2. ubuntu cannot log on to the graphic interface

The profile file was modified during jdk configuration yesterday, so that the system cannot be accessed after the system is restarted (the user name and password are correct)

The cause is of course related to the changed environment variable file. You can delete the newly added error configuration.

Solution:

1. Ctrl + Alt + F1 login to ubuntu console mode,

2. Edit the configuration file/etc/profile. Direct vi/etc/profile is not acceptable. Because the environment variable file is damaged, you need to use the complete command line to call it, that is

/Usr/bin/sudo/usr/bin/vi/etc/profile
