    fired video card?

    I have a Matrox G00 dual headed card, and it worked like a charm until my power supply overheaded and almost caught fire. As a result I plugged my harddrive (with a kernel compiled for a i586) into a PII computer along with my video card. LInux booted fine my my hd wasnt damaged at all and both my monitors displayed the console fine. I changed the location of my card's bus in xorg.conf and fired up X. One monitor (#1) works and #2 is all garbled, showing stuff from #1 and #2. Here is some relavant info:

    bash-2.05b# lspci

    From xorg.conf:
    Section "Device"        
            Identifier  "Card0"
            Driver      "mga"
            VendorName  "Matrox Graphics, Inc."
            BoardName   "MGA G400 AGP"
            BusID       "PCI:2:0:0"
    Section "Device"
            Identifier "Card1"
            Driver "mga"
            VendorName "Matrox"
            BoardName "MGA G400 AGP"
            BusID "PCI:2:0:0"
            Screen 1
    Any help would be thoroughly enjoyed. Thanks

    how do you expect xorg to tell the difference between BusID "PCI:2:0:0" and BusID "PCI:2:0:0"?

    It's the same card. It's just creating two virtual devices so that X can run on each monitor.

    If the card worked one day and doesn't now, I'd have to say that it's dead. I don't know of any other things you can try except maybe another computer?
