I have Ubuntu 16.04 and when I launch some fullscreen aplications, they randomly (at a given moment) freeze my display. I can move the mouse pointer using the mousepad but neither I can't click nor press a key combination to exit the aplication. If I press Alt+F1 (I think), then I go completely into CLI. My question is, if I suspect that this is a bug from one or more of my repositories, how can I detect wich of them is buggy and how to file this bug (under which package)?

Thanks for your patiente, as I am new at this.

After some research, and trying to tag my own question with a "freeze" tag which possibly means that this is a bug with a graphic driver, I just found that there are 2 bug reports at Oibaf's "Updated and Optimized Open Graphics Drivers". This bug causes the screen to completly freeze with the exception of the mouse pointer.

Bug Description

During the installation the computer freezes completely except for the mouse pointer. And even that is stuck with whatever shape it happened to have at the time it froze. The steps I have to cause the freeze are run Ubiquity to start the installation open a terminal, run Ubuntu-bug and let it launch Firefox. It will freeze every time then. Even the consoles (ctrl-alt-f1 etc) are unavailable. What kind of information can I collect and how?

Bug #1377878 for Oibaf's repo and Bug #55745 for Xorg Project Team, are related and quite old (reported 2 years and 4 years ago respectively without a fix).

I would suggest, sticking with default Ubuntu drivers, suscribe to #1377878 and wait for a fix.
