I have a display card + display combination that has recently had much problems
during system boot. Some system versions boot just fine to very large text mode,
others create entirely black display.
Is there any way to forbid the DRM from doing "maximize the text display area"
operation at all during the boot? I do want the DRM/KMS to happen latter, but
NOT during system boot!
Best regards, Matti Aarnio

I will emphasize some more: I want to have all of that drm initialization to happen,
EXCEPT do not want to allow it to make display mode change during the boot!
Call me a dinosaur, or whatever, but getting the system to boot to text console
used to be "guaranteed thing", except that now it is not :-( I do not want windows,
I want Linux. When I then see that system did boot correctly, I will MANUALLY
start X.
I might even permit the init-script to start the xdm or other graphical login manager,
but only after the bootup has been completed all the way to userspace!
I tried vga=ask on boot line, but of course it did not have effect on drm.

Boot with nomodeset or radeon.modeset=0 on the kernel command line.
That will disable kernel modesetting at boot. You can then manually
load the modules with or without modesetting once the system is
booted. drm-next also recently got support for forcing the console
mode.

Thanks, that saved the day. The kernel boots to text console just fine, and when
I am happy, log in as my non-privileged self and start X, firmware loading and mode
settings are working correctly.
Of course I would be happier without these boot commandline extras, so
current Fedora 12 (Beta) kernel has some bad radeon drm/dri/kms bits on it.
Couple of weeks ago things did work just fine with modesetting happening
early in the boot. Four weeks ago things failed, and six weeks ago this
modesetting thing did not exist...
Current kernel is:
2.6.31.1-56.fc12.x86_64 #1 SMP
