I've taken a closer look and its not only console that looks bad. I think
that observation, that after rescaling to 1280x1024 fonts are rendered
poperly, means here something important. But I have no idea, what.

But in fact my monitor IS connected via a standard VGA connector. It simply
has no DVI plug, only VGA. My graphics card has a single output connector
and a splitter, which allows me to connect two monitors, both using VGA
connector (I'm using only one).

I'll give it a try on Thursday and will let you know, how it behaves.

It would mean, that the only thing left for me is to use a proprietary
NVidia driver. Becouse if the binary driver does something and nouveau not,
it means, that nouveau should be fixed/improved to obtain the same
functionality (which is basic here). Otherwise it's kind of useless...
