I've been struggling with this problem for a long time, on more than one distro, and finally I think I could trace the cause to VirtualBox.

I already joined kvm and pcscd groups to no avail.

This has been happening either with ArtixLinux and Gentoo hosts, running Windows 10 guest, but already happened also with a Windows 7 guest that I tested, hoping to stop the problem.

I really like VB and I've been using it for many years, but now it's becoming very stressing, saving my work every minute, never knowing when VB kicks me out to the login screen. It's becoming unbearable to the point of making me start searching for another virtualizing solution.

I wonder if someone can help me solve this nightmare, it would be much appreciated.

EDIT: Should I file a bug?

TIA

My crystal ball is foggy again today so some more information like Linux kernel version, VirtualBox version and log files (zipped) are needed.

To add to what Andy said, is this something that's reproducible? What crashes and under what circumstances?

Thank you for helping.

I guess the whole logs won't tell more than the extracts that I posted, but you know better:

messages.log: https://paste.pound-python.org/show/IpC ... aSRkbyEzE/
dmesg: https://paste.pound-python.org/show/ycA ... rTtR7wMFV/
xorg-session.log: https://paste.pound-python.org/show/XuA ... 1zzS2GubE/

Code: Select all

#uname -a
Linux mypc 4.14.14-1-ck #1 SMP PREEMPT Wed Jan 17 20:39:14 UTC 2018 x86_64 GNU/Linux

But it also happens with 4.9.76 either Artix or Gentoo

VB version: 5.2.6 r120293 with extensions and guest-additions same version

It's not exactly reproducible, I've been trying the whole morning and couldn't. But it happens, I would say always, when the guest VB window has focus, meaning, when I'm working on the guest. I don't think it ever happened with VB in the background.

Looking at the logs I've posted before, the X server crashes bringing down every graphic application using it, and I'm presented with the DM login screen, sddm in this instance. I've already tried with other DM's (lightdm, ...) and even just with startx, to no avail. I guess this rules out sddm.

Please attach the ZIPPED logs here, locally. Not a lot of people will go to 3rd party sites...

pound-python.org is one of the services advised by Gentoo for using the wgetpaste application.

People can check here, in case they trust the third party gentoo site

https://wiki.gentoo.org/wiki/Wgetpaste

Anyway, files are attached.

I have had this once, at the same I had other clients even not get that far. I would suggest to install the 5.2.7 guest additions and see if that helps..... It did with me

Thank you ChrisMW for helping.

I'm now on 5.2.6 but I'll try your suggestion. I guess it won't hurt to put guest additions one minor revision ahead.

Anyway, I'm now evaluating the cost/benefit of migrating the whole thing to kvm-qemu.
