If only :( I talked with a developer on #xorg channel and he told me
that he thinks (he was not quite sure about it though) that it is the
graphic drivers job to restore the screen buffers on VT switch. The
strange thing is that I tried with different drivers and it's always the
same. So somehow the drivers are not able to restore the buffer.
does anyone have an idea why this could happen?
