Failed in starting with `--weston-xwayland` #19

netsgnut · 2017-12-10T07:16:49Z

Hi,

Thanks for the x11docker project! On my Ubuntu 17.10 box that is running on Wayland session, I have got errors with the flag --weston-xwayland. --xephyr seems to run fine.

Have run with --verbose and got the following as the resulting log. Do you have any ideas/pointers on what could be the culprit? Thanks.

x11docker: Sun Dec 10 07:06:21 GMT 2017 Ubuntu 17.10 
Command: /opt/x11docker/x11docker --weston-xwayland --desktop --gpu --  x11docker/mate 
Parsed options:  --weston-xwayland --desktop --gpu -- '' 'x11docker/mate '

x11docker WARNING: Option --gpu degrades container isolation.
  Container gains access to GPU hardware.
  This allows reading host window content (palinopsia leak)
  and GPU rootkits (compare proof of concept: jellyfish).

x11docker note: Hardware acceleration (option --gpu) works quite well with open
  source drivers (radeon, nouveau, intel ...) on host and OpenGL/MESA in image.
  If you have closed source drivers on your host, you need to install
  the very same driver version in your image to get hardware acceleration.

It is a bit strange as weston does not show an obvious error message. It just stops during startup. On my debian system, it starts up well in Gnome-Wayland.

Does weston start if you run it alone in a terminal?

Looking closer, I see weston tries to load extension EGL_KHR_platform_mir. Maybe the issue lies here. MIR was an Ubuntu project similar but incompatible to Wayland.

I did a change to x11docker to use Xwayland backend instead of Wayland to create its window if it runs on Ubuntu. Please try out if this solves the problem: https://raw.githubusercontent.com/mviereck/x11docker/experimental/x11docker

netsgnut · 2017-12-11T05:04:14Z

Thanks @mviereck! Applying the patch as specified above (v3.8.1) does allow calling x11docker --weston-xwayland --desktop --gpu -- x11docker/mate successfully. indeed it is pretty strange without any error message in the console.

Does weston start if you run it alone in a terminal?

...and a weston window will appear.

Looking closer, I see weston tries to load extension EGL_KHR_platform_mir. Maybe the issue lies here. MIR was an Ubuntu project similar but incompatible to Wayland.

Indeed. On a potentially unrelated note, if I run weston alone I would get a segfault.

While it seems to work for now, feel free if you need any more test here as well - my dev box is an Ubuntu 17.10 (artful), upgraded from a fresh installation of 17.04 (zesty). Thanks again!

…ce-wine-#1) # 10.12.2017 V3.8.1 bugfix Ubuntu: avoid Wayland backend for Weston due to MIR issue #19 # --xorg: change Xorg to X. X is setuid wrapper for Xorg on Ubuntu 14.04

Fine that it works now and the solution was that easy. :-) Thanks for reporting, I would not have found that issue myself.

The bugfix is quite small, weston now runs as an X client instead of running as Wayland client on Ubuntu. Though, I prefer it to run as Wayland client as that adds another layer of security. Hopefully the bug will be gone in Ubuntu 18.04.

Strange that weston does not crash if running as root. As user, it will most probably run on your ystem withweston --backend=x11-backend.so.

Thanks! Currently I don't know anything special to test. Just try out x11docker options and report if something seems to be fishy.

A new option that may fail in Ubuntu is --systemd. It allows containers to run with systemd as init system (systemd must be installed in image). --systemd depends partially on the host, and as Ubuntu is migrating from Upstart to systemd, there may be unexspected issues. Maybe you would like to try that out? An example image is x11docker/cinnamon.

I already found that Ubuntu images do not work well with --systemd, it seems the migration is not complete yet.

I have uploaded the patch / V3.8.1 yet.

Thanks! I tried the final v3.8.1 release and ran it with --systemd --weston-xwayland for x11docker/cinnamon, it seems to be running fine. Even --sys-admin seems optional here.

There is one more thing that bothers me but may not be entirely related to this issue at all - my apologies if I should file a new issue or we should dismiss it as expected behavior.

When running x11docker with Mate or Cinnamon, with flags --hostwayland or --weston (but not together), I would receive an error Could not connect to session bus: Failed to connect to socket /tmp/dbus-xxxxxxxxxx: Connection refused. With --xwayland alone, however, I would get a "passthrough" window-less interface that does not accept any input and would simply give focus to the window behind it. Are both of this intended behavior?

Thanks again. Admittedly I know too little regarding the X/Wayland/compositors under the hood than I should. Would like to have your pointers here, if possible.

It is better to open new issues ;-).

I would receive an error Could not connect to session bus: Failed to connect to socket /tmp/dbus-xxxxxxxxxx: Connection refused.

I am currently working on a major update that will set up dbus, consolekit and /tmp/.ICE-unix properly. Most probably this error message is related. Though, I do not get exactly the message you describe. Would you mind to open a new issue and show me the exact command you have used? Also it helps to store x11docker.log at https://pastebin.com/ . You find the logfile after terminating the x11docker session in ~/.cache/x11docker/x11docker.log. Though, I doubt mate or cinnamon will run in a pure wayland environment at all.

With --xwayland alone, however, I would get a "passthrough" window-less interface that does not accept any input and would simply give focus to the window behind it.

I am not sure if I understand correctly. Xwayland appears as a borderless window in wayland; mate and cinnamon should start properly in Xwayland. The Xwayland window itself can be moved around with META+LeftMouseButton. Please open a new issue for this if you experience a different behaviour.

OK, thanks :)

Will try to provide better description for each of them after gathering more information first then. Thanks again!
