I searched everywhere but not able to fix my problem. Can someone please help me?
Here are the details
I have Ubuntu 14.04 LTS as host OS.
I installed Oracle VirtualBox on it
Then I installed CentOS 6.6 as guest OS inside VirtualBox.
I was using it daily with no issues. Suddenly one day I saw a message that "Configuration defaults for gnome power manager has not been installed correctly", then I get login screen and after login nothing is displayed inside the VM window.
I used the gparted-live-0.22.0-2-i586.iso to go to its command prompt and there I used fdisk /dev/sda command to resize the partition.
Even after that I am not able to resolve the GNOME error and not able to login to centos inside virtualbox.
Can someone please help? Let me know if you need additional information.
At login prompt, press Ctrl-Alt-F2, this brings you to tty2, a text window. (You can try Ctrl-Alt-F1 to satisify your curiosity).
Login as root user.
yum remove gnome-power-manager
yum install gnome-power-manager
reboot
I tried it on my system it works. One more thing, while installing gnome-power-manager if it shows some error regarding space issues just free some space for this installation

I have an Ubuntu 20.04 'VMWare Workstation 16' Virtual Machine on an Ubuntu 20.04 laptop. When I try boot my VM, I see this output:
SMBus Host Controller not enabled!
Assuming drive cache: write through
/dev/sda5: clean 519701/1933312 files, 7505521/7732480 blocks
Failed to start Load AppArmor profiles
Failed to start Load AppArmor profiles managed internally by snapd
The VM then crashes and does not boot, immediately after the last message above. The first message is also new.
I don't think that I can access the terminal in the VM before the VM crashes. So not sure how I can fix this?
I have information in the VM that I'd like to access.

When launching the VM, try pressing shift when the VMWare logo comes to enter the manual setup.
After pressing F2, select 'Advanced Options for Ubuntu' and boot in recovery mode. When offered a list of options about what to do, go onto the root terminal. Enter sudo apt purge snapd and add blacklist i2c-piix4 to the bottom of the file /etc/modprobe.d/blacklist.conf
Then resume the boot and both are resolved.

I have a Vbox server running Centos 6.5 32bit, and I have it set as a dev server for some web apps I'm working on.
Guest Additions was working fine until there were some updates in the CentOS system. Upon reboot, guest additions does not work. The disc shows on the desktop, and I choose auto run when it comes up, but all it does is have a window popup and disappear very clickly (within the blink of an eye), and thats it. No error messages.
When I choose "Install Guest Additions CD Image" from the VBox tool bar I get the following image:
Where might I find a solution to this problem. I will be glad to find whatever info needed in the system, but not sure where to go. I have tried a couple of possible solutions from web searches, but so far I've had no success
this resolved it. manual install

I've just installed Arch Linux and installed the gnome package (Note: Not gnome-extra)
I open Gnome using the xinit gnome-session command, as I have already installed X Window.
When I run that command, Gnome opens up and I'm presented with a white terminal titled "login". However, nothing I do in this terminal actually does anything. No commands work, nothing.
Could someone help me figure out what I'm doing wrong? There have been a few questions around similar to this, however none that have been properly answered.
Thank you!
After installing gnome session you need to append
exec gnome-sssion
at the end of your .xinitrc file located at your home.
when you get the login: prompt enter your username and then your password.
Once you're logged in type startx to start gnome session
Solved! I hadn't set Gnome to startup automatically, so when you login to Arch Linux using your standard root login. Check that gnome is installed and works (Use: xinit gnome-session).
Create an account by going to Settings, Users, Create the account as Administrator. Logout of Gnome Log back in as root to your Arch Linux CLI Use the command: systemctl enable gdm The next time you reboot, you should be presented with the Gnome Login screen.

Installed Mint on a brand new Lenovo Z585 Ideapad alongside the pre-installed Windows 8. Everything seemed to go fine, until the reboot, which simply dumped me at a Grub prompt.
I tried the usual ls investigations, but my Mint partition (/dev/sda9) returns an error along the lines of "invalid file name ''." - sorry I can't be more precise right now.
I've booted back into the LiveCD and run boot-repair, which generated the following summary - http://paste2.org/Owy3XNpH.
os-prober recognises my Windows installs (the real install and the recovery thinger), but no Mint.
As far as I can see, browsing the partition through the live cd, the install itself is fine, but I'm more than willing to be corrected. Can anyone help?
Adding the answer in case others have this problem.
Turns out that SecureBoot was in the Security section of the Bios, and not in the Boot section, where I was looking for it.
Disabling it and running boot-repair fixed the problem.
No boot loader is installed in the MBR of /dev/sda

I am trying to install ubuntu 14.04.2 LTE. I have a lunovo ideapad with windows 8. I have followed all necessary steps flawlessly, and even factory reset my laptop to make this smoother. I get this error when trying to boot and install ubuntu. I also get it if i try to run ubuntu without installing. Also I tried re-downloading ubuntu, and remounting on my usb with the universal usb installer.
Is this error due to my computer, or the ubs/unbuntu? There was another option in the boot menu. It was check disk for error. I do not know if it was checking disk as in the iso disk or my hard drive, but a ubuntu lunch screen appeared and it was looking into some ubuntu files (on the usb), when it was done it said there was 2 errors. It did not say what kind or if it repaired it , or how to repair it. It only gave me the option to exit, then lunovo boot screen appeared and it stayed in a attempting to repair loop for quite a awhile so I gave up on that and shut down.
I would ask this in ask ubuntu, but I do not have enough "respect points" to upload an image.
Major respect to anyone who can help me out, I have been to get ubuntu for 2 days now, and I hit a dead end.
This error message can appears in those cases:
1. Your hardware it not compatible, usually ACPI issue. Try to boot with additional options: "noapic" and/or "acpi=off". You should be able to set parameters in "Other options" [F6 key].
2. Your RAM is broken. Check it in "Test memory" option.
