$>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 1024a 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
# nvidia-settings: version 295.33 (buildmeister@swio-display-x86-rhel47-08.nvidia.com) Sat Mar 17 15:58:15 PDT 2012

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.

což funguje jenom pro 2 monitory na 1 kartě, xrandr vypíše:
Screen 0: minimum 8 x 8, current 2960 x 1050, maximum 4096 x 4096 DVI-I-0 disconnected (normal left inverted right x axis y axis) DVI-I-1 disconnected (normal left inverted right x axis y axis) TV-0 disconnected (normal left inverted right x axis y axis) DVI-I-2 connected 1280x1024+0+0 (normal left inverted right x axis y axis) 337mm x 270mm 1280x1024 60.0*+ 1024x768 60.0 800x600 60.3 640x480 59.9 DVI-I-3 connected 1680x1050+1280+0 (normal left inverted right x axis y axis) 474mm x 297mm 1680x1050 59.9*+ 1280x1024 60.0 1280x960 60.0 1024x768 60.0 800x600 60.3 640x480 59.9Říkal jsem si, že by stačilo nějak "nahodit" tu druhou kartu. Tj. změnit stav z "disconnected" na "connected" :)
Jen by mne zajimalo vyuziti tohohle. Ciste zajem, nic vice. Pro mne plati (11", 13,3" atp.)
People keep telling me the screen is
too small, I usually respond, "that's ok, I didn't want you looking over
my shoulder anyway".
