I have installed Ubuntu 13.10 64-bit on my desktop PC, and it seems it's not working properly. I have freezing while typing, the virtual console is not available, if I try go to it my screen is freezing, also the cursor leaves a trace on the screen.
I have tried to install Nvidia graphics drivers (from offsite, and from xorg repositories), but after it my Ubuntu doesn't boot. I see only a white blinking underline character cursor in top left corner of a black screen and nothing more. In that case I have to do a hard reboot, because the screen is frozen and I can't make my system respond in any other way.
I also tried to install Ubuntu 12.04, but the loader gives a message about "low graphics mode" and after that I see only a black screen, and I can do nothing.
For the moment I have reinstalled Ubuntu 13.10, and I am looking for an answer.
Can someone help me?
