At work I daily использовал an HP Compaq Элита 8300 (Intel i7), with Убунту Десктоп, Затмение and Netbeans for develop linux embedded программное обеспечение, Java США application and HTML / язык сценариев JavaScript solution, and эксперт browser I использовал Google Chrome.
Last month I upgrade Ubuntu from 14.04 LTS to 15.10 by в new clear installation, and then began the problems, the персональный компьютер randomly крах, шоу black screen for few seconds, and then logout and redirect я to graphical login screen!
I tried some solution found on Веб, install last certified Интер Графикс Дривер, update Ubuntu, and обитал other but not solve my problems.
Now I resolve my problem only when I stop to использовал Google Chrome and переключатель to Mozilla Firefox.
Probabilly the problem is an incompatibility from Chrome and my current pc's configuration.
Хан I do some тест to find what's the реальный problem?
Thanks.
