Dotaz: Xinerama na ntb - lagy

[H0ax]

Dobré dopoledne,
mám gentoo (2.6.20-gentoo-r8) s podporou xineramy a notebook Acer Aspire 3000 s grafikou SiS (lspci):

01:00.0 VGA compatible controller: Silicon Integrated Systems [SiS] 661/741/760 PCI/AGP or 662/761Gx PCIE VGA Display Adapter

Při výstupu jen na monitor notebooku je vše ok, nikdy s tím nebyly problémy. Pokud upravím xorg.conf na podporu xineramy, tak v 50% zatuhne notebook při startu X (nelze se nikam přepnout). Pokud najede, tak xinerama funguje, ale s dvěma problémy.
1. na obou plochách je myš (ovšem reaguje jen ten ukazatel na ploše, kde skutečně pracuji)
2. každou chvíli je několika sekundové vytuhnutí pc a to tak, že se nelze ani nikam přepnout, zastaví se hodiny. Pc se třeba za 5-10 sekund opět rozběhne.
Přikládám xorg.conf:

Tak jsem zjistil, že pokud oba displaye nastavím na stejné rozlišení, tak k zásekům nedochází. Je to pro mě záhada :-/
