Hoy cuando comencé Ubuntu, no comenzó lightdm
, mostrando una pantalla en negro. Cambié a la consola Ctrl-Alt-F1 e intenté comenzar lightdm
manualmente
sudo start lightdm
Me arrojó a la consola gráfica (Ctrl-Alt-F7) y mostró la misma pantalla en negro. Además, parece que comienza, la consola devolvió el número de procesos,
lightdm start/running, process 3616
Sin embargo, después
sudo stop lightdm
tengo
stop: unknown instance
Entonces empecé gdm
sudo start gdm
Y gdm
comenzó normal. Entonces, el problema en lightdm
.
Para resolver el problema intenté purgarlo lightdm
y reinstalarlo
sudo apt-get purge lightdm
sudo apt-get install lightdm
y
sudo apt-get install --reinstall lightdm
Las dos formas no ayudaron.
Ahora lo uso gdm
, pero quiere restaurar lightdm
si es posible.
¡Gracias a todos por su ayuda!
PD: No instalé recientemente ningún controlador adicional (y no tengo ninguna tarjeta NVidia).
PPS: alguna información adicional
