put "modeset=0" to the grub kernel append line and it's like having no
kms at all. that should fix any remaining issues.
If running kms fails on a system it happens in early state when
filesystems are not yet mounted. So there should be no risk to enable
kms by default. It's simply the future.
Fedora has kms enabled for intel, radeon and even nouveau in their
rawhide devel tree kernel. We should probably do the same for Intel
and Radeon. At least for Radeon it's a must.
Radeon requires kms enabled by default. kms can not be enabled via
append line switch because a module is missing and is not built at all
when not setting kms the default. There's also a pending xf86-video-ati
update pending we will need to get kms + 3D.
For nouveau: kms is currently completely unusable in our distribution.
You need 5-10 times boot attemps to get it up and running. Without kms
it's working quiet well again. kms can be enabled with modeset=1 if
wanted. We are in contact with upstream devs. See also
Also Intel seems to work very well in all my systems.
I'd vote for enabling kms on Intel and Radeon systems now as the
default one. Nouveau is not yet ready. Maybe we should put a news on
our page when this will happen.
