X2Go crash from Mac/MATE to Fedora 25 w NIS user getting x2gostartagent: blocking creation of agent's keyboard file
This only seems to be affecting one user. He has a NIS account and has tried 2 NIS accounts to make sure. He's running a Mac with the latest X2Go (2.7.11) connecting to a Fedora 25 server with NIS, choosing the MATE desktop and audio disabled. We made sure to check the security settings as per this older post screenshot <http://lists.x2go.org/pipermail/x2go-dev/attachments/20151013/f02b140a/attachment-0001.png> and confirmed the .Xauthority permissions problem <http://lists.x2go.org/pipermail/x2go-dev/2015-October/010733.html> does not exist. Here are some debug-enabled logs.

I am not on a Mac, running Ubuntu with the very latest 4.0.0.1 nightlybuild x2go client and connecting to Fedora, and only Fedora also with the Mate desktop, nxagent cores on Fedora on a regular basis. I do not have this problem with Centos 6/7, Scientific Linux 6/7, all of which are Redhat releases, only with Fedora. Mint, Deb, and Ubuntu are all stable for me now, the only other OS I have issues with is OpenSuse and that because I can't run the latest release owing to the inavailability of a modern LibNX there.

Actually that's not entirely true when I say I am not on a Mac, I am ona Mac Pro 1,1 but it is running the 64-bit version of Ubuntu 16.10.

The X2Go client on his Mac desktop just goes black and kicks him out.
We have been working around it with XFCE and then using the work around for DBUS when the same user is logged in via ssh and X2go.

That would be the new black proxy window with the "X2GO" branding in dark grey letters, right? It's not a real crash, it just terminates? (I.e., OS X doesn't show an appcrash dialog.)
Normally, mate-session should start in there.
Maybe taking a look at ~NISuser/.xsession-x2go-errors might show something interesting.

So XFCE is working, while MATE is not?

I can't find a core and I did my best to make it crash but it does notseem to be in the mood tonight however dmesg did reveal this:
[168764.604757] x2goagent[2794]: segfault at c1 ip 000055fa1ed65ccc sp 00007ffedf8a7c40 error 4 in nxagent[55fa1ed22000+42f000]
This is on a mate spin of fedora-25 running in a KVM/Qemu virtual machineon i7-6700k platform. If I can find a core file I'll do a backtrace and forward it but did not find one in any of the directories I normally work in.

Difficult to say without knowing what to look for?
I've seen kgpg crashing in that log, but that may or may not be a problem.
The missing Composite and Fixes extensions are normal - you won't get any compositing effects, but that's okay.
Other than that, there's no major problem recorded in there.
This said, I've had a user on FC25 yesterday on IRC and he has reported problems with Emacs - which was built with GTK3 support. After he rebuilt it with GTK2, it started to work.
I also (ab)used him to test MATE and found out that mate-session is crashing upon start. Any GTK3 application crashes, basically, because of a bug in al ibrary used by GTK3 (libepoxy), that has been filed in Red Hats bugtracker for Fedora 24 already and fixed upstream for a while.
The root cause of that is that for some reason the GLX version is not reported correctly - instead a NULL pointer is thrown out. I don't see this behavior on Debian Jessie, which hints at a deeper problem with our nx-libs builds on Fedora 25 (and maybe even 24?)
I haven't yet been able to figure out why nxagent isn't doing what it should be doing, though.

Yes that emacs crash has been an issue for quite a while: https://bugzilla.redhat.com/show_bug.cgi?id=1349412 <https://bugzilla.redhat.com/show_bug.cgi?id=1349412>
Now I have a core dump to share with MATE and some logs from the server side. No errors under my user name but hope these are helpful:

With Fedora 25 it was working with Mate fine for me until very recently,as recently as February 7th. Then some update broke it. Because several things were updated simultaneously, x2go, mate, and libc, it is hard to know which was the cause but mate-session and many xfce programs all core with a segfault in libc.
I am now in the process of restoring the machine from a February 7thbackup and will update things individually to determine which broke.

I've seen kgpg crashing in that log, but that may or may not be a problem.
The missing Composite and Fixes extensions are normal - you won't get any compositing effects, but that's okay.
Other than that, there's no major problem recorded in there.
This said, I've had a user on FC25 yesterday on IRC and he has reported problems with Emacs - which was built with GTK3 support. After he rebuilt it with GTK2, it started to work.
I also (ab)used him to test MATE and found out that mate-session is crashing upon start. Any GTK3 application crashes, basically, because of a bug in al ibrary used by GTK3 (libepoxy), that has been filed in Red Hats bugtracker for Fedora 24 already and fixed upstream for a while.
The root cause of that is that for some reason the GLX version is not reported correctly - instead a NULL pointer is thrown out. I don't see this behavior on Debian Jessie, which hints at a deeper problem with our nx-libs builds on Fedora 25 (and maybe even 24?)

Please check the other messages to the thread, it looks like a MESA upgrade provoked these failures.

This might be the update to Mesa in Fedora
https://bugzilla.redhat.com/show_bug.cgi?id=1427174
A lot of programs won't start in my XFCE desktop under x2go. Even xfce4-terminal
The temporary fix is to downgrade mesa:
dnf downgrade mesa-libGL --allowerasing

Very useful information, thanks!
I had the user run glxinfo and on Fedora 25, he got the exact same message.
I wasn't able to reproduce it on Debian Jessie. There, glxinfo could query the GLX version information correctly and also reported working direct rendering via SGI 1.2/MESA 1.4 Gallium software renderer (or the like, I don't remember the specifics, but certainly not an error.)
Initially I thought this might be a problem with nx-libs. If it's really a bug in MESA, that would be good, because is a chance this problem can be fixed by fixing up MESA itself.

I applied all the upgrades, and downgraded mesa-libGL and everythingworked. Added the following to /etc/dnf/dnf.conf:
exclude=mesa-libGL
To prevent it from being upgraded until such time as that issue isresolved.

A lot of programs won't start in my XFCE desktop under x2go. Even xfce4-terminal
The temporary fix is to downgrade mesa:
dnf downgrade mesa-libGL --allowerasing
Very useful information, thanks!
I had the user run glxinfo and on Fedora 25, he got the exact same message.
I wasn't able to reproduce it on Debian Jessie. There, glxinfo could query the GLX version information correctly and also reported working direct rendering via SGI 1.2/MESA 1.4 Gallium software renderer (or the like, I don't remember the specifics, but certainly not an error.)

Do you have the same symptom? Is MATE not starting up at all? Or is it crashing after the session has been running for some time already?
Normally, core files tend to sit in the user's home dir - but that depends upon some circumstances (like whether creating core dumps at all is allowed or not - with different systems utilizing different methods of getting this to work.)
Fedora and RHEL-based distros use ABRT (Automatic Bug Reporting Tool), which stashes the core dumps and can easily send them to Red Hat's Bugzilla instance.
The general place to look at is probably /etc/security/limits.conf for core dumping permissions and then figure out what ABRT exactly does.
If you want to have ABRT out of the way, echo "core" > /proc/sys/kernel/core_pattern will take care of that.

Mate starts up and runs but it usually crashes when I'm opening a terminal, editing a file, or doing upgrades.
However there was a new x2goserver and some related files tonight thatinstalled during an upgrade and then after that a rather large update that involved 400 some packages and it didn't explode.
I poked about, opened terminals, vi'd files, etc, could not get it tocrash so not sure tonights update didn't fix it. If it crashes again and I can get a core dump, I will send a backtrace like I did for the problems I was having under Ubuntu.
Thank you very much for fixing those BTW.Normally, core files tend to sit in the user's home dir - but that depends upon some circumstances (like whether creating core dumps at all is allowed or not - with different systems utilizing different methods of getting this to work.)
Yes, that is where I usually find them but they were not in my homedirectory. I have to take a look at settings, might be the default has the core file size set to zero or turned off. I have not really changed much from the system defaults on that machine.

If it is a developer other than RedHat it will not. It will instead justpop up a message telling you such and such crashed and is not a RedHat product and if you want it fixed to contact the developer.

LXDE and XFCE kind of work which is to say the desktops come up but in LXDE applications except for the action button aren't working, however this may be because they aren't fully installed, and XFCE seems to be missing a lot of it's components, ICEWM works, kde isn't installed, gnome isn't installed. This was the mate spin of fedora and was mostly the system defaults.
Although the core is on mate-session, it WAS working before tonights updates and they did not include update for mate. I can not test the machine locally because it is a virtual machine running under KVM/Qemu.
If you want to have ABRT out of the way, echo "core" > /proc/sys/kernel/core_pattern will take care of that.
Yes, did that which is how I got the core. I still have it if you wouldlike to examine further.
I installed every other desktop available and the only one that workedproperly was icewm.
Mihai
For what it's worth I applied same updates to a Ubuntu 16.10 machine andthings still worked with Mate afterwards.

Although the core is on mate-session, it WAS working before tonightsupdates and they did not include update for mate. I can not test the machine locally because it is a virtual machine running under KVM/Qemu.
If you want to have ABRT out of the way, echo "core" > /proc/sys/kernel/core_pattern will take care of that.
Yes, did that which is how I got the core. I still have it if you wouldlike to examine further.
I installed every other desktop available and the only one that workedproperly was icewm.
