I think my title is pretty self explanatory but I get the message "unknown chipset" when I'm trying to install Ubuntu.

It seems to be since I changed my graphic card from the GTX 570 to a GTX 970. I even used an old iso I used before and I had the same issue.

Here is a list of messages I'm getting :

unknown chipset
failed to create 0x80000080
Asking for cache data failed
Assuming drive cache: write through
enter help for a list of buil-in commands.

initramfs

Any ideas what I could do to fix this?

Thanks.

  • The standard Ubuntu NVidia drivers generate some problems on slightly older and slightly newer NVidia hardware. If you want more then the standard Ubuntu repository drivers, install the xorg.edgers PPA. As the xorg.edgers group ask not to give installation instructions directly without linking to their page, this is the best I can do. If you don't know what a PPA is or need some guidance after reading their page, leave a comment below.

I've been trying to find a solution to this problem for a while now. I tried various kernel and driver combos but nothing seemed to work.

Now it seems like the latest kernel (3.13.0-49) and xorg.edgers nVidia driver (nvidia-349) updates have fixed the "unknown chipset" problem. To get those updates you'll either have to use onboard graphics if your CPU/motherboard has onboard or drop back to the old GPU temporarily.
