Brak możliwości zalogowania się do systemu raspberry pi os na monitorze

[Mantoehutsyzp]

Witam,

Mam problem odnośnie zalogowania się do malinki gdy wpisuję poprawnie login i hasło (pi; raspberry) wyświetla się czarny ekran a później znowu wyświetla się ekran logowania.

Z góry bardzo dziękuję za pomoc.

@Mantoehutsyzp czy problem dotyczy tylko logowania przez interfejs graficzny? Czy te same dane pozwalają na zalogowanie się do RPi za pomocą SSH?

Tylko przez interfejs graficzny przez PuTTy działa

[Treker (Damian Szymański)]

@Mantoehutsyzp taki problem może powstawać, gdy na karcie pamięci jest zbyt mało miejsca. Czy jest to czysta instalacja systemu, czy to jakaś "stara" malinka, której karta może być już zapchana?

@Treker System jest dosyć nowy (1-2 miesiące) a to karta 64 GB więc nie powinno się chyba aż tak zapchać.

Na temat chybania to się nie wypowiem, ale do sprawdzania miejsca na karcie służy polecenie df, np:

df -h

pokaże wszystko w "ludzkich" jednostkach.

Dołącze sie do pytania. Dzisiaj przyszla mi malina pi zero W. Próbuje połączyć się przez VNC zeby miec interfejs graficzny i za grzyba nic. Odczytałem IP scannerem i za pomocą raspi-config włączyłem VNC i ciągle wywala mi błędem "Timed ot waiting for a response from the computer".  Przez putty łącze się bez problemu.

Dodam że mam pi zero 2W i tam bez problemu wszystko poszło jak jakiś czas temu robiłem.

@ethanak jest napisane, że zostało 41 GB pamięci

Czyli nie karta - jedna możliwość sprawdzona.

I nic...

Reinstalacja raczej nie pomoże bo będziesz miał to samo co miałeś wcześniej. Niestety, nie mam ani jednej malinki z interfejsem graficznym... ale sprawdź pliki w /etc/lightdm - może tam się coś namieszało?

@ethanak Tak wygląda drzewko tego folderu:

├── keys.conf
├── lightdm.conf
├── lightdm-gtk-greeter.conf
├── pi-greeter.conf
└── users.conf
