Xorg.0.log

The latest git version of nv gets a bit further. I've attached an updated Xorg.0.log. I also noticed that nv is able to work if the proprietary "nvidia" driver has run before it (that is, start X with the nvidia driver, edit xorg.conf to use "nv", then it works).

I used gdb to attach to the X process which seemed to be hung. Here's the relevant backtrace:

The Xorg.log with latest git from a coldboot

The latest git version still doesn't work for me, this time failing to find a valid lvds mode (1440x900 for me).

I'm re-opening this bug since the latest version still doesn't work for me

The Xorg.log with latest git after running once with the nvidia driver

The nv driver works if I start X once with the proprietary nvidia driver. The attached log is from a working nv run.

Proposed fix

Please try the attached patch.

Thanks, that patch successfully brings up X with nv on a cold booted machine.

Excellent.  Marking fixed with commit 08870847.
