I encountered a login loop after updating xenial beta to the latest updates.

I tried a lot of things:

  • xauthority or /tmp privileges change

  • Reinstalling nvidia drivers, removing them.

  • reinstalling unity, unity-greeter, ubuntu-desktop, upstart, lightdm and compiz.

  • resetting compiz and unity settings.(I get dbus launch errors:

    Failed to commit changes to dconf: error spawning command line 'dbus-launch -auto launch=..................)

  • using older kernel and failsafe (failsafe report no screen found)

  • tried to launch other DE (steam big picture)

Here's xsession errors log:

unity:
open connection: connect: No such file or directory
Cannot connect to brltty at :0
upstart: gnome-session (unity) main process (5441) terminated with status 1
upstart unity-settings-daemon main process (5434) killed by TERM signal

steam big picture:
open connection: connect: No such file or directory
Cannot connect to brltty at :0

In Unity (compiz) log there are a lot of errors about opengl plugin

Compiz (opengl) - Fatal: glXQueryExtenisonsString is NULL for screen 0

And a lot of plugins unloaded because of opengl.

Lightdm have sudden SIGTERM signal with no prior errors in the log.

xserver have 2 errors:

xf86EnablePorts: failed to set IOPL for I/O (Operation not permitted)
(EE) Failed to initialize GLX extension (Compatible NVIDIA X driver not found)

But it continue through input operations until it suddenly get terminated.
