I have an ATi 7500VE dual head video card and wish to set up dual monitors under Redhat 7.3. I have searched my Redhat install for any information about xinerama, but to no avail. Xinerama is in the control panel, but it is greyed out. I have added the xinerama command to my start up script and to the /usr/X11 file. I have not editted my X86Config-4 file as yet, as I am try ing to find out where and what xinerama are and what has it done for me lately!!! Any help would be greatly appreicated..

Go to the command line and type: whatis xinerama To find out where it is try 'whereis xinerama' and 'locate xinerama'

locate finds nothing, Whereis says xinerama: Whatis says"nothing approriate" (Linux's words, not mine). It's bizaree! Here's my XF86Config-4 file for guidance XFree86 4.2.0 configuration generated by Xconfigurator 4.10.7 Section "ServerLayout" Identifier "Anaconda Configured" Screen "Studioworks" 0 0 Screen "Multiscan" rightof "Studioworks" InputDevice "Mouse0" "CorePointer" InputDevice "Keyboard0" "CoreKeyboard" Option "Xinerama" "on" EndSection # Red Hat Linux 6.0 and later use the xfs font server for improved # interactive performance Section "Files" FontPath "unix/:7100" EndSection # Module loading section Section "Module" Load "dbe" # Double-buffering Load "GLcore" # OpenGL support Load "dri" # Direct rendering infrastructure Load "glx" # OpenGL X protocol interface Load "extmod" # Misc. required extensions Load "v4l" # Video4Linux # Load "record" # X event recorder # You only need the following two modules if you do not use xfs. # Load "freetype" # TrueType font handler # Load "type1" # Adobe Type 1 font handler EndSection Section "InputDevice" Identifier "Keyboard0" Driver "keyboard" Option "XkbLayout" "us" EndSection Section "InputDevice" Identifier "Mouse0" Driver "mouse" Option "Device" "/dev/mouse" Option "Protocol" "PS/2" Option "Emulate3Buttons" "off" Option "ZAxisMapping" "4 5" EndSection Section "Monitor" Identifier "Monitor1" VendorName "Unknown" ModelName "Unknown" HorizSync 31.5-57.0 VertRefresh 50-70 Option "dpms" EndSection Section "Monitor" Identifier "Monitor2" VendorName "Unknown" ModelName "Unknown" HorizSync 31.5-57.0 VertRefresh 50-70 Option "dpms" EndSection Section "Device" Identifier "ATI Radeon 7500 QW Studioworks" Driver "radeon" BoardName "VE" BusID "PCI:1:5:0" EndSection Section "Device" Option "nodri" Identifier "ATI Radeon 7500 QW Multiscan" Driver "radeon" BoardName "VE" BusID "PCI:1:5:0" EndSection Section "Device" Identifier "Linux Frame Buffer" Driver "fbdev" BoardName "Unknown" EndSection Section "Screen" Identifier "Studioworks" Device "ATI Radeon 7500 QW Studioworks" Monitor "Monitor1" DefaultDepth 24 Subsection "Display" Depth 24 Modes "1024x768" EndSubSection EndSection Section "Screen" Identifier "Multiscan" Device "ATI Radeon 7500 QW Multiscan" Monitor "Monitor2" DefaultDepth 24 Subsection "Display" Depth 24 Modes "1024x768" EndSubSection EndSection Section "DRI" Mode 0666 EndSection

xinerama can be loaded to allow multiple monitors on X, but since ATI cards are supported so poorly in Linux, it probably won't work for you. Look around before you give up, though.
