[+0.02s] DEBUG: DisplayServer x-2: Can't launch X server Xephyr, not found in path [+0.02s] DEBUG: DisplayServer x-2: X server stopped[/quote]
Lightdm próbuje odpalić Xephyr zamiast standardowego Xorga.
Dziwnie to wygląda. W jaki dokładnie sposób instalowałeś i konfigurowałeś system?
Masz /usr/bin/X i /usr/bin/Xorg?
Można by było ustawić za pomocą opcji:# xserver-command = X server command to run (can also contain arguments e.g. X -special-option)[/quote]
Pokaż co masz w /etc/lightdm/lightdm.conf[/quote]
Mam stary laptop - Lenovo R60e, procesor Intel Core Duo T2300, 3GB RAM, SSD 120 GB. System instalowałem zwyczajnie - ściągnąłem ISO Debiana 9 poprzez torrent (https://cdimage.debian.org/debian-cd/current/i386/bt-dvd/), wypaliłem na DVD. Potem programem GParted 0.28.1-1.i686 zmniejszyłem partycję z Win 10 o około 43GB. Ustawiłem bootowanie z DVD i kilkałem "Continue" :-) Wybrałem język angielski i polską klawiaturę, ale to chyba nie problem? Gdy instalowałem system Debian 9 po raz drugi, w opcji środowisk graficznych do instalacji wybrałem pierwszą opcję ("Default Debian graphic environment"), "Xfce" oraz "standard system utils", ale to nic nie pomogło na okienko logowania. W trakcie drugiej instalacji na pendrive dodałem sterowniki od WiFi (iwlwifi-3945-1.ucode, iwlwifi-3945-2.ucode) dzięki czemu miałem poprawną godzinę w systemie :-)
Przedtem (na starym dysku HDD) miałem Windows XP i Debiana 8, którego instalowałem też z płyty DVD i nie było problemów. SSD chyba nie robi różnicy na minus?Kod:

[b]Zapomniałem napisać że masz zatrzymać lightdm[/b] "DisplayServer x-2", ale dlaczego na trzecim się próbuje uruchomić.
Przed zatrzymaniem pokaż:
ps -e | grep X
Zatrzymaj lightdm:
# systemctl stop lightdm.service
I sprawdź czy xserver jest zatrzymany:
ps -e | grep X
Potem:
# lightdm --test-mode --debug
I pokaż:
# cat /var/log/lightdm/lightdm.log
Jak uruchomisz przez startx to też pokaż:
ps -e | grep X

ps po startx

Musiałem uruchomić startx z konsoli tty2 bo na tty1 wisi mi zawartość loga.
Mam nadzieję że o to chodziło.

Tak o to chodziło. Tylko czasu mało bo ja zaczynam urlop i nad ranem wyjeżdżam. Na wakacjach komputera dotykam tylko okazjonalnie, ale jak nikt ci nie pomoże to postaram się odpisywać tylko nie wiem z jaką częstotliwością to będzie.
Dlaczego masz dwie sesje graficzne uruchomione, ustaw domyślne.
# systemctl isolate default.target
Możesz restartować lightdm.
# systemctl restart lightdm.service
I sprawdzić czy jest jeden.
ps -e | grep X
Zrestartuj komputer i pokaż swoje nie root-a

Już wiem na czym polega problem z brakiem ekranu logowania. Z uwagi na to że ekran mojego laptopa ma bardzo małą rozdzielczość (1024x768), mam podpięty przez D-Sub zewnętrzny monitor. Wczoraj coś mnie tknęło i odłączyłem zewnętrzny monitor i ekran logowania pojawił się bez zająknięcia.
Niestety nie wiem jak skonfigurować oba monitory, żeby ekran logowania pojawiał się na którymkolwiek z nich, a po zalogowaniu żeby był aktywny monitor zewnętrzny. Próbowałem wszystkich czterech opcji dostępnych w okienku które pojawia się po naciśnięciu Fn+F7 (zmiana monitora), ale to nic nie pomaga.

Zmodyfikowałem skrypt z linku z instrukcją xrandr:
#!/bin/bash intern=LVDS1 extern=VGA1 if xrandr | grep "$extern disconnected"; then xrandr --output "$extern" --off --output "$intern" --auto else xrandr --output "$intern" --off --output "$extern" --auto fi
Sam skrypt, zapisany w pliku, działa ok. W które miejsce, w który plik muszę go wkleić aby uruchamiał się automatycznie?
