[Bug 595653] New: Live CD does not load KMS drivers correctly

Reason: The radeon module is not loaded during boot and KMS is not activated. If I manually load the radeon module from runlevel 3, kms gets activated (resolution switches).

On an installed system, there is an initrd script which loads the kms modules, I think this is not integrated into live CDs yet.
You mean mkinitrd, which adds radeon (+firmware files) and the appropriate agp module to initrd. Still radeon module should be loaded by the radeon driver during Xserver startup. So that can't be the reason. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I'm reopening because I got it working. Seems to be a complex issue. What I've done to get it working: - updated to latest Factory kernel (but it's the same release, just a newer build) - zypper dup to X11:XOrg -> xorg-x11-driver-video-7.5-39.1.i586 - boot with "nomodeset 3" - rmmod radeon; modprobe --ignore-install radeon modeset=1 -> resolution switches - init 5 -> X Server starts up, KDE loads, Compositing works, s2ram/resume works So KMS definately works on my chipset - blacklisting is the wrong solution here IMHO. What does NOT work: a) start X-Server without radeon module and let radeon be loaded by the xorg driver automatically -> I've seen a patch somewhere to load the radeon module *before* querying KMS capability. So the bug is in the driver, not in my hardware b) load radeon module from initrd - it hangs 60 seconds while trying to load firmware radeon/R300_cp.bin - which is odd, because this file exists in my initrd under /lib/firmware/radeon. Double and triple checked this. After this timeout, boot continues, but X Server does not start up correctly. Also unloading the module does not work because it is in use. So if these issues are fixed, KMS should work fine on M24 (and maybe the other blacklisted chipset). ah.. found the patch which could solve a) but did not test it: http://osdir.com/ml/debian-bugs-dist/2010-02/msg04726.html http://permalink.gmane.org/gmane.comp.freedesktop.xorg.drivers.ati/12853 https://patchwork.kernel.org/patch/81379/ That's just a quick googling, I guess you know better where exactly to look for the proper fix. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

It's basically a race condition, depending how quickly the drm loads, it might work on some systems but not on others. Really with KMS, you need to have the drm loaded before X starts. The drm in non-KMS mode doesn't actually do anything until the ddx initialize it things via ioctls, so it loads immediately. For KMS, the drm initializes the hw and memory manager which takes a while longer, so it's not always done loading by the time the ddx queries it for kms support. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Add the missing files and it should work. However, I know why the firmware cannot be loaded: The order of scripts in initrd is: .. 03-kms.sh .. 04-udev.sh .. If nomodeset is set, kms.sh sets "dont_load_modules" - otherwise kms modules will be loaded automatically. BUT: The firmware loader needs a running udev. If I modify the run-all script and insert a "bash" after the udev.sh script, I can manually load them. It's not possible without the udev daemon. I'm not sure if it's enough to just start kms.sh after udev.sh because udev might load the modules automatically (is this the case with this kind of modules?) Otherwise kms would have to pre split in two scripts - the first sets options and always calls dont_load_modules, the seconds (after udev) then explicitely loads the modules. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Well, I don't think that's an option here. I believe it should be done differently by making use of /lib/mkinitrd/scripts/{setup-kms.sh,boot-kms.sh} + /etc/X11/kms-blacklist.*.
However, I know why the firmware cannot be loaded:

Right.
Now what's left? This was originally reported against the live CD - how to proceed there? Either set nomodeset as default on the live cd
This would be fatal on intel graphics. Result would be fbdev.
or load the correct modules somehow (the setup-kms.sh already has some hw-detection which could be re-used there...)
I still don't believe that's possible for a LiveCD. Can't you specify nomodeset manually on the kernel boot commandline of the LiveCD? -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

On my system for example the radeon drm driver was in kms mode but the xorg assumed UMS - this created different problems when logging out and also sometimes when switching to a console (radeon module error messages on console, screen corruption, freeze, ...) But that's a low prio imho, because in general it seemed to work somehow and I was able to install the system. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Should only be required if the default (KMS) doesn't work.

Hmm. This shouldn't happen. As Alex Deucher mentioned this is likely a race.
