$>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 Section "ServerLayout" Identifier "Layout0" Screen 0 "Screen0" 0 0 Screen 1 "Screen1" RightOf "Screen2" Screen 2 "Screen2" 1280 0 InputDevice "Keyboard0" "CoreKeyboard" InputDevice "Mouse0" "CorePointer" Option "Xinerama" "0" EndSection Section "Files" EndSection Section "InputDevice" # generated from data in "/etc/conf.d/gpm" Identifier "Mouse0" Driver "mouse" Option "Protocol" Option "Device" "/dev/input/mice" Option "Emulate3Buttons" "no" Option "ZAxisMapping" "4 5" EndSection Section "InputDevice" # generated from default Identifier "Keyboard0" Driver "kbd" EndSection Section "Monitor" # HorizSync source: edid, VertRefresh source: edid Identifier "Monitor0" VendorName "Unknown" ModelName "Eizo L557" HorizSync 31.0 - 64.0 VertRefresh 59.0 - 61.0 Option "DPMS" EndSection Section "Monitor" # HorizSync source: edid, VertRefresh source: edid Identifier "Monitor1" VendorName "Unknown" ModelName "Eizo L557" HorizSync 31.0 - 64.0 VertRefresh 59.0 - 61.0 Option "DPMS" EndSection Section "Monitor" # HorizSync source: edid, VertRefresh source: edid Identifier "Monitor2" VendorName "Unknown" ModelName "Eizo S2201W" HorizSync 31.0 - 65.0 VertRefresh 59.0 - 61.0 Option "DPMS" EndSection Section "Device" Identifier "Device0" Driver "nvidia" VendorName "NVIDIA Corporation" BoardName "GeForce 7950 GT" BusID "PCI:1:0:0" Screen 0 EndSection Section "Device" Identifier "Device1" Driver "nvidia" VendorName "NVIDIA Corporation" BoardName "GeForce 6200 TurboCache(TM)" BusID "PCI:5:0:0" EndSection Section "Device" Identifier "Device2" Driver "nvidia" VendorName "NVIDIA Corporation" BoardName "GeForce 7950 GT" BusID "PCI:1:0:0" Screen 1 EndSection Section "Screen" Identifier "Screen0" Device "Device0" Monitor "Monitor0" DefaultDepth 24 Option "TwinView" "0" Option "TwinViewXineramaInfoOrder" "DFP-0" Option "metamodes" "DFP-0: nvidia-auto-select +0+0" SubSection "Display" Depth 24 EndSubSection EndSection Section "Screen" Identifier "Screen1" Device "Device1" Monitor "Monitor1" DefaultDepth 24 Option "TwinView" "0" Option "TwinViewXineramaInfoOrder" "DFP-0" Option "metamodes" "nvidia-auto-select +0+0" SubSection "Display" Depth 24 EndSubSection EndSection Section "Screen" Identifier "Screen2" Device "Device2" Monitor "Monitor2" DefaultDepth 24 Option "TwinView" "0" Option "TwinViewXineramaInfoOrder" "DFP-1" Option "metamodes" "DFP-1: nvidia-auto-select +0+0" SubSection "Display" Depth 24 EndSubSection EndSectionovšem 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.

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" :)
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".
