After installing Kubuntu on a Notebook with GeForce Go 6100 graphics card, the tty's were working correctly, but the KDE desktop wouldn't display anything correctly. After installing the nVidia driver using
apt-get install nvidia-current as root, the KDE desktop was displayed correctly. But now the TTY's have a very low resolution (the font is about 4x as big as it's supposed to be) and the flashing kubuntu Plymouth-animation was replaced by a text based animation looking like this:
Kubuntu 13.10 . . . . .
Where the dot's were changing it's color like on Ubuntu (not Kubuntu) bootup.
What happened and how can I fix it?
