"The default configuration of GNOME power manager is not correctly installed. Please contact the Administrator"

Today, I helped my classmates download a WINE QQ In Ubuntu. As a result, the startup failed continuously after the installation. After the restart, the logon interface is abnormal. The prompt & ldquo in the upper right corner shows that the default configuration of GNOME power manager is not correctly installed, contact the administrator ;. I don't know what's going on at first. I searched the internet to find out why the disk space in the partition is insufficient.

Today, I helped my classmates download a WINE QQ In Ubuntu. As a result, the startup failed continuously after the installation. After the restart, the logon interface encountered an exception. The prompt in the upper right corner prompted "the default configuration of GNOME power manager is not correctly installed, contact the administrator ". I don't know what's going on at first. I searched the internet to find out why the disk space in the partition is insufficient.

The solution is as follows:

On the abnormal logon interface, users outside the root user cannot log on. At this time, the root user is logged on directly. After logging on to the system, you will be prompted that the file system has insufficient partition space. There are three options: Clear the recycle bin, check, and ignore. At this time, you can first clear the recycle bin.

Open the terminal and enter df-h.

Disk Partitions with insufficient disk space are generally caused by insufficient/directory partition space. Because a friend's/home has a partition and A/directory with 10 Gb space, the size is enough. I opened the Software Center and looked at it. Dizzy. I installed so many Development Kits. No wonder ~~

You must delete some software and delete those that are not commonly used. In the upper left corner, click application, Ubuntu Software Center, select installed software from the list on the left, and delete the less commonly used software. However, do not delete any errors ~~

At this time, you can log on normally after restarting.

In addition, when installing the system, the/home usually requires sufficient space (Personal PC), and The/directory is about 10 Gb old, if you install any software in your home directory, the/directory is relatively safe.
