Messed up root permissions Ubuntu 14.04 [duplicate]

  • 772

While changing a directory ownership, accidentally I did

sudo chown subhadip / instead of sudo chown MyApp

After realizing my mistake, tried to fixed few permissions i.e., sudo etc. by sudo chown -R root / stopped operation as its wrong.

Now I am getting “The system is running in low-graphics mode” error, which I believe because of wrong permissions only.

I am able to login in console mode.

Please guide me.

    To repair your personal space, run:

    $ sudo chown -R $USER:$USER ~/

    For any of the other applications that are broken you will have to repair them as you see a problem with an app. Most of the sysem files are owned by root and most will still work.

    Certain services such as Mysql and Apache are owned by a specific user... in the case of Mysql the user is mysql. In the case of Apache the default user is www-data.

    There are other server programs you might run such as Ftp. The Ftp server default user is ftp.

    If an application is broken, it'll most likely give an error that suggests a problem with permission.
