Description Sebastian Pipping gentoo-dev 2018-03-11 16:59:58 UTC
I'm still researching the very cause of this problem so the summary in the title may still change.  The symptom was, that after upgrading a number of packages, when logging in to an XFCE 4 session, I would be dropped right back into the log-in manager with lines like

  [   24.976424] xfsettingsd[6648]: segfault at c ip 00007f6bc7ec4de0 sp 00007ffe3060c188 error 4 in libxcb-glx.so.0.0.0[7f6bc7eb8000+19000]

in dmesg output, for xfce4-session and xfce4-panel and so on as well.

I'm severity to critical because it took me multiple hours to be able to log back into my X session.
Comment 1 Sebastian Pipping gentoo-dev 2018-03-11 17:49:16 UTC
Further analysis confirms the issue for:
* XFCE 4.12 and XFCE 4.13
* Mesa 17.3.6 and 18.0.0_rc4
* libxcb 1.12-r2 and 1.13

So x11-base/xorg seems indeed to be the issue here.

A have the same! (on system with newest ~amd64 packages)
But only trying to log-in after logging-out.
xdm restart allows me to log-in again.
Comment 4 Lars Wendler (Polynomial-C) (RETIRED) gentoo-dev 2018-03-12 10:28:14 UTC
Considering that other desktop environments like KDE and Gnome seem to work fine, adding this mask IMHO is a drastic measure...
Comment 5 Thomas Beinicke 2018-03-12 10:45:17 UTC
I seem to have the same problem with kde.
The only reason I could login to KDE every time was to completely disable plasmashell and use "liquidshell" inside kde.

Also using intel via modesetting driver.
Comment 6 Lars Wendler (Polynomial-C) (RETIRED) gentoo-dev 2018-03-12 12:08:37 UTC
Sebastian, what graphics device and driver do you use?

I dared to go for it due to damage it does to users.  It's totally up for discussion, just a start, I'd be happy to get it back safely some way.

So two reports from intel users. 
I have no issues with this xorg-server version neither with latest xf86-video-ati nor with latest xf86-vide-amdgpu (both running kde).

Fair enough, let me try with intel downgraded to 2.99.917_p20171018 and xorg-server back at 1.19.99.901-r1.

Same issue with 2.99.917_p20171018 (that has been well with previous Xorg for me since October).
Comment 11 Matt Turner gentoo-dev 2018-03-13 00:11:45 UTC
REALLY NOT OK to unilaterally mask a package just because you have a bug.

Have you filed an upstream bug? Please do so.
Comment 12 Alexander Sergeyev 2018-03-13 07:09:22 UTC
I have intel graphics too, but with i3wm and with X started via startx from a virtual console. The libxcb-glx.so library is used by firefox, according to /proc/$pid/maps. So far I've got no problems, let alone crashes.

Comment 13 Massimo Burcheri 2018-03-13 09:01:10 UTC
All last xorg-server versions have been working with Xfce:  1.19.5  1.19.6  1.19.6-r1  1.19.99.901  1.19.99.901-r1. Yesterday  1.19.5-r1 was breaking Xfce. Going back to 1.19.99.901-r1 makes Xfce start again but still has graphic errors on some panels. It's radeon graphics.

> REALLY NOT OK to unilaterally mask a package just because you have a bug.

I didn't mask it for me: a local mask is way less work than opening a ticket and masking things in Git, for me.  I masked it to save others hours to unbreak their X session.  I'm happy with any way the X11 team decides to deal with the mask and the problem.

This issue is not trivial. The strategy of Sebastian and the fact that the mask had already arrived in the tree when I encountered the breakage, that all saved my working day.

Graphic errors are rather caused by fontconfig, https://bugs.gentoo.org/650248#c9.
Comment 17 hkBst 2018-03-16 10:55:46 UTC
I have no problem running x11-base/xorg-server-1.19.99.901 with xfce4 and lxdm-0.5.3-r1 on

00:02.0 VGA compatible controller: Intel Corporation HD Graphics 520 (rev 07)
	Subsystem: Hewlett-Packard Company HD Graphics 520
	Kernel driver in use: i915

, though logging out (and back in) is not something I generally do or have tried yet with this setup.

x11-base/xorg-server-1.19.99.901::gentoo was built with the following:

Comment 18 Lars Wendler (Polynomial-C) (RETIRED) gentoo-dev 2018-04-04 07:10:43 UTC
I've added x11-base/xorg-server-1.19.99.903_pre to poly-c overlay and would like people having issues with xorg-server-1.19.99.901 to test that version and report back if they still have issues. Don't be confused by the "_pre" in the version. I simply use it to make the version in my overlay lower than the same version on ::gentoo (once it got added there).
Comment 19 tka 2018-04-15 20:34:39 UTC
I tested xorg-server-1.19.99.904 (copied the xorg-server-1.19.99.901-r1 ebuild and removed the randr patch). I build xorg-server-1.19.99.904, restarted X, and built media-video/vlc (vlc's test suite reliable triggered the segfaults for me). No segfault, looks good.

Then, I downgraded to xorg-server-1.19.99.901-r1, restarted X, build vlc, and
> vlc[14227]: segfault at c ip 00007f1721e76db3 sp 00007f16e9ba6440 error 4 in libxcb-glx.so.0.0.0[7f1721e69000+20000]

So to confirm the result, back to xorg-server-1.19.99.904. Rebuilt vlc and no segfault. So the problem seems to be fixed in 1.19.99.904.
Comment 20 Matt Turner gentoo-dev 2018-04-15 23:05:24 UTC
Thanks!

I've pushed 1.19.99.904 into the tree. It's still masked until sping gives the go ahead.

Please test and confirm it works.

Please try 1.20.0. When you added the package.mask you took the responsibility of testing fixes.
Comment 23 Derk W te Bokkel 2018-05-11 12:59:34 UTC
I'm not sure but bug 653744 may also be a manifestation of this bug..
perhaps xfwm4 (gtk2) is the culprit xfwm4(gtk3) git based build appears to work.
Just extra info for consideration
Comment 24 manwe 2018-05-11 16:20:02 UTC
I've just tested xorg-server 1.12.0 and it breaks xfwm4 with --composite=on (I'm not using whole xfce, just xfwm). With --composite=off it works fine, but with =on whole screen turns white. There are windows below, I can see mouse cursor changing while hovering over them. Intel HD 4600, everything up to date from ~amd64 tree.

No crashes with 1.20.0 with XFCE for me.

I have xfce-base/xfwm4[xcomposite] around and just enabled "Composite" mode in Xfce WM Composite Editor for the first time.  See shadows now, seems to work for me.  Is that the same thing that's broken for you?
Comment 26 David Heidelberg (okias) 2018-05-13 20:02:34 UTC
GUYS, so 1.20.0 is masked for everyone due to some unspecified crash with Xfce for "some" users? No debug info, no upstream report (xfce or xorg)?

as @mattst88 says, it's no reason to mask it (not saying it's bugless)..

Please unmask, it's Gentoo, not Debian stable...
Comment 27 Greg Turner 2018-05-13 22:09:10 UTC
The particular reason for this mask's creation might have been overly conservative, but have you guys seen this?:

https://lists.x.org/archives/xorg-devel/2018-May/056913.html

I can't even remember the last time there was a major xorg-server release... can you?  Pretty sure it's been a good while.  I know we're running ~amd64 and sometimes stuff is just going to happen but... this particular update seems like the type of thing very, very likely to catch a good number of desktop users unaware and really mess their day up.

Has there been some serious assessment as to how much trouble this particular update is likely to cause across the Gentooverse?  Xorg really ought to be treated with kid gloves like portage, pid-1 and toolchain packages, shouldn't it, so we don't make everybody miserable even if they technically could/should have known better?

OK, I should have kept reading.. the above was just the user doing --enable-dri1 across the affected drivers which looks like the default in xorg-2.eclass.  

Anyhow my point wasn't really about that particular thing; just a general note of caution: I see no urgent need to rush into unmasking the release until there's a sense that most things work for most users...  Those eager to jump onto the latest can always unmask it in /etc/portage.

By the way I hope none of this sounds like I'm assuming the X herd hasn't done their job or something... frankly I have no idea what their process looks like but I'm sure they do plenty of work behind the scenes that I've benefited from in blissful ignorance :)
Comment 29 Mike Lothian 2018-05-23 12:29:24 UTC
Has anyone reported this upstream?

I had a lot of issues with the pre-release of Xserver 1.20, including one that was really a Mesa bug, but they've been fixed now
Comment 30 Alex Bennee 2018-06-06 08:20:40 UTC
I'll add that on my SynQuacer I was hardly able to log in due to triggering nouveau bugs. Since unmasking the latest xorg for my system it's a lot more stable.

Posting from LXDE as XFCE with the new xorg-server-1.20 is showing me the white screen manwe also mentioned and is unusable.

Comment 34 hkBst 2018-06-16 15:37:20 UTC
Recompiling xfwm4 did not help. Recompiling without xcomposite runs into a compiler error:

display.c:612:19: error: ‘ScreenInfo {aka struct _ScreenInfo}’ has no member named ‘output’

Sticking to LXDE for now, but let me know if there is anything else I can try!
Comment 35 tt_1 2018-06-16 15:43:26 UTC
You def should open a new bug for the compile failure, and also consider to speak with upstream too in case they are unaware of it.
Comment 36 hkBst 2018-06-22 07:36:15 UTC
Please reopen...

> Please reopen...

Please open a new bug, since I think this is a different bug from the one originally reported. The original reporter confirmed his was fixed.
Comment 38 hkBst 2018-06-23 09:19:33 UTC
Very well: bug 658810.
