I have insatalled ubuntu linux OS. After some misuse some Tool bar was missing..
I'm not able to configure my the Tool bar ..
Since tool bar like Build project,compile project,close,ebuild project,Execute tool bar r missing .
I followed d path// Setting->configure tool bar->build tool bar<kde troll project>->apply.
But it is not coming..
Is there any other way../or What is package missing dat I should install??
