Hi all, I'm running RH7.3 on a machine with an ATI Radeon 7500 PCI 64MB card (Built by ATI). I'm using the card in dual-head mode, driving two Dell E171FP analog flat panels, with a DVI->VGA converter on the DVI port. Xinerama is enabled. The system basically works -- I've got a dual-headed X system running just fine, but there are some display glitches that I can't seem to get rid of. Any help would be greatly appreciated. One odd thing is that X identifies the card as a "ATI Radeon 7500 QW" and looking at the XFree86.0.log, it seems to think this is an AGP card. It's not though, it's definitely a PCI 7500. I don't know if that's significant. First, the screen running off the VGA port looks pretty sharp, except that there are ghost lines moving off to the right for all vertical lines displayed. E.g. the inside left edge of my Mozilla windows has about 5 ghost lines moving into the body of the window at decreasing intensities. The problem is worse with saturated window border colors (e.g. red) and light backgrounds. Second, the screen driven off the DVI port has lots of fuzziness that no amount of pixel clock or phase settings gets rid of. There are very heavy vertical ghosts again moving off to the right, but they are fewer, darker, and closer together than on the VGA screen. Third, console mode has problems. While the text is quite sharp (in contrast to the images under X), the two screens are mirrored and way too far to the left. The left, say 1" or 2" of text is cut off. I'm less suspicious about the monitors and cabling because I've driven the same hardware off an ATI 8500 Mac card on my OSX G4 and they look great. Very sharp, no ghosts, no glitches. Any advice is greatly appreciated. I've attached my XF86Config-4 file below. XFree86.0.log available on request. -Barry -------------------- snip snip -------------------- Section "ServerLayout" Identifier "XFree86 Configured" Screen 0 "Screen0" 0 0 Screen 1 "Screen1" RightOf "Screen0" InputDevice "Mouse0" "CorePointer" InputDevice "Keyboard0" "CoreKeyboard" EndSection Section "Files" RgbPath "/usr/X11R6/lib/X11/rgb" FontPath "unix/:7100" ModulePath "/usr/X11R6/lib/modules" EndSection Section "ServerFlags" Option "Xinerama" "On" EndSection Section "Module" Load "dbe" Load "dri" Load "extmod" Load "glx" Load "record" Load "xtrap" Load "speedo" Load "type1" EndSection Section "InputDevice" Identifier "Keyboard0" Driver "keyboard" EndSection Section "InputDevice" Identifier "Mouse0" Driver "mouse" Option "Device" "/dev/mouse" Option "Protocol" "MouseManPlusPS/2" Option "Emulate3Buttons" "off" Option "ZAxisMapping" "4 5" EndSection Section "Monitor" Identifier "Monitor0" VendorName "DELL" ModelName "DELL E171FP" Option "DPMS" EndSection Section "Monitor" Identifier "Monitor1" VendorName "DELL" ModelName "DELL E171FP" Option "DPMS" EndSection Section "Device" Identifier "Card0" Driver "ati" VendorName "ATI" BoardName "Radeon 7500 QW" BusID "PCI:1:11:0" Screen 0 EndSection Section "Device" Identifier "Card1" Driver "ati" VendorName "ATI" BoardName "Radeon 7500 QW" BusID "PCI:1:11:0" Screen 1 EndSection Section "Screen" Identifier "Screen0" Device "Card0" Monitor "Monitor0" DefaultDepth 24 SubSection "Display" Depth 24 Modes "1280x1024" "1280x1024" EndSubSection EndSection Section "Screen" Identifier "Screen1" Device "Card1" Monitor "Monitor1" DefaultDepth 24 SubSection "Display" Depth 24 Modes "1280x1024" "1280x1024" EndSubSection EndSection _______________________________________________ xfree86-list mailing list xfree86-list@redhat.com https://listman.redhat.com/mailman/listinfo/xfree86-list IRC: #xfree86 on irc.redhat.com
