Ubuntu 12.04 appears "Could not write Bytes:broken pipe" causes and solutions

New employees need to install the ubuntu12.04 and Android 5.0 compilation environment.

Its own operations have run over apt-get-y update and upgrade.

I installed the Gdm,dpkg-reconfigure GDM, selected GDM. The default is LIGHTGDM.

After restarting, there are problems with the same error.

To solve this problem, from the Internet search scheme (put to the last), does not work, the middle change back to the LIGHTGDM login. Method of Adoption:

Apt-get-y Remove xserver-xorg

Apt-get-y Install xserver-xorg

You will then find that you cannot log in with your user name, but you can log in with root and guest. Change back to the GDM login and find that you can log in.
