Group and User settings in Ubuntu Raring Unity and Mate Desktop.

Ubuntu 13.04, Raring Ringtail has no Graphical User Interface or GUI for changing the User and Group Settings. Therefore default option is either to use ‘sudo usermod’ command from terminal, which is not difficult after a little practice. For all other command options use ‘usermod — help‘ at the terminal. But for those who want to do things as usual, like me, may install GUI from Gnome 2 which works for ‘Unity‘ as well as ‘Mate‘. This is the command from terminal (Control+Alt+T):

sudo apt-get install gnome-system-tools

This will install the good old GUI (we were using for past many years) in ‘System>Administration in Mate. However in Unity we have to use Dash and typing “users-admin” shall call the GUI.
All the best.

Alternative to Unity in Ubuntu Raring 13.04: Mate.

Screenshot-Mate-13.04Unity sucks as usual. Ubuntu Raring Ringtail 13.04 does not work properly on older machines (e.g. AMD core 2 with 2GB ram and on-board graphics) any more. It installs alright but xWindow crashes. Ubuntu-Gnome also had the same problem. In such situation Xbuntu (Ubuntu with Xfce) is a better option and we can add ‘Mate’ as Desktop environment to make it even better. Mate is the new name for the classic Gnome 2.0 Desktop. Until 10.04 Ubuntu was shipped with Gnome 2.0 Desktop.

Oracle virtual box error: Kernel driver not installed (rc=-1908) solved.

VirtualBox from Oracle is a great application to run other Operating Systems within the native OS.
We installed virtualbox-4.2_4.2.12-84980~Ubuntu~quantal_amd64.deb on a machine with Ubuntu Gnome 64bit. While it showed no error in installation, but when run, it started to display following error:

Kernel driver not installed (rc=-1908)
The VirtualBox Linux kernel driver (vboxdrv) is either not loaded or there is a permission problem with /dev/vboxdrv. Please reinstall the kernel module by executing
‘/etc/init.d/vboxdrv setup’
as root. If it is available in your distribution, you should install the DKMS package first. This package keeps track of Linux kernel changes and recompiles the vboxdrv kernel module if necessary.

So first we installed DKMS by running a command from terminal “Sudo apt-get install dkms”. This installed DKMS. Now as suggested in above error message we tried running ‘sudo /etc/init.d/vboxdrv setup’ and we were provided with another error message: Continue reading
