    SIS 771/671 + Xubuntu 13.04 / 14.04 LTS

    I've just fresh-installed Xubuntu 13.04 on a SIS 671/771 chip notebook. Can't get its normal display resolution 1200x800.
    I've read before that there are hacked drivers for this hideous chip for Ubuntu 12.04 and older, but I can't find one for Xubuntu 13.04.
    Can anyone point me where to look for? (Otherwise downgrade seems like the only option...)
    (How is it that Mageia 3 runs ok on this notebook, but Xubuntu won't...? I prefer to stay in the Ubuntu family)

    Re: SIS 671 771 + Xubuntu 13.04

    Now trying Xubuntu 14.04, in spite of Live DVD working pretty fine (1024x768 instead of expected 1200x800 resolution) after installing resolution went down to 640x480, it won't admit any other option. I guess there has to be an easy fix to this. Any ideas?

    Xubuntu 14.04 works in a near to proper resolution by adding
    Code:
    sudo cp xorg.conf /etc/X11/xorg.conf
    where xorg.conf contains this esoteric things (remember I'm a plain user, willing to migrate from XP to any Buntu with no success yet)
    Code:
