[Bug 1652282] Re: Xwayland not using XAUTHORITY, prevents root applications from connecting
I'm only recently familiar with the Mutter design, but... Mutter is the graphics platform on which gnome-shell is built. Mutter supports running under a Xorg server, or none at all on bare metal (Wayland mode). So in order to provide a seamless consistent interface in the latter case it spawns Xwayland, which allows X apps to work with Wayland even when Mutter's not running on Xorg. In this way, any shell built on Mutter has the option to use Xorg or Wayland, and if using Wayland can still transparently run X apps. "Clutter" is the graphics toolkit on which Mutter is built. "Cogl" is the graphics toolkit on which Clutter is built. Cogl uses OpenGL directly. Yes, that's probably too many layers but that's how things evolved. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1652282 Title: Xwayland not using XAUTHORITY, prevents root applications from connecting To manage notifications about this bug go to: https://bugs.launchpad.net/gdm/+bug/1652282/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Ohh... I thought it was an alternative light weight compositing window
manager similar to compiz. Or was that clutter?
I'm not sure why taking care of spawning Xwayland would be in the
compositing graphics library.

Phillip,
Mutter is not just a binary, but is also the library which provides ALL
the graphics for the login screen and gnome-shell. So yes Ubuntu does
use mutter for everything :)
If your Wayland login option has gone missing then that means the
Wayland backend ("eglnative") of mutter had crashed during startup and
so has been disabled. Please log a NEW bug for that by running:

Ubuntu doesn't use mutter by default though ( is that what lubuntu uses? ). I looked at this again today and for some reason gdm isn't giving the option to log in with a wayland session. I switched to lightdm and it appears to not bother with Xwayland and just runs gnome-shell, and gnome-shell in turn spawns Xwayland, so *it* needs patched to add XAUTHORITY too. ** Also affects: gnome-shell (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1652282 Title: Xwayland not using XAUTHORITY, prevents root applications from connecting To manage notifications about this bug go to: https://bugs.launchpad.net/gdm/+bug/1652282/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1652282] Re: Xwayland not using XAUTHORITY, prevents root applications from connecting
It has been widely publicized at least since Fedora 25's release a year ago that GNOME on Wayland does not support running GUI apps as root. It has long been best practice for apps to not do this. Instead of trying to implement clever workarounds, app developers should follow best practice here. Would you like to submit a patch for sudo? The GDM maintainer Ray Strode rightfully believes that it is wrong (i.e. Won't Fix) to have XWayland support running apps as root as long as Wayland does not. Therefore, someone will need to have a proposed fix for that issue first before worrying about XWayland. At this point, I don't believe that Ubuntu intends to diverge from upstream on this issue, so to some extent, Won't Fix is appropriate here too. So fix things upstream instead of complaining to Debian and Ubuntu. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1652282 Title: Xwayland not using XAUTHORITY, prevents root applications from connecting To manage notifications about this bug go to: https://bugs.launchpad.net/gdm/+bug/1652282/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

No, it is NOT the new standard since as I have said, wayland apps have no issue running as root. Applications will NOT be totally rewritten to split off the parts that need root into a separate program. YOU stop changing the title, YOU are being a nuisance: this does not just affect gparted. In fact, gparted has now worked around the issue by automatically running xhost to fix the broken configuration. Jeremy, you can easily see it is true by simply suing to root and running any native wayland ( gdm3 ) application ( like gedit ). It works just fine.

[Bug 1652282] Re: Xwayland not using XAUTHORITY, prevents root applications from connecting
@Phillip, I am afraid that this is the new standard and it's not going to change. Just use Xorg if you don't like it. But anyway, soon applications will all upgrade their source code, and then when they meet the set requirements they will all work as before. Just more securely. So please stop changing the title. You're just being a nuisance. ** Summary changed: - Xwayland not using XAUTHORITY, prevents root applications from connecting + GParted does not work in GNOME on Wayland -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1652282 Title: Xwayland not using XAUTHORITY, prevents root applications from connecting To manage notifications about this bug go to: https://bugs.launchpad.net/gdm/+bug/1652282/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1652282] Re: Xwayland not using XAUTHORITY, prevents root applications from connecting
I am afraid that this is a Wayland security feature and that it is not going to be removed just because some users don't like it or don't understand why it is there. As a workaround you can just carry on using Xorg, but under Wayland the program has to be adapted in order not to run the whole program and GUI as root but rather just the specific things within it that need that. I'm not sure that there actually is anything the Ubuntu people can actually do about this though unless they hack at Wayland and make it less secure. If you want to change Wayland then file an upstream report about this. Ubuntu is really just packaging and redistributing this stuff. ** Changed in: gparted (Ubuntu) Status: Invalid => Confirmed ** Summary changed: - Xwayland not using XAUTHORITY, prevents root applications from connecting + GParted does not work in GNOME on Wayland ** Tags added: yakkety ** Description changed: - When running wayland, GDM fails to set up an XAUTHORITY file and instead - relies on the process UID for authentication.

It is a shame that you are unwilling to make a simple configuration change to prevent a completely broken experience for your users. People get very frustrated when they try to open an application and nothing happens. No error message; nothing. All because of a silly default policy.

[Bug 1652282] Re: Xwayland not using XAUTHORITY, prevents root applications from connecting
@Dave Stroud, If you spend a few minutes to create/install/modify some file(s), for example 'gks' according to my previous comment, you need not type 'xhost si:localuser:root' every time you boot up. 1. Some of us think that this is an unnecessary complication or worse, 2. Some of us think that it is an important step to increase the security, to prevent GUI programs to run with elevated permissions. The developers of Wayland belong to the second group ;-) -o- I think that the main linux distros will gradually adjust to the opinion of their users ... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1652282 Title: Xwayland not using XAUTHORITY, prevents root applications from connecting To manage notifications about this bug go to: https://bugs.launchpad.net/gparted/+bug/1652282/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

(xhost si:localuser:root) Is a work around I found on fedora forum. Only problem is it has to be used every time you boot up.This is happening with any program that uses root.
