I installed unity 5 on my ubuntu desktop. But when i am running it, it is not coming like this i.e. no text is shown.
Seems like you don't have required MS fonts(also it uses IE8).
Try to install winetricks, and then running
winetricks tahoma corefonts ie8
There are is Unity3D-Wine-Support repository on GitHub(with almost same aproach) and pretty big Unity3d Wiki page about running editor on Linux(with several approaches) - you can check them out.
