nvidia module only working after gdm restart

[Fridtjof Busse]

I'm using the nvidia driver on lucid for a GT240. The driver installs fine, but on reboot Xorg complains about an unusable configuration and does not start:

(EE) Jun 10 08:11:08 NVIDIA(0): Failed to initialize the NVIDIA kernel module. Please see the
(EE) Jun 10 08:11:08 NVIDIA(0): system's kernel log for additional error messages and
(EE) Jun 10 08:11:08 NVIDIA(0): consult the NVIDIA README for details.
(EE) NVIDIA(0): *** Aborting ***
(EE) Screen(s) found, but none have a usable configuration.

After switching to a tty and running "/etc/init.d/gdm restart" (the "restart X" option in the rescue X11 windows does not work), Xorg comes up just fine without any errors and nvidia works.
There are not nvidia-related errors in the kernel-log.
Is there some sort of race-condition between modules or an incomplete blacklist?

Creating a custom blacklist and updating the initrd solved the problem (I did not yet identify one specific module, so this might be more modules than necessary):

blacklist vga16fb
blacklist rivafb
blacklist nvidiafb

So it seems /etc/modprobe.d/nvidia-graphics-drivers.conf does not blacklist enough modules. My guess is that the framebuffer blocks the nvidia module from loading properly on the first try.

That version is no more supported; please open a new bug report if the actual archive found version also has the same issue.
