screen blacks out after pressing a key on keyboard, specially enter key
- by ahmad598
I have natty, and i have installed kubuntu-desktop package. before installing it, everything was fine but after that, this thing happens:
when I'm typing, after stroking a key, screen blacks out, fan speeds up, and i have to turn off machine by pressing power button. it just happens in many different apps (chromium, hotot, kde proxy settings, ...) and in every environment: unity, kde, gnome 2.
i don't know what details i must provide with this question, and i don't like to remove my kde desktop, or re-install my ubuntu. any ideas are appreciated ;-)
