Ubuntu 13.04 – Wireless / Wi-Fi Not Working
These instructions are for Ubuntu 13.04 running the Unity Interface. They may be the same or similar for other versions, but no guarantee is made. There are a lot of reasons why your wireless / Wi-Fi connection is not working, but the most common is lack of a driver. A driver is a piece of software that allows the operating system to communicate with a piece of hardware (in this case, a wireless device). While Ubuntu (and other Linux distros, in general) provide good support for a wide variety of hardware devices, there are various reasons a particular device is not supported, but the 3 most common are: the device is newer and support is not provided in the default operating system. the device and the driver for the device is proprietary, in which case it … Read entire article »

Ubuntu 13.04 – VirtualBox Guest Additions Stop Working After Update
These instructions are for Ubuntu 13.04 using the Unity Desktop, running under VirtualBox 4.2.12. They may be the same or similar for other version combinations, but I make no guarantee. Sometimes, after installing updates, the VirtualBox Guest Additions stop working. To get them working again, it is necessary to reinstall them. 1) Open the Dash by tapping on the Windows / Super key: Note: tapping the Windows keys means pressing it as though you intend to type it. It does not mean holding down the key (holding down the key does something else). Ubuntu calls this the Super key 2) Type vboxadditions into the Dash query field: 3) Press Enter to open the VirtualBox Guest Additions Folder: Note: pressing the Enter key will select the first Dash entry. If VBOXADDITIONS is not the first entry, then use the keyboard … Read entire article »

3D Hardware Acceleration not Working in VirtualBox
Under certain conditions, I have observed that 3D hardware acceleration is not working in VirtualBox 4.2.12 when running Ubuntu 13.04. It may affect other VirtualBox versions, and it may affect other guest / host OS combinations. This problem does not affect Ubuntu 12.04 running as a guest OS. When the Problem has been Noticed VirtualBox is running on Windows 7 with SP1 the guest OS is Ubuntu 13.04 (32-bit) only a single CPU is configured for the virtual machine the underlying hardware is an AMD Quad-Core A6-3400M Resolving the Problem In my case, I have been able to solve the problem by configuring the virtual machine to have more than 1 CPU. Suspicions Initially, I thought the problem might be the VT-x/AMD-V or Nested Paging settings which are only enabled when multiple CPUs are configured for the virtual machine, but … Read entire article »

Ubuntu 12.10 – VirtualBox Guest Additions not Working
This applies to Ubuntu 12.10 running under VirtualBox version 4.1.22 (or earlier), 4.2.0, 4.2.2, and 4.2.4 under Windows 7 with Service Pack 1. The issue and solution is likely the same for all versions of VirtualBox 4.1.22 and 4.2.x, regardless of which OS they are running on. Unfortunately, the problem with VirtualBox 4.2.2, and 4.2.4 has no solution at the moment. This problem is resolved in VirtualBox 4.2.6 and later. Note: you will need to reinstall the VirtualBox Guest Additions. (the instructions are for Ubuntu 12.04, but the steps are the same) The Problem When you install VirtualBox Guest Additions under Ubuntu 12.10, you find that the video drivers don’t work properly: you get no 3D hardware acceleration and the display resolution is fixed at 1024×768 (or 800×600). If you are observant, when you install the VirtualBox … Read entire article »

Ubuntu 12.04 – GNOME Desktop Not Working – Looks like GNOME Classic
This is for the GNOME Desktop installed on Ubuntu 12.04 The problem and solution is likely the same for all other Linux distros, but no guarantee is made. One of the alternative desktops you can install is GNOME (or, more accurately, GNOME 3). Unfortunately, in some cases, instead of getting the new GNOME desktop: you get the old GNOME Classic (no effects) desktop: You can tell it uses no 3D hardware acceleration because the text in the toolbar is white. In the GNOME Classic interface (which does use 3D hardware acceleration), the text is greyed out: NOTE: This distinction is true when you are running Ubuntu 12.04 or have installed ubuntu-artwork on your system (ubuntu-artwork is automatically installed when you install Ubuntu 12.04). This distinction may not exist if you are running some other distro or are … Read entire article »

Fedora 16 – First Impressions – Not Positive
UPDATED 11-May-2012 I have discovered that the problem with Software Updates and Add/Remove Software noted below was caused by VirtualBox Guest Additions not being correctly installed. This happened because the Linux kernel header files are not installed, GCC (a compiler) is not installed, make (a tool for GCC) is not installed. Installing gcc and make was not a problem. Installing the Linux kernel header files was. For some reason, kernel-devel-3.1.0-7.fc16.i686.PAE is not available (I am sure if I hunt around some more, I will find it, but that is beside the point, I am interested in install, test, use not install and fiddle around until I get some semblance of a usable system. Notwithstanding the problems it has with VirtualBox Guest Additions, I still find it hard to like or recommend Fedora 16: (1) The Software and … Read entire article »

Ubuntu 12.04 – Virtualbox Guest Additions Stop Working after Update
These instructions are for Ubuntu 12.04, with the Unity interface, running under VirtualBox 4.1.12_77218. They should be the same or similar for other version combinations, but no guarantee is made. Sometimes, when Ubuntu updates are applied to your system, the VirtualBox Guest Additions stop working. Symptoms may include: (1) screen resolution reverts back to the default setting, (2) shared folders no longer work. Trying to fix it by selecting Install Guest Additions… does nothing (and it won’t because Guest Additions are already installed). The fix is to rerun the Guest Additions installation program. There are three ways to do this. Method 1 I think this is the easiest and fastest way. 1) Locate the VBOXADDITIONS disk icon (it is probably the only disk icon) located near the bottom of the Launcher (it is most likely just … Read entire article »
