X segfaults with xf86-video-intel-2.20.3 and ati-drivers-12.6 Reproducible: Always Steps to Reproduce: (This is a AMD+Intel muxless platform running AMD Radeon HD 6630M and Intel i5 2410M.) 1. run startx 2. screen went black and then some message in Xorg's log appears 3. Xorg's X server segfaults Actual Results: Xorg segfaults and fallbacks to tty. Expected Results: Xorg does not segfault and KDE (or whatever) starts. xf86-video-intel used to work quite well with ati-drivers, say 2.20.2 did a good job working with ati-drivers-12.6. and it is in 2.20.3 that breakage occurs. My speculation is that changes related to hardware ID's took place in xf86-video-intel and ati-drivers fail to recognize that.

Same here (muxless intel+ati). Had to downgrade to 2.20.2.
Please test with latest xf86-video-intel and remove all the i915 kernel module options when you are doing it, some of those are known to be broken and causing problems, useful und safe options are enabled by default already.
Does this still happen with ati-drivers-12.9? This package is in the x11 overlay for now because it is an embedded release with some problems.
(In reply to comment #6) > Does this still happen with ati-drivers-12.9? This package is in the x11 > overlay for now because it is an embedded release with some problems. The latest version of xf86-video-intel that remains working with the 12.9 of ati-drivers (embedded) is still 2.20.2. Otherwise, X still segfaults. Tested on xf86-video-intel 2.20.8. Mr. Chris Wilson needs to wait for Debian (sid) to upgrade the drivers there to take a look into the issue. Therefore, the problem should remain unfixed unless xf86-video-intel's announcement says otherwise.
After xserver 1.13 stabilization, this now happens on stable gentoo.
X Server 1.13, xf86-video-intel 2.20.13 segfaults at start. Downgraded to 2.20.2.
As a stable user, I tried to downgrade back to 2.19.0 (the latest stable version before 2.20.13), which failed (due to the new X server, I guess). Had to "unmask" 2.20.2 (AND mask 2.20.12), that works now. Bit of a suboptimal situation here for stable users, I'd say. Maybe stabilize 2.20.2?
There is a patch for xf86-video-intel that fixes this: https://bugs.gentoo.org/show_bug.cgi?id=444560
*** Bug 444560 has been marked as a duplicate of this bug. ***
According to the launchpad bug, the issue is fixed in ati-drivers-13.2_beta Can you verify?
Yes it's fixed, even in 13.1
(In reply to comment #14) Thanks, marking as FIXED then.
There's still a problem with xf86-video-intel >2.20.2 and ati-drivers, as described here: http://forums.gentoo.org/viewtopic-p-7233812.html I have the exact same problem. Tried with ati-drivers-13.1 and 13.2_beta7. xf86-video-intel-2.20.2 is the only version that worked - 2.19.0 fails to compile and >=2.20.13 fails to start X with the error shown in that forum post. I've just spent half the day to get X to run with 2.20.2 removed from the tree, no success. I'll gladly help with fixing this, tell me what info you need. Until then, please put 2.20.2 back.
Have you tried disabling SNA?
(In reply to comment #17) > Have you tried disabling SNA? That worked, thanks a lot. Ok now I may be blind and dumb, but I didn't see any clue anywhere that SNA (which is enabled by default in the desktop profile) could be the problem here. Perhaps an elog message would be a good idea? In any case, this elog message from ati-drivers seems kinda outdated now that xf86-video-intel-2.20.2 is gone from the tree: WARN (postinst) It is reported that xf86-video-intel-2.20.3 and later cause the X server to crash on systems that use hybrid AMD/Intel graphics. If you experience this crash, downgrade to xf86-video-intel-2.20.2 or earlier. For details, see https://bugs.gentoo.org/show_bug.cgi?id=430000
How can you mask this bug as fixed? Just add some warning? I admit that I'm also a blind person and do not notice the warning in this a little long elog. Why cann't we just automatically disable sna, or just when VIDEO_CARD contains fglrx? Also who needs xf86-video-intel-2.19.0 which cannot be compiled?
(In reply to Yichao Zhou from comment #19) > How can you mask this bug as fixed? Just add some warning? I admit that > I'm also a blind person and do not notice the warning in this a little long > elog. I don't think there is anyone too keen on actually fixing this one properly, as ati-drivers is mostly closed source. > Why cann't we just automatically disable sna, or just when VIDEO_CARD > contains fglrx?

> It's not admissible to silently disable features on gentoo. I think only disable sna on hybrid system has no problem, since it is reported that casusing problem at that platform. This is not so hard to archieve by USES flag. Also you can yield a warning about this so we can make it not so silent. Crash on a stable arch is really very rare. This is the my first crash with stable arch which is not caused by kernel misconfiguration. For stable arch, stablility is more important than feature, isn't it?
Or ar least, write something like REQUIRED_USE="video_cards_fglrx ? ( !sna )"
(In reply to Yichao Zhou from comment #22) > Or ar least, write something like > > REQUIRED_USE="video_cards_fglrx ? ( !sna )" I some people might want this combination for eg. live cd.
> I some people might want this combination for eg. live cd. Why livecd need [sna] and fglrx?
The problem exists only for hybrid graphics systems, not for any other combination of Intel+AMD graphics. There are a number of use cases where a user would want to use the Intel graphics with SNA but still have the proprietary ati-drivers installed.
