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

My desktop wallpaper for April 2013.

I liked a  picture of Red Rose, the way it turned out and I decided to use it as wall paper this month. Screen shot of Desktop is here:

Screenshot from 2013-04-04 12:22:49Presently I am using Ubuntu-Gnome Desktop. It does not have Unity. It is better than Lbuntu. That had many problems in relation to graphics. The original Picture of Red-rose is about 2.3 MB and I shall provide a link asa asked by somebody.

Ubuntu Precise Problem: White Screen of Death!

It is said that over a period of time two enemies start to resemble each other. Ubuntu Linux taking on Windows 8 with Unity has started to resemble the Windows. The famous Window’s blue screen of death and black screen of death has taken avatar in Ubuntu as White Screen of Death. Continue reading

Update Manager in Ubuntu 12.04 crashes with unresolvable problem! (Solved)

The buggy Ubuntu has become what used to be ‘Windows 95’ i.e. crashing without reason (or user stimuli) whatsoever. Rather falling under its own weight. I have already replaced Ubuntu Precise vanilla 12.04 with Linux Mint 13 on two computers. It appears that time has come for change that will be away from Ubuntu. There is nothing more annoying than working for first day after holidays and being greeted with a crash report. Today the Update Manager Crashed with following message and advice to report bug:

An unresolvable problem occurred while initializing the package information.

Please report this bug against the 'update-manager' package and include the following error message:

'E:Encountered a section with no Package: header, E:Problem with MergeList /var/lib/apt/lists/security.ubuntu.com_ubuntu_dists_precise-security_main_i18n_Translation-en, E:The package lists or status file could not be parsed or opened.'

This is the error message from “apt-get update”:

Reading package lists... Error!
E: Encountered a section with no Package: header
E: Problem with MergeList /var/lib/apt/lists/security.ubuntu.com_ubuntu_dists_precise-security_main_i18n_Translation-en
E: The package lists or status file could not be parsed or opened.

Executing following command

 sudo apt get install -f

merely repeated the above message.


It appears that it is a well-known bug and a persistent one. There is some mix-up in package lists. Executing following commands at Terminal deleted existing lists and resolved the problem:

sudo rm /var/lib/apt/lists/*

The above did give an error that it can not remove the ‘partial’ as it is directory. But we ignored it and updated the system manually from the terminal with following command:

sudo apt-get update

The update took longer but it resolved the problem for now. Thus started the New Year 2013.
