Yesterday i updated my new Ubuntu installation, downloaded realtek drivers, downloaded nvidia drivers, downloaded java and adobe flash player.
But before that all mouse and keyboard wasnt working so i unplugged them and plugged them in.
Than i wrote acpi=off but didnt update grub.
I updated realtek drivers. Reboot. Than i updated Ubuntu.
I think nvidia drivers came with update.
Than i downloaded java and flashplayer, installed them, typed sudo apt-get update.
Than i just shuted down and went to sleep. Now i have a blackscreen after startup, there always stands something like usb 2-2 cant set config and usb device keyboard.
So i wanted to try something in the recovery = keyboard not working there.
I also tried to boot up with nomodeset but still same problem.
So can you help me?
