Disable on-board video? Nov 1st 2012, 01:42 I've spent the better part of two days trying to find a way to disable an on-board video card on a machine that was given to me. It's an old Dell PowerEdge SC440 server, dual-core Xeon 1.86GHz processor and 4-G of ram. I recently installed a nVidia GeForce 8400 in it, and thought the card works great in X, when I switch to a console the text is unreadable. Searching for a cause I found the consensus is the two cards can't co-exist. The output of 'lspci | grep VGA' shows: 05:07.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI ES1000 06:00.0 VGA compatible controller: NVIDIA Corporation G98 [GeForce 8400 GS] (rev a1) Some time on Dell's site shows the card can't be disabled in bios, nor are there any motherboard switches or jumpers to do it. Searching around I found that most believe Dell just omitted any way of disabling the card on the belief that it would never be used for anything other than a low-cost server. I'd like to somehow stop the kernel from recognizing the AMD card so it uses the nVidia for the default, but hours upon hours of looking at docs on kernel.org has only taught me that I'll never understand kernel-talk. Searching on forums have yielded nothing usable either. Anyone had a similar problem, or know a way of telling the kernel to ignore the on-board card? Or... know which wire to cut to permanently disable it? Any help or ideas are appreciated. Oh, if it matters I'm running openSUSE Tumbleweed with kernel 3.6.4-9. Rob
