VirtualBox black screen for Black Lab Enterprise Linux

Some of our users have been plagued by the VirtualBox black screen.  During the bootup and install of the Live image everything works as it should but after reboot you get a Black Screen when the X server is supposed to start.  While we are working on a fix for this issue, here is a work around that will start the X server and give you full capabilities of your Virtual Machine.

Step 1

Start the Virtual Machine - You will reach the grub screen which looks like this

Scroll down to the second option, Advanced options and hit enter





















You will be presented with available kernels and their recovery modes similar to this graphic






















Scroll down to the second option that is the recovery option and hit enter.  You will have a verbose boot sequence that looks like this


















Step 2 

Resume the normal boot - You will get a recovery boot menu.  This has many options that allow you to tweak different settings but for this exercise you will simply resume a normal boot


















When you hit enter on resume, you have an additional dialog like the one shown below that tells you that you are leaving recovery mode and resuming a normal boot.

















Click Enter

Step 3

Normal Boot - Although you have chosen normal boot you will still have a verbose (command line) boot
















When that finishes it will initialize the login screen (lightdm) and you can login as you normally would























Step 4

Install Virtual Box Guest additions - You next step will be to install the VirtualBox guest additions.  This will allow you to get proper screen resolutions and additional hardware resources.

Currently this procedure works for:

Black Lab Enterprise Linux

Black Lab Enterprise Linux for Eduction

Black Lab Studio

Black Lab Embedded

Black Lab Server

XFCE Spin

GNOME Spin

Cinnamon Spin

LXDE Spin

Unity Spin

Weekly 255 Released

Today we have released Weekly Build 255.  With this release we have fixed 159 bugs within the system.  This weekly is based on the KDE desktop and we fixed many of the issues within the KDE desktop as well.

Some of the more prominent fixes include:

  • KDE Specific:  Disappearing network icon - The network manager applet would disappear after periods of use.  This has been fixed
  • KDE Specific:  During live boot the menu would not retract when pressed.  This has been fixed.
  • dmesg would report "Core temperature above threshold"  thermald was the culprit for this error and it has been repaired
  • When logging out of the system it would trigger a reboot.  This has been fixed
  • i915 module not found Error:  The appropriate i915 drivers have been loaded and are not removed during the remaster process.
  • Transfer with Nitroshare would cause .jpg and .png files to be unreadable.  This has been fixed
  • Swap file management now optimized for SSD and FLASH storage users


There are a few bugs that we havent fixed yet


  • Not all Ubuntu branding removed from installer - Will be fixed in Weekly 256
  • Mobile batteries on SurfaceBook, SurfacePro, Lenovo Ideapad and some Dell models even upon full charge report only 56% capacity
