/linux è un link alla directory con i sorgenti, nel mio caso:
Code:
ichigo ~ # ls -lh /usr/src/
totale 4,0K
lrwxrwxrwx 1 root root   23 13 mar 18.19 linux -> linux-4.1.12-gentoo
drwxr-xr-x 1 root root 1,6K 17 mag  2018 linux-4.1.12-gentoo
drwxr-xr-x 1 root root 1,1K 13 mar 18.34 linux-4.19.27-gentoo-r1


Per creare o modificare il link puoi usare eselect. Per esempio:
Code:
ichigo ~ # eselect kernel list
Available kernel symlink targets:
  [1]   linux-4.1.12-gentoo *
  [2]   linux-4.19.27-gentoo-r1
ichigo ~ # eselect kernel set 2
ichigo ~ # eselect kernel list
Available kernel symlink targets:
  [1]   linux-4.1.12-gentoo
  [2]   linux-4.19.27-gentoo-r1 *
