CentOS guest in virtualbox failed to load GNOME Power manager

I've searched everywhere but couldn't fix my problem. Can someone please help me?

Here are the details

  • I have Ubuntu 14.04 LTS as host system.
  • I have installed Oracle VirtualBox on it
  • Then I installed CentOS 6.6 as a guest OS inside VirtualBox.

I have used it daily with no problem. All of a sudden one day I saw a message that "The default configuration for gnome power manager is not set correctly", then I get a login screen and after logging into the VM window nothing is displayed.

I used gparted-live-0.22.0-2-i586.iso to go to its command line, and there I used fdisk / dev / sda to resize the partition.

Even after that, I cannot resolve the GNOME error and cannot login to centos inside virtualbox.

Can anyone please help? Let me know if you need more information.

  • In the login window, press Ctrl-Alt-F2, this will bring up tty2, a text window. (You can try Ctrl-Alt-F1 to satisfy your curiosity).

  • Log in as root user.

    yum uninstall gnome-power-manager
    yum install gnome-power-manager
    reboot



I tried this on my system, it works. One more thing, when installing gnome-power-manager, if it shows some error in space issues, it just makes space for that installation
