Nvidia and Intel cards issue in Debian
I have two video cards, an Intel GMA3000 and an NVidia 8500GT (NV).
My OS is Debian testing.
In the BIOS I can choose one of the cards as primary to see through that card the BIOS screen, GRUB and Debian loading process until GDM.
If I choose the NV card as primary, I see the BIOS screen, GRUB and then I got a Kernel Panic.
Otherwise, choosing the Intel VGA in the BIOS and keeping the Monitor plugged to the NV output I don't see anything until GDM, but everything works. (That's how I'm using the PC right now, and what I'm trying to solve)
Does anyone know what is the reason of this problem?
Why does is throw a Kernel Panic?
Looking for a long time in the net I've found a workaround that worked for me in Ubuntu 9.10:
It consisted in adding
But then I couldn't use the Intel card as a secondary monitor.
Now, in Debian, that doesn't work. I've tried with combinations of driver blacklisting:
If i try to load intel_agp or agpgart into kernel I got an error because they do not exist. But blacklisting i915 should work as in Ubuntu.
The ideal solution would be to have BOTH cards working. But at least I would like to blacklist the Intel card and use NV as primary without Kernel Panics.
Thank you very much for your help!
Extra information about my pc:
Try disabling the Intel kms, http://wiki.debian.org/KernelModesetting
In /etc/default/grub edit the GRUB_CMDLINE_LINUX_DEFAULT= line and change it to
While you are in there tinkering you might want to go ahead and disable ipv6. Not that it has anything to do with the problem.
That didn't work. I'm still getting a kernel panic. I've searched about KMS but didn't found any working solution. I'm totally stucked.
Thanks for your help!
Well.. I've found a workaroud, and now I'm working just like in Ubuntu. I've disabled Intel VGA by adding agp=off to Grub.
However, this is not the real solution, because now I can't use the Intel VGA (for example to dual-head)
I'm still hoping to find the real solution or just a good explanation of the issue :)
Thank you very much!
