How to solve problems caused by. dmrc and. ICEauthority File Permissions

How to solve the problems caused by the. dmrc and. ICEauthority File permissions-Linux general technology-Linux technology and application information, the following is a detailed description. In order to describe such problems in a more specific way and help linux friends solve the problem, I have to explain the problem in detail!

1. $ HOME /. dmrc has been ignored. this will not save the default session and language, the file should be owned by the user, and the permission is set to 644. the user's $ HOME directory should be owned by the user, and other users cannot write.

Solution:
First, check whether the users and groups in the/home/directory belong to the root user. The directory must belong to the root user and root group.

# Ls-l/home/User Name
Drwxr-xr-x 4 root 4096 home

If not, change the group to root and the user to root.
# Sudo chgrp-R root/home // change the group to root
# Sudo chown-R root/home // change the user to root

Second, the permission for changing the/home directory is 755.
# Sudo chmod 755/home

Again, change the/home/user name/. dmrc permission to 644.
# Sudo chmod 644/home/user name/. dmrc

OK!

2. GNOME session management cannot be performed on files '/home/user name /. ICEauthority 'lock. please report this GNOME software defect. this error occurs when the file directory cannot be written. you can log on to the secure mode and make sure the directory is writable.

Solution:
First, check whether the users and groups in the/home/directory belong to the root user. The directory must belong to the root user and root group.

# Ls-l/home/User Name
Drwxr-xr-x 4 root 4096 home

If not, change the group to root and the user to root.
# Sudo chgrp-R root/home // change the group to root
# Sudo chown-R root/home // change the user to root

Second, the permission for changing the/home directory is 755.
# Sudo chmod 755/home

Again, change the/home/user name/. dmrc permission to 644.
# Sudo chmod 600/home/user name/. ICEauthority

OK!

Summary: Most of the reasons for the above two problems are for beginners to save trouble. In general, the full/home directory permission is usually revoked and 777 permissions are usually granted. This is a bad habit, because there are many hidden important files in the/home directory that we don't know yet, the problem is sometimes unpredictable, so we must be cautious when releasing permissions in Linux.
