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.
