Running Ubuntu 12.04 During installation of a few programs (Gparted and some others) my computer unexpectedly shut down. When I restarted my machine everything appeared normal. However, every program I open, whether it be terminal or Firefox, the title bar is missing. In other words there is no window dialogue other than File, Edit, View, etc... I don't have the option to close, minimize or maximize. In addition to the absent title bar things don't seem to load quite right. For example, when I load Firefox and go to google.com search results seem to be improperly underlined/not underlined at all. Picture quality is not bad; things just don't load fully/corrupted looking textures and graphics.

Log in with Unity 2D, open ccsm (Compiz config settings manager) or download it with sudo apt-get install ccsm and go to Preferences at the bottom and choose Reset to defaults and then choose Unity from the list. Then you can log in into Unity 3D (the normal one) and everything works :)

I had this error today too and that worked for me.
Notice: Probably you have to log in with Unity 3D to change the settings, I am not totally sure anymore. But give both a try ;)

Thanks to Ryan McClure for this addition:

If by any chance Unity 2D has the same issue (it happened to me once before, so I can relate :P) and neither shell does not allow you to open terminal, press Ctrl+Alt+F1 to open a TTY session. From here, enter your username and password and continue to do the commands thonixx gave you.

Thanks Ryan :) I'm doing my best sharing my experience for other users. – Michael Tanner Apr 27 '12 at 0:08
I don't know what's going on...but I did the Ubuntu 2D at login and when it booted up it looked terrible. I don't even know how to describe the poorness of quality...black screen, the launcher was a mess...so I did the ccsm thing in regular Ubuntu and then when I rebooted and logged in (into normal Ubuntu) and the launcher and the taskbar thing at the top are completely gone...I have my wallpaper though :P – Preston Zacharias Apr 27 '12 at 0:32
What commands are you referring to? – Preston Zacharias Apr 27 '12 at 0:33
Go to ccsm -> Preferences -> Press Restore to defaults -> Reboot -> Go to ccsm -> ("Default" should be selected now") Change it to "Unity" -> Reboot If this does not work please post a comment. – Michael Tanner Apr 27 '12 at 0:37

After running Pinta on 12.04 today, my windows borders and title bars disappeared. I got them back running CCSM - Effects - Window decoration: turn off and on again.

In the past, when this would happen, we would simply run /usr/bin/compiz-decorator --replace from the run dialog.

An easier way was to use fusion-icon from the repository, which is an icon that enables, disables, and restarts Compiz, and change the currently used window manager and/or window decorator.

By the way, it's the window decorator that is in charge of the titlebar, etc.
