Mam takovy pocit, ze nekdo neco takoveho uz resil. Podivej se do /var/log/Xorg.0.log - melo by tam byt od ovladace proc ktery mod vybral nebo ne. Podle me ale budes mit nejake starsi CRT ktere neposkytuje EDID informace, takze grafika nevi co ma nastavit a
Modes “nvidia-auto-select”
tedy nemuze fungovat.
Tzn. hledej jak vypnout zjistovani EDID informaci a jak nastavit Modes rucne (z hlavy to nevim, ale je to popsane nekolikrat i tady).
