Borderless Windows in Unity 3D after minimizing
 

I am using Ubuntu 11.10. Recently I am facing a problem. After logging in into Unity (3d), when I minimize windows, the window border along with the close, maximize and iconify buttons disappear. My window manager is Compiz. Please not that this problem does not happen if I log in with Gnome Classic or Unity 2D.

If you're using Ubuntu 11.10, you're using a long dead version of Ubuntu, and the fact this Ubuntu 11.10 may be too old to cooperate with your hardware (if the hardware is newer) may be contributing to the problem. 11.10 was EOL'd in April, 2013.

If you have recent hardware, you'll want to jump to more recent 14.04 or 15.04, and this will require a clean install. The next version of Ubuntu, 12.04, is a long term support release, and will probably be updated with support for newer hardware (beware it may not, I'm not sure), and will be supported until April, 2017.

Upgrading from 11.10 to 12.04 is painless, and would help a lot at least with security. It still has Unity 2D as well.

I know, but the point is, I have used 11.10 for over a year without facing any problem of this kind. It happened suddenly, that is why I am trying to find the reason. It will be very helpful if you help me to find the reason.

Upgrading to 12.04, 14.04, or 15.04 is still a very, very good idea. Your data could be left intact and this issue could be solved, especially if you did a clean install

But on 11.10, did you install any updates or change any configurations? How did it work before using Compiz? What happens if you run Unity 3D in a fresh user profile? How old is your hardware?

Sorry, but it seems I am now happy with Gnome Classic, so I am closing this thread. Thank you for your support.

Always glad to try to help. Just beware of the dangers of EOL, and good luck!

Hi, Subhraman. I understand that you have your questions and support addressed. But I would like make an important mention, for the record and anyone else that might be reading this thread for support.

There is lots of risk involved in using an unsupported version of an OS. It goes the same with any OS, including Microsoft.

Hackers are out there working just as vigilant as the developers. OS' that no longer have security updates are a risk. Some people run programs for hours (days at a time) scanning for computers connected to the Internet that has vulnerabilities.

If you are a good enough programmer to be up on all the possible exploits, then you may be safe. But for the majority, they would best be using a supported version so that they can have the latest security updates.

There are ways to configure most versions for the look and feel that you prefer and have the needed security... or at least best updated security.

For anyone else that don't like to update versions, keep in mind that the even number versions that ends in .04 (such as 14.04) is supported for 5 years. So if you upgrade to 14.04 you'll have official support and updates all the way to 2019.
