Guest Diesel Posted May 10, 2008 Report Share Posted May 10, 2008 I've been struggling with my dual monitor setup in Mandriva 2008.0 for 2 solid days now and a lot of coffee support I followed the advice on various posts from several linux websites and so far I got big-desktop to work and I can drag windows between them which is good, but with the following problems: I only have 2 resolution options in ATI Catalyst Control Center: 2560x1024 and 1024x480. Currently I have it set on 2560x1024 but the monitors dont support a high refresh rate at this resolution so they have a lot of flicker at 60Hz. The 1024x480 resolutionis way too low for practical use. The monitors are both AOpen 17" with 1024x768@85Hz as my preferred resolution. My card is an ATI Radeon 9600. When I run fglrxinfo I get the following: [johan@localhost ~]$ fglrxinfo display: :0.0 screen: 0 OpenGL vendor string: Mesa project: www.mesa3d.org OpenGL renderer string: Mesa GLX Indirect OpenGL version string: 1.4 (2.1 Mesa 7.0.1) The xorg.conf file is as follows: # File generated by XFdrake (rev 230776) # ********************************************************************** # Refer to the xorg.conf man page for details about the format of # this file. # ********************************************************************** Section "ServerLayout" Identifier "layout1" Screen 0 "aticonfig-Screen[0]" 0 0 InputDevice "Keyboard1" "CoreKeyboard" InputDevice "Mouse1" "CorePointer" InputDevice "Mouse2" "SendCoreEvents" EndSection Section "Files" EndSection Section "Module" Load "dbe" # Double-Buffering Extension Load "v4l" # Video for Linux Load "extmod" Load "type1" Load "freetype" Load "glx" # 3D layer Load "dri" # direct rendering EndSection Section "ServerFlags" #DontZap # disable <Ctrl><Alt><BS> (server abort) #DontZoom # disable <Ctrl><Alt><KP_+>/<KP_-> (resolution switching) # allows the server to start up even if the mouse does not work Option "allowmouseopenfail" EndSection Section "InputDevice" Identifier "Keyboard1" Driver "kbd" Option "XkbModel" "pc105" Option "XkbLayout" "us(alt-intl)" Option "XkbOptions" "compose:rwin" EndSection Section "InputDevice" Identifier "Mouse1" Driver "mouse" Option "Protocol" "ExplorerPS/2" Option "Device" "/dev/mouse" EndSection Section "InputDevice" Identifier "Mouse2" Driver "evdev" Option "bustype" "0x0003" Option "product" "0x0039" Option "relBits" "+0+1+2" Option "HWheelRelativeAxisButtons" "7 6" Option "vendor" "0x0458" EndSection Section "Monitor" # TV fullscreen mode or DVD fullscreen output. # 768x576 @ 79 Hz, 50 kHz hsync Identifier "monitor1" VendorName "Plug'n Play" ModelName "VM7V" HorizSync 30.0 - 72.0 VertRefresh 50.0 - 160.0 ModeLine "768x576" 50.0 768 832 846 1000 576 590 595 630 ModeLine "768x576" 63.1 768 800 960 1024 576 578 590 616 EndSection Section "Monitor" Identifier "aticonfig-Monitor[0]" Option "VendorName" "ATI Proprietary Driver" Option "ModelName" "Generic Autodetecting Monitor" Option "DPMS" "true" EndSection Section "Monitor" Identifier "aticonfig-Monitor[1]" Option "VendorName" "ATI Proprietary Driver" Option "ModelName" "Generic Autodetecting Monitor" Option "DPMS" "true" EndSection Section "Device" Identifier "device1" Driver "fglrx" VendorName "ATI Technologies Inc" BoardName "ATI Radeon 9500 - X850" Option "DPMS" Option "XaaNoOffscreenPixmaps" "1" Option "DesktopSetup" "horizontal" Option "Mode2" "1024x768" #Resolution for second monitor Option "HSync2" "65" Option "VRefresh2" "60" Option "OverlayOnCRTC2" "1" Option "Capabilities" "0x00000800" Option "PairModes" "0x0+0x0" Option "EnableMonitor" "crt1,crt2" EndSection Section "Device" Identifier "aticonfig-Device[0]" Driver "fglrx" Option "ATIFGLEXTENSION" "Keyboard1" BusID "PCI:1:0:0" EndSection Section "Device" Identifier "aticonfig-Device[1]" Driver "fglrx" Option "HSync2" "65" Option "VRefresh2" "60" BusID "PCI:1:0:0" Screen 1 EndSection Section "Screen" Identifier "screen1" Device "device1" Monitor "monitor1" DefaultDepth 16 SubSection "Display" Depth 8 Modes "1024x768" "832x624" "800x600" "640x480" "480x360" "320x240" EndSubSection SubSection "Display" Depth 15 Modes "1024x768" "832x624" "800x600" "640x480" "480x360" "320x240" EndSubSection SubSection "Display" Depth 16 Modes "1024x768" "832x624" "800x600" "640x480" "480x360" "320x240" EndSubSection SubSection "Display" Depth 24 Modes "1024x768" "832x624" "800x600" "640x480" "480x360" "320x240" EndSubSection EndSection Section "Screen" Identifier "aticonfig-Screen[0]" Device "aticonfig-Device[0]" Monitor "aticonfig-Monitor[0]" DefaultDepth 24 SubSection "Display" Viewport 0 0 Depth 24 EndSubSection EndSection Section "Screen" Identifier "aticonfig-Screen[1]" Device "aticonfig-Device[1]" Monitor "aticonfig-Monitor[1]" DefaultDepth 24 SubSection "Display" Viewport 0 0 Depth 24 EndSubSection EndSection Section "Extensions" Option "Composite" EndSection I tried several options to get the resolution/refresh rate issue sorted but no luck so far.
