Bypassing display chipset with CPU

January 25, 2011 at 04:48:10
Specs: Windows Vista/Ubuntu, Core2 duo
It is a laptop which has display chipset failed(Nvidia 8600M GT to be specific), using the official driver will crash both Windows Vista and ubuntu before entering the logon screens or starting X. Removing the driver (I disable the function of the card in Vista and changing the X server to use the vga mode without loading the module) helps and works nearly perfect except some pattern shown on the screen and some red spots randomly appears in some black area such as the black frame of youtube videoes. The CPU usage appears to be increased compared to the performance before. So, the question is if it is possible to bypass the nvidia chipset and let the CPU to directly working with the video output skiping the involve of the card. Thank you.

Short answer. No.

You need a new motherboard.

Not a chance. Thats like taking the gear box out of a motor car and connecting the crankshaft directly to the axle. It isn't going to work.

If the video card is actually a CARD, replace it. If not, you either need a new motherboard as stated by Richard59, or a whole new laptop. But if it works OK without the "official driver", the problem may be user error. Where are you getting the driver from - Nvidia or the laptop manufacturer?

Thanks all, it is interesting to me that the display is still functioning after the chipset is down so I just wonder if there is any chance to work with CPU solely. The drivers I'm using worked for last three years and hence I am quite sure that something goes wrong with the chipset. Anyway, thanks for all useful comment.
