Hello to all. When ubuntu is loaded, an authorization window appears, a password is entered, and all is done. After entering the password, the authorization window disappears and the working environment should appear here, but instead the laptop makes a sound and throws it back to the authorization window. If I enter the wrong password, then it says that the "Invalid password." Through the guest also does not go. When I pass authorization through the console ( Ctrl+Alt+F1 ) then everything is fine, I can execute various commands.

Before that, I put this here, because the laptop was very humming (cooler), etc. But there is a plus, the laptop is no longer buzzing much, but I cannot work for it. People who know, help the newcomer) And then he was already tired)

When entering through any user all the same. That is, this is not due to user settings.

Ubuntu 16.04 Xenial Xerus. Unity.

Here is what is written in the .xsession-errors file after a failed login:

 openConnection: connect: No such file or directory cannot connect to brltty at :0 upstart: gnome-session (Unity) main process (2449) terminated with status 1 upstart: Disconnected from notified D-Bus bus upstart: logrotate main process (2314) killed by TERM signal upstart: update-notifier-crash (/var/crash/_usr_lib_colord_colord-sane.113.crash) main process (2354) killed by TERM signal upstart: update-notifier-crash (/var/crash/_usr_lib_x86_64-linux-gnu_indicator-application_indicator-application-service.1000.crash) main process (2355) killed by TERM signal upstart: bamfdaemon main process (2424) killed by TERM signal upstart: hud main process (2438) killed by TERM signal upstart: unity-panel-service main process (2456) killed by TERM signal upstart: job indicator-bluetooth failed to stop

After executing these commands here:

 sudo apt-get remove --purge xserver-xorg sudo apt-get autoremove sudo apt-get autoclean sudo apt-get clean sudo apt-get install xserver-xorg sudo dpkg-reconfigure xserver-xorg sudo reboot

After the reboot, the black screen and the underscore symbol blink in the upper left corner and that's it.

  • @alexanderbarakin is not. not duplicate. here throws back. and there was just a black screen) there was a problem with the screen (monitor). and here something else) - SkiesX
  • with a probability much greater than 50%, it is exactly the same: user settings scattered across files / directories within the home directory. it is checked elementary - by creating a new user and trying to log in on his behalf. - aleksandr barakin
  • @alexanderbarakin alright. if it had not yet come through my acc. why then through the guest is the same? - SkiesX
  • @alexanderbarakin when creating a new user is the same. Do not know how to solve this problem? - SkiesX
  • start by analyzing the errors in ~/.xsession-errors . delete this file, try to login again, and analyze it after that, paying the most attention to the last lines. - aleksandr barakin

Most likely the memory is not enough on the disk. See how much df left. I had it
You can also try under su

 mount -o remount, rw / Xorg configure cp /root/xorg.conf.new /etc/X11/xorg.conf sync reboot
  • one
    16% of memory is used. - SkiesX
  • but what you wrote second where there is Xorg , is this at the expense of memory? - SkiesX
  • @SkiesX No, this is a reconfiguration of X's - Herrgott
  • Through recovery mode->resume can go? - Herrgott
  • and how to get there? I'm new to all this ( - SkiesX

I had a similar problem. Nvidia video card, probably? If so, then this is the proprietary driver put unity. Go to Ctrl+Alt+F1 and type this:

 sudo dpkg --get-selections | grep nvidia

We delete the driver itself:

 sudo apt-get remove nvidia-xxx

where xxx is the version of your driver, which is install. Next, delete the update:

 sudo apt-get remove nvidia-current-updates reboot

Must earn.

PS After the tricks of Bumblebee and OpenGL, I moved to KDE from sin, because judging by the numerous reviews, Nvidia and Unity do not want to get along.

  • Yes, it's because of the video card, bumblebee wasn’t supported, it was necessary to install nvidia-prime - SkiesX
