Video driver update

Video driver update

[Onkar Mahajan]

[-- Attachment #1.1: Type: text/plain, Size: 528 bytes --]

Hi,

When I boot into the dom0 kernel. The system is not able to find the
NVIDIA video driver.Normally , when I update the non-pvops kernel
I switch the virtual console and install the
video driver and reboot , then the video driver module gets installed.
But I am not able to do similar thing in the case of pvops kernel.
How can I keep this video driver installed across the kernel updates.
Note that this driver is a proprietary driver from NVIDIA.

(NVIDIA-Linux-x86_64-195.36.
31-pkg2.run)

Please help me.

Regards,
Onkar

i don't think the nvidia driver can work on XEN kernels. i'd use the nv or 
nouveau driver instead. i mean, why would a dom0 need an nvidia driver?

I would think this would not work.. but you never know. Did you run the
package? Did it install/compile the modules? Did it change your Xorg
file? Did you crank up the verbosity of the kernel and Xen to see what
is happening.

Please do look at the PVOPS Wiki (just google for it) for how to set
those verbosity functions.

As far as I know, the nvidia installer explicitly tests for Xen and does
nothing/fails if present.

This can be handled by setting the shell variable

IGNORE_XEN_PRESENCE=1

before starting the installer.

I guess this is as any good place to also point out that there is an
alternative. You can use the nouveau driver (but it does not have yet 3D
support), which works with the Xen PVOPS kernel. Better yet, Kernel
Mode Setting works as well!

For details: http://wiki.xensource.com/xenwiki/XenPVOPSDRM

and if you want to try out the 2.6.34 nouveau driver on a Xen PVOPS
kernel, get it from
git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git branch devel/next.drm
