[SOLVED] How to disable KMS?

AurosGamma · 2011-02-26 10:48:34

First of all i wanna say that the rumors were true... Archlinux is a really good distro. Im migrating from Ubuntu so... the installation was a little hard, but the wiki has a really good quality, i have learned in two days much more than i was learning in 1 year on ubuntu.

Im finishing my fresh installation of arch, installing some things to make it looks good, right now im working on splashy but.. i need to disable KMS to install and configure Uvesafb. I know that i can do this writing nomodeset on Grub's menu.lst but what type of nomodeset? I have a Nvidia card with nvidia propietary drives and in the wiki says:

"Procure disabling KMS before attempting to boot into framebuffer. Failure to do so will result in a pitch-black screen, leaving no option but to restart the machine with Ctrl+Alt+Del. For Intel cards, append i915.modeset=0 to GRUB's entry to disable KMS. "

But how i can disable KMS with a nvidia card and propietary drivers?

Thanks!!!

IIRC with NVidia blob drivers it shouldn't be using KMS anyway, as the two aren't compatible with each other, so you shouldn't have to do that, I think.

What do you have in your kernel line in grub? The default one should just boot but I'm not an expert on uvesafb.

You shouldn't need to do anything to disable KMS. The nvidia package has installed a file to blacklist the nouveau module. With the nouveau module not loading because of this blacklist, KMS won't get activated. So just follow instructions to set up uvesafb and you should be set.

Hey thanks, i suspected that the drivers have deactivated KMS by itself, but i wasn't sure...

Now i have splashy running, thanks!!!

I'm having the same issue. I did install the nvidia package, however the kernel still loads the drm module and nouveau right on boot. I removed the nouveau module form /etc/mkinitcpio.conf and also tried adding modprobe.conf in FILES which has an entry to blacklist nouveau.

Any ideas? How can I stop the kernel from automatically loading the drm and nouveau module?
