I installed Ubuntu 12.04 LTS. I can click to open an application like Firefox or LibreOffice Writter and once the app opens I can't click inside...I can't click open or close, or refresh or anything.

One work around is I can log out and log in and now I can click but I have to log out every time I turn the PC on. If I use firefox browser it will freeze the system within 2 min.

Tried downloading Chromium just to go online but while downloading Chromium the system freeze again.

BTW if I log out and log in and I don't use the internet everything will work fine.

Just downloaded and reinstalled Ubuntu again with the same issue. In the virtualBox Ubuntu just works fine but when I install it on a TEST pc I have the issue is there.

you should also include what video card/s you are using, it could be relevant. – TrailRider Jan 27 '14 at 2:34
I've experienced such frequent freezes in the past.. and about "click doesn't work" try pressing Alt + Tab keys.. I don't know why, but that works for me... check this link too: What should I do when Ubuntu freezes? – precise Feb 1 '14 at 4:11

Something similar happen to me a while ago while i was fooling around with the compiz configurations and i solved it by doing the following:

Run the following commands in the terminal, compiz --replace & and after it unity --reset and log out and in again.

Hope it helps, next time try providing more info about your setup, version, shell and some hardware related.

FYI: I get 'ERROR: the reset option is now deprecated'. – Mr. Tea Mar 21 at 18:03
