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 Created attachment 12033 [details]
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.
Created attachment 12038 [details] [review] 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. |
