Ubuntu installed some updates, and after the restart, I cannot log in. It seems to accept, but then beeps and returns to the login screen. All of the users, including guest do the same thing.

I was looking at some other posts here, and tried some of the suggestions without success. I looked at the .xsession-errors file but I don't understand the error:

X Error of failed request:  BadValue (integer parameter out of range for operation)
  Major opcode of failed request:  155 (GLX)

  • So to follow up and close this thread out... The authority edits and folder permissions did not help, I still could not log in. I also tried updating the nvidia drivers, and removing them via 'sudo nvidia-settings --uninstall' but that did not help either. What finally did work was totally removing the nvidia drivers 'sudo apt-get purge nvidia-*' and a restart. Thanks to @jargonjunkie for the right commands that worked. – David Nov 26 '16 at 14:46

Set appropriate ownership to .Xauthority and .ICEauthority.

chown username:username .Xauthority
chown username:username .ICEauthority

Set permission for /tmp

sudo chmod a+wt /tmp

Restart lightdm

dpkg-reconfigure lightdm
sudo service lightdm restart

Reboot and login, this should fix your problem, if not then remove incompatible graphics driver:

For Nvidia:

sudo nvidia-settings --uninstall 
sudo apt-get remove --purge nvidia*

For amd:

sudo apt-get purge fglrx*
