Description David Ronis 2010-06-07 08:54:52 UTC
The subject says it all.  I've been following the git master for some time.  Things worked yesterday, after upgrading (drm, pixman, mesa, xserver, xf86-video-ati) they don't.  What I see on the console is the summary message:

X: ../../../include/privates.h:122: dixGetPrivateAddr: Assertion `key->initialized' failed.

No errors are reported in Xorg.0.log

Finally, when X bails it leaves me in a graphics video mode.
Comment 1 Keith Packard 2010-06-07 11:50:53 UTC
A stack trace would be really useful here; obviously it's not crashing for everyone...
Comment 2 David Ronis 2010-06-07 14:55:13 UTC

The stacktrace is below.  Note that this is an older machine, a HP laptop, with a Radeon Mobility 9100IGP graphics card.  I have had several, as yet unresolved, issues with this card (e.g., https://bugs.freedesktop.org/show_bug.cgi?id=25597), and most recently GL has stopped working properly.

Here's the stactrace

Comment 3 Keith Packard 2010-06-07 15:40:45 UTC
Looks like your driver isn't calling DRI2ScreenInit. Here's a patch which makes DRI2 simply fail in that case:

Comment 4 David Ronis 2010-06-07 15:57:47 UTC
I applied the patch,  and now X starts.   I'm using the radeon driver.   

From Xorg.0.log

[ 27850.031] (II) Loading /usr/lib/xorg/modules/drivers/radeon_drv.so
[ 27850.031] (II) Module radeon: vendor="X.Org Foundation"
[ 27850.031]    compiled for 1.8.99, module version = 6.13.99
[ 27850.031]    Module class: X.Org Video Driver

I'll atach the rest of the log file.

Shouldn't the patch be committed?
Comment 7 Keith Packard 2010-06-15 15:25:50 UTC
Thanks for testing, this is in commit 505724c5f3e4fc1475fa54f20d08c0c06fb32443
