Re: [Xen-users] NVidia 169.07 on XEN

["Emre Erenoglu" <erenoglu@xxxxxxxxx>]

I'm using standard nvidia-setting application to create the xorg.conf. nothing special.  The problem may be in the kernel?

I did.  Without the patch it would not compile for me.  What modules are you loading in your xorg.conf?

did you use this patch before compiling? (attached)

I did, same issue.  It locks the PC up cold.

so try version 100.14.19

BTW, I'm using standard xen kernel 2.6.18-8

I did that and was able to get it to compile fine.  When I start X it locks the machine up and I have to pull the power.

Hi Ryan, I'm using 100.14.19 and it works fine. You need to compile it with IGNORE_XEN_PRESENCE=y in your environment.

Br,

First I know XEN is not supported, but I have been able to use the NVidia drivers on it before. I have been able to get the NVidia 169.07 drivers to compile, but when I startx it locks up cold.  Has anyone had any luck with the new drivers?
