Ahojda, mám dvě grafické karty:

$>lspci
01:00.0 VGA compatible controller: NVIDIA Corporation G71 [GeForce 7950 GT] (rev a1)
05:00.0 VGA compatible controller: NVIDIA Corporation NV44 [GeForce 6200 TurboCache(TM)] (rev a1)

a tři monitory:

(vlevo)     Eizo L557   - 1280 x 1024 
(uprostřed) Eizo S2201W - 1680 x 1050
(vpravo)    Eizo L557   - 1280 x 1024  

a rád bych je dohromady zapojil tak, abych získal jednu velkou pracovní plochu. Tj. byl bych schopen roztáhnout např. xterm přes všechny tři monitory. Jedna možnost je použít nvidia-settings , což vyprodukuje funkční konfiguraci viz. xorg.conf:

# nvidia-settings: X configuration file generated by nvidia-settings

ovšem v této konfiguraci nefunguje xrandr. Zajímalo by mě, jestli je možné xrandr zprovoznit a zbavit se twinview? Taky rozmýšlím, jestli je lepší připojit dva menší monitory na výkonější kartu a větší monitor sólo na slabší kartu, nebo zvolit jiné hw. zapojení. Máte nějaké doporučení? Předem díky za radu.
