enabling shadow effect in ubuntu (inside virtualbox)

Ubuntu has impressive graphical effects. But while running inside virutalbox i was little upset that ubuntu can’t detect any graphics hardware inside virtualbox. I was just thinking how can i enable those nice effects in ubuntu while running inside virtualbox. I was searching in google and i endup with a solution, here i am sharing it.

step1: after logging in ubuntu press alt+f2 (it will open a run application popup)

step2: type gconf-editor in there (it will open configuration editor).

step3: in configuration editor find app->metacity->general->compositing_manager (mark compositing manager checked and it will enable the shadow effect)

enjoy 😉

Installing VirtualBox Guest Additions in Ubuntu

Step 1: After starting the ubuntu in VirtualBox Select Device->Install Guest Additions… from VirtualBox menu.

Step 2: Now in ubuntu open terminal and type the following bash command to install the VirtualBox guest addition

cd /media/cdrom
sudo bash ./VBoxLinuxAdditions-x86.run

Then it will ask for the password, type your password and just after that you will have VirtualBox guest addition installed in your ubuntu. If you have older version of Ubuntu then it might require to upgrade your Linux kernel.

Here VBoxLinuxAdditions-x86.run is the file name of my VirtualBox guest addition.

Basic Shell Commands

To speak about the truth, I actually don’t dislike Linux, but i don’t feel comfortable on it. But i am feeling it is going to be important day by day specially in developer society (I don’t know, home user will ever choose Linux for their every day computing). I am learning some shell commands (they are not many but TOO many!!) here i listed some basic commands (just for me):

cd—Changes directories
chmod—Changes file access permissions
cp—Copies files
du—Prints disk usage
find—Finds files by searching
grep—Searches for a string in input
less—Filter for paging through output
ln—Creates links between files
locate—Finds files from an index
ls—Lists files in the current directory
make—Compiles and installs programs
man—The manual page reader
mkdir—Makes directories
mv—Moves files
ps—Lists processes
rm—Deletes files and directories
ssh—Connects to other machines
