He instalado Ubuntu 16.04 beta 2 el lunes 18 de abril. Cuando intento instalar nvidia-current, nvidia-361 o la versión que instala jockey, lightdm no se inicia por completo o no puedo pasar la ventana de inicio de sesión. Cuando inicio sesión, lightdm.log informa que he iniciado sesión correctamente, por algunas razones, muestra el volumen de sonido que he configurado y luego vuelve a la pantalla de inicio de sesión.

Tengo una computadora portátil con gráficos híbridos nVidia / Intel con tecnología Optimus (realmente no necesito el cambio de GPU, pero quiero que nVidia se ejecute correctamente), el modelo nVidia exacto es GT630M.

Aquí está Xorg.0.log:

Por ahora, estoy atascado con nouveau / intel, que a veces es bastante limitante. ¿Alguna idea de lo que puede estar pasando? Tal vez el archivo /etc/X11/xorg.conf faltante podría ser el problema, pero no sé por qué no está allí.

Nota: A partir de la versión principal de 16.04, el error cambió de no se detectaron dispositivos y no se encontraron pantallas a Error al inicializar la extensión GLX (no se encontró el controlador NVIDIA X compatible) . Ahora, lightdm comienza más fácil, pero todavía no puedo pasar la pantalla de inicio de sesión.

Edición adicional: tenía el arranque seguro desactivado todo el tiempo. He instalado bumblebee que agregó el controlador nvidia (probé 304 y 340), pero no pude iniciar programas usando la tarjeta de video nVidia. Una investigación posterior ha demostrado que el modprobe para nvidia estaba fallando debido a algo como esto:

could not insert 'nvidia': Unknown symbol in module, or unknown parameter (see dmesg)

Intenté una versión posterior del controlador (361), pero siguió fallando. Leí en alguna parte que los controladores i915 estaban causando este problema, pero no los tenía instalados.

Más información: Esta parece ser la causa raíz. Con el controlador nVidia instalado junto con su módulo DKMS, no pude insertarlo en el núcleo (usando modprobe). El error informado fue que no puede encontrar un puerto PCI específico (el que debería estar de acuerdo con lspci). No he guardado la redacción exacta, lo siento.

Gracias al esfuerzo colectivo de la comunidad, he logrado que funcione.

Primero, acceda a una Terminal (presionando ctrl- alt- f1si no puede iniciar sesión, o mediante el modo de recuperación). Instale los controladores nVidia versión 364 (paquete nvidia-364).

sudo apt-get install nvidia-364

Si no se encuentra el paquete, agregue el ppa que lo contiene:

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update

Reinicie su computadora.

sudo reboot -i NOW

Si no regresa a la pantalla de inicio de sesión, pero solo puede ver su fondo, fuerce a que vuelva a crear su configuración de usuario (guardar una copia de seguridad):

sudo mv ~/.config/dconf/user ~/.config/dconf/user.old

Luego, reinicie lightdm:

sudo service lightdm restart

Si desea instalar bumblebee, tenga en cuenta que su configuración estará mal configurada y buscará nvidia-current incluso si nvidia-current no está instalado. Lo he editado para referirme a nvidia-364 (porque los archivos instalados están en / usr / lib / nvidia-364) y pude iniciar programas con optirun.

Tuve algunos problemas con Nvidia y 16.04, finalmente lo puse a funcionar. en un nvidia gtx980m (computadora portátil para juegos asus G752): sugiero que se asegure de intentar instalar desde la línea de comandos y no simplemente habilitar los controladores propietarios de la gui ... (sigue leyendo)

No estoy recibiendo el bucle de arranque descrito, pero estaba obteniendo baja resolución (800x600) y no funcionaría en absoluto, pero el nuevo estaba bien. (Todo a través de la GUI del controlador)

Finalmente caí a la línea de comando e instalé el mismo paquete a través de "sudo apt-get install nvidia-xxx (en mi caso fue 361 - también probé 352)

luego se instaló normalmente, pero apareció un menú en el terminal que decía que el arranque seguro "UEFI" estaba habilitado y que tendría que ingresar una contraseña única para deshabilitarlo al reiniciar "para arrancar en modo inseguro. Así que hice eso .

Una vez hecho esto, al reiniciar, efectivamente apareció un menú de ventana UEFI y decidí cambiar el modo de inicio a inseguro. Luego me pidió varios caracteres "por posición" (por ejemplo, escriba el carácter 6, luego escriba el carácter 4, etc.) seguido de ingresar cada vez. Finalmente, después de 3-4 caracteres, me permitió desactivar el arranque seguro. Luego, la máquina se reinició nuevamente, y dijo "modo inseguro de arranque" y los controladores funcionaron.

También lo descubrí cuando instalé virtualbox también a través de synaptic, pero al menos funcionó y apareció un menú usando ese método ...

Espero que ayude...

¿Cómo recupero mi escritorio?

Pulsando ctrl- alt- f1desde la pantalla de inicio de sesión, se puede ir a una línea de comandos. Inicie sesión con su nombre de usuario y contraseña. Desde esta línea de comandos, puede desinstalar los controladores de nvidia ejecutando los siguientes comandos:

sudo apt remove nvidia-361
sudo apt autoremove

Tenga en cuenta que la versión específica de nvidia puede ser diferente. Puede encontrar la versión del controlador nvidia instalado ejecutandoapt search nvidia | grep installed | grep nvidia

o si solo desea cambiar a la tarjeta gráfica Intel sin quitar el controlador nvidia, ejecute

prime-select intel

¡Pero quiero usar mi tarjeta nvidia!

Hay algunas opciones que puedes probar:

Deshabilitar arranque seguro

Como dijo @biff, Secure Boot podría bloquear la carga del controlador nvidia. Para deshabilitar el arranque seguro, instale el controlador nvidia usando la línea de comandos . Ubuntu le pedirá que deshabilite el arranque seguro durante la instalación.

Instale el controlador nvidia anterior

Algunos problemas pueden solucionarse instalando el controlador nvidia anterior.

Tengo el mismo problema. Ejecutando Ubuntu 16.04. Intel HD4600 y Nvidia 765M. Intenté todas las sugerencias anteriores. Funcionó al instalar usando terminal, pero si uso varios monitores, se produce un error y termino en un bucle de arranque.

Leí a alguien sugiriendo que el controlador beta 364xx funciona.

En mi caso, solo instalar nvidia-364 resolvió el problema. Mi configuración es NVidia GTX 750Ti en ASUS H170 + Intel i7 6700 + 32Gb DDR4 con Ubuntu 16.04.

Tengo una GTX980 y no pude iniciar sesión después de la actualización a 16.04 (desde 15.10). Eliminar nvidia:

sudo apt-get purge nvidia*

e inició sesión. Funcionó pero la resolución se limitó a 800x600.

Los siguientes pasos resolvieron mi problema:

1. Vuelva a instalar nvidia: sudo apt-get install nvidia-361
2. Reiniciar, ir al BIOS y desactivar el arranque seguro

Gracias biff por el consejo para deshabilitar el arranque seguro :-)
