Post M11 manual error, section 5.5, Kernel modeset issues
I think this might be an error:
Quote:
Kernel modeset issues. Add the cheat code radeon.modeset=0 or nvidia.modeset=0.

I think it should be nouveau.modeset=0.

That's what sgfxi adds to the menu.lst entry when you've used sgfxi to install the nvidia driver. It's also what works to disable kernel-modesetting in the tests that I've done. The `nvidia.modeset=0' cheat didn't work to disable KMS in my tests.

This can be tested by first removing/renaming any nouveau blacklist entries that are in the /etc/modprobe.d/ directory. {Warren uses a /etc/modprobe.d/nvidia-kernel-common.conf file to blacklist the nouveau driver and sgfxi uses a /etc/modprobe.d/kms-sg-blacklist.conf file}

Then remove any/all of the following cheats: nomodeset, nouveau.modeset=0, nvidia.modeset=0, nvidia-modeset=0 from the kernel options line.

Without the nouveau blacklisting and without any of the cheats mentioned above you should get a blackscreen if you're using the nvidia driver. You should also get a blackscreen using either nvidia.modeset=0 or nvidia-modeset=0. Using the nouveau.modeset=0 cheat should allow it to boot okay.

That makes me realize that the M11 Manual link on the tab above needs to be updated to the current version.

EDIT: done

I think there's also a i915.modeset=0 cheat for disabling kernel-modesetting for Intel video that might also be mentioned.
