I'm new to Ubuntu. I have tried to install Ubuntu 13.10 in VirtualBox with Base OS Windows 7.  The Installation was fine and I did Tick on Download updates and Third Party App. After this it completed installation and Rebooted , Ubuntu load up to Just wallpaper and cursor on the screen. After some time It showed error :   “Sorry, Ubuntu 13.10 has experienced an internal error.” /usr/bin/compiz.   What to do now please.

I installed 13.04 as a virtual machine using VirtualBox from Oracle. When it was done doing the install, it says that it needs a reboot. After the reboot, I got this message:     Sorry Ubuntu 13.04 has experienced an internal error /usr/bin/compiz   I'm not sure what it means and how to resolve it.

Okay my question is that, I want to run a heavy application, on a Virtual Machine (VirtualBox) with just 2 GB RAM (Windows 7 32Bit Host has 4 GB, 3.5 GB effective). Initially I thought of installing Ubuntu Server 12.04.1, which doesn't come with a GUI, so I thought it would be efficient in performance, but I have only Ubuntu 12.04 Desktop.  My question is, is it possible to remove the GUI parts in Ubuntu 12.04 Desktop (Not Server), keeping only the core OS, after installation in a virtual machine?   Or, is there anyway to improve the performance of the OS?  If you need more information, I am ready to provide.  I don't want the GUI or anything, even a small terminal window is fine for me, I can access files through FTP.

I was using 13.04 as a guest OS on my VirtualBox 14.2.18. Host is Windows 8. After upgrade to 13.10 Ubuntu does not start. I can see a black screen and blinking cursor. I am pretty new to Ubuntu. I suspect a problem with graphics drivers. I can access tty and all files (/home) are there.

I had installed Ubuntu inside Windows XP but then I formatted XP and installed Windows 7.   EDIT1: I used Wubi for the same. I want to know which one of the two will solve my problem? creating a virtual disk or resizing root? Also is resizing root possible as the 4GB ext4 partition is already in a NTFS format Hard Drive partition.  At the time of installation I had allocated only 4GB of space to Ubuntu. I want to increase that size as I keep getting a low disk space notification.   I have surfed through a lot of similar questions but this is not a duplicate.  Because I want to know a little about the file systems. In order to solve my problem,do I have to increase the size of root.disk? Or will it be solved by creating a virtual disk?  Also I want to know the difference between creating a virtual disk and just increasing disk space of root.I'm new to Ubuntu so I don't know how the file systems function.  EDIT2:I have created a virtual disk of 10gb ,but I'm still getting the same notification.Is there anyway to install all further applications on the virtual disk I created?

Since upgrading to Ubuntu 14.04, When I launch my VirtualBox virtual machine I get:  Failed to open a session for the virtual machine win7pro32bit. Implementation of the USB 2.0 controller not found! Because the USB 2.0 controller state is part of the saved VM state, the VM cannot be  started. To fix this problem, either install the 'Oracle VM VirtualBox Extension Pack'  or disable USB 2.0 support in the VM settings (VERR_NOT_FOUND).  Result Code: NS_ERROR_FAILURE (0x80004005) Component: Console Interface: IConsole {8ab7c520-2442-4b66-8d74-4ff1e195d2b6}   The solution to the  does NOT fix the problem:  sudo apt-get purge virtualbox sudo apt-get autoremove sudo apt-get update sudo apt-get install virtualbox   UPDATE: Also happens when upgrading VirtualBox itself to 5.0, within existing Ubuntu 14.04.

Inside a VirtualBox VM, I have installed myself an Ubuntu 16.04.1 LTS Server installation. However, when I installed the ubuntu-desktop package and rebooted, this happened:    Exact command I used: sudo apt-get update; sudo apt-get install ubuntu-desktop ..and then a reboot command.  This just seems like a corrupted top-left portion of the screen, as my cursor can appear in view (but corrupted):    This is a purely graphical issue because I can use the keyboard to successfully progress to a desktop:    Note: On startup it shows correct graphics for a split-second then reverts to glitch.    Any help on this?

This is my first post on askubuntu. So, if i break any rules, then please do tell me.  I am using Windows 10, on a 4gb ram,64 bit environment. Previously when I used to install Ubuntu then I used to install it with wubi. So, I didn't have to make extra partitions or so. But,now as I came to know from some of the post on this forum that wubi is no longer available for installation of ubuntu. Is it even possible to install ubuntu 15.10 in the same way as wubi did, but manually, or any other software.  While using wubi, if ubuntu had problems, I could just simply uninstall ubuntu from the control panel. And nothing else. So, I don't want to make extra partition to install ubuntu.   Steps Tried: I installed ubuntu 13.10 using wubi. And then upgraded the ubuntu to latest version. After upgrade when it restarted, there was mounting problem,So again had to uninstall. Is there way to solve this mounting.   Any Help/Explaination would be nice.

How can I reinstall Ubuntu 13.04 safely, without losing anything except settings? Is it possible? Or at least keep only programs and the home directory?  I want to reinstall as I have recently experienced various issues like the scrolling being very jumpy and lightdm rendering weirdly. Can someone more experienced explain how to reinstall Ubuntu as I have been searching in vain for days. Thanks in advance.

I've followed this tutorial to install Ubuntu 15.10:    After restarting my computer I got to the grub menu and chose Ubuntu. Shortly after that I got this error:  /run/lvm/lvmetad.socket: connect failed: No such file or directory WARNING: Failed to connect to lvmetad. Falling back to internal scanning.   These messages keep adding up on a black screen every second. After a while,  I get access to the initramfs ash console.  what am I doing wrong?

I would like to install Ubuntu on my Windows 7 64-bit PC to do analysis of astronomy data. The data files are often large (can be few hundred MB, possibly a GB). The data files may be located on an external hard disk. The PC has 6 GB RAM and 670 GB hard disk.   I'm trying to decide whether to do a proper dual-boot, installing Ubuntu in its own partition (I'm nervous of messing around with the hard disk, have never done it before) or to run Ubuntu using VirtualBox in Windows. How much slower is running in Virtualbox likely to be?   If I do go for a traditional dual-boot, would it make sense to divide the hard disk more or less equally between the two OSs?  I would be very grateful for some advice.  Many thanks Kevin

I am running Ubuntu 12.04 in VirtualBox 4.2.6 on a Windows 7 host. After installing Ubuntu I wanted to get the VB interface in fullscreen. I therefore installed guest additions from Virtual Box Manager (devices > install guest additions -> run --> reboot).  But after booting I can only see a part of the desktop without menus. In addition I am asked again to install the guest additions after every reboot (the guest additions CD reappears even though I had removed it).  Editing the resolution in system settings via right click > appearance -> all settings (since I can only partially see the desktop) the actual resolution changes but the whole desktop still does not fit.  Do I have to uninstall/reinstall the guest additions? What other options do I have?

I'm a little confused as to whether I should install Ubuntu on its own partition on my hard drive, use VirtualBox or another virtualization package to install it, or use Wubi to install it directly on top of my current OS (Win 7). I definitely want to learn and use Ubuntu, so this is not just for playing around with it.   Also, if I choose to partition, should I partition the hard drive myself or should I let the Ubuntu installation menu do it for me? I understand that I am going to need a main partition, for Ubuntu's core components, and also a swap partition. Then there is the option to add a partition for "home"- I don't understand what combination of these partitioning options I should choose, or whether it is better to partition in Windows before I install Ubuntu or just partition my hard drive when I install Ubuntu itself

I have an ASUS K55VM and it came with DOS, and then Windows 7 was installed. I am planning to install Ubuntu on it. My computer had 4 partitions: 240GB, 230GB, 230GB, and 230GB, and I changed this to 5 partitions: 243GB, 230GB, 230GB, 150GB, and 80GB. I installed Ubuntu 12.04 to the 80GB partition through a USB flash drive. It installed fine, however the problem is during the Boot option in Windows Boot Manager. When I choose Ubuntu, this what is displayed:  Windows failed to start. A recent hardware or software change might be the cause. To fix the problem:   1. Insert your Windows installation disc and restart your computer.   2. Choose your language settings, and then click "Next,"   3. Click "Repair your computer." If you don't have this disc, contact your system administrator or computer manufacturer for assistance.    File: \ubuntu\winboot\wubildr.mbr   Status: 0xc000000e   Info: The selected entry could not be loaded because the application is missing or corrupt.   I tried to change the boot option for the OS and made Ubuntu as my first option. It worked, however Windows 7 does not show up in GRUB. In this fear I did the following:     Restarted my PC changed boot option 1 to Windows.   Formatted the drive to which Ubuntu was installed (80GB one) through Windows.   Restarted again.     The problem persists. Windows Boot Manager still shows Ubuntu, and when I choose this it gives two lines one like: grub rescue&gt;, but my Windows 7 is working perfectly fine.  Now I want a solution to remove Ubuntu from the Windows boot option and reinstall completely.

I need to install Ubuntu instead of Windows 7. Can you tell me the steps to do it? I don't want to install Ubuntu alongside Windows. Any precautions needed before installing Ubuntu? How do I install Ubuntu 11.10 without losing the current data in my laptop?

I have a Windows XP laptop, in which I run VirtualBox with the latest Ubuntu, my hardware is little old, so running the latest version of Ubuntu inside Virtual box is kind of a hassle, very slow performances, even if all i'm doing is running the terminal and practicing Linux commands !  I tried DSL (Damn Small Linux) with my VirtualBox, very small distro (50 MB), I am satisfied with how faster is my system now, but I miss Ubuntu, moreover, DSL is missing too many commands, such as sed an many others that I can't remember.  Is it possible to run Ubuntu just in console mode, no GUI or minimum GUI...no nice effects no fancy graphics? A link / tutorial would be much appreciated.

Is it possible to convert a Physical Ubuntu Install (Intel based PC with Ubuntu 10.10) to a virtual box disk, so that I can use that same environment on a separate pc or can keep it virtual for testing?  Something similar to "Disk2VHD" which converts a physical Windows 2K3 and above box into a VHD or VMware image.  Will be grateful for your assistance ! Kind Regards
