Estaba ejecutando Ubuntu 16.04 LTS con un controlador NVIDIA 361 instalado manualmente. Después de actualizar el controlador a v367, ahora estoy bloqueado de Unity con un ciclo de inicio de sesión con el siguiente error en .xsession-errors :
X Error of failed request: BadValue (integer parameter out of range for operation)
Major opcode of failed request: 154 (GLX)
Minor opcode of failed request: 3 (X_GLXCreateContext)
Value in failed request: 0x0
Serial number of failed request: 32
Current serial number in output stream: 33
openConnection: connect: No such file or directory
cannot connect to brltty at :0
También encontré esto en el Xorg registros:

Intenté degradar a v364 y luego volví a v361 sin éxito
Intenté purgar xserver-xorg, xserver-xorg-core, nvidia*, lightdm sin éxito
Intenté reinstalar ubuntu-desktop en vano
Un reformateo completo y una reinstalación serían muy perjudiciales y quiero evitarlo a toda costa.
El mensaje de error en .xsession-errors siempre sigue siendo el mismo. ¿Cómo puedo purgar/restaurar/restablecer mi configuración y/o paquetes y/o bibliotecas a un estado sano sin volver a formatear y reinstalar por completo?
Respuesta aceptada:
Agregar +iglx a xserver-command en /usr/share/lightdm/lightdm.conf.d/50-xserver-command.conf .
[SeatDefaults]
# Dump core
xserver-command=X -core +iglx
Después de lo cual reinicia o Ctrl-Alt-F1, inicia sesión y sudo service lightdm restart .
Funciona de maravilla
