[Bug 1562219] [NEW] xinit will not work as non-root.

[Adam M]

Public bug reported:

When attempting to run xinit or startx after upgrading from 14.04 to
16.04 it will not work. There seems to be some sort of permission
issue. I have seen another person with this issue as well here:

http://askubuntu.com/questions/749370/ubuntu-16-04-xf86openconsole-
cannot-open-virtual-console-2?newreg=ba376d7a182d44608ed4675346b1ed74

An example is when attempting to launch kodi, which worked prior to the
upgrade:

xinit /usr/bin/kodi --standalone -- -nocursor :0

I have tried numerous workarounds including reinstalling xorg, removing all x-related files in my profile, and creating a new user. Unfortunately none of these worked.

«sudo chmod 0660 /dev/tty*» worked for me until reboot. Changing
permission in udev rules for tty to 0660 from 0620 could be a temporary
fix.

There is a workaround. See:

Specifically:

5 Add a new systemd script

And everything under it.

I am affected by the same bug, although the X error message is slightly
different ("parse_vt_settings: Cannot open /dev/tty0" instead of
"xf86OpenConsole: " ...)

In /etc/X11/Xwrapper.config I have tried to replaced

allowed_users=console

with

allowed_users=anybody

and in this file I also tried the option

need_root_rights = yes

but both attempts had no visible consequences.


I have looked at the workaround for koda posted above, but I am unable to extract the bits that may make it help in my case. Perhaps someone can give suggestions to me based on the posted workaround. The program I want to run in its own Xserver is a game, so all the systemd stuff in the workaround is not that relevant to me. Although my knowledge of X is very limited, I'd love to contribute with some testing as far as I can go. Thanks for your time and efforts /Mikkel.

Hi again.

Seems that my case is connected to my NVIDIA card and this bug:

https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1525735

The following solved my problem:

sudo apt install xserver-xorg-legacy

In /etc/X11/Xwrapper.config I replaced

allowed_users=console

with

allowed_users=anybody

None of workarounds worked for me.

Omg, is there a single thing which 14.04 → 16.04 upgrade didn't break?
Sad to see that distro widely recommended for newbies slowly drowns
under a bunch of architectural, planning, and software problems, which
are hard to fight even for long time users. Perhaps since now we should
recommend Fedora instead.

I found a simple solution for this issue. Start x server as root and
then start windows manager as regular user.

1. sudo Xorg &
2. export DISPLAY=:0.0
3. bash .xinitrc

I don't know if it is real workaround but if you want to avoid running X
as root you can

1. Go to one of tty1-tty6 and login as a normal user
2. run the server in the same tty you logged in, e.g. for tty6:

xinit /usr/bin/openbox -- :1 vt6

Tested on ubuntu mate 16.04.

The workaround is not working :( -

$ sudo setfacl -m u:kodi:rw /dev/tty0 /dev/tty7
setfacl: Option -m: Invalid argument near character 3
$ sudo chmod 0660 /dev/tty*
$
$ startx
...

Any ideas?

I've tried for an hour, but can't seem to get any fix working. Highly
frustrating as I just switched my laptop from Debian to Ubuntu, and now
I have to spend time switching it back again.

Comment #16 seems to misunderstand the bug. Likewise the workaround in
comment #12 might possibly work for some people, but there appear to be
several of us who rely on running X as a non-root user.

This is not something that I would have expected to be broken. Is there
any update on this? It's been a while since anyone commented on it, and
the bug doesn't appear to be assigned to anyone.

I can confirm that #14 works for me also, however it doesn't provide me
with with the functionality that I require.

It would be useful to know whether this is intended behavior, or an
unintended bug.

Updated bug title to reflect comment #14, and added a paragraph to the
top of the bug description outlining the issue as it is currently
understood.

** Description changed:

+ If as an unprivileged user you launch xinit (or startx) to any vt (EVEN
+ IF UNALLOCATED BY SYSTEMD) it will fail as described below. The only
+ exception appears to be if the vt you attempt to launch X onto is
+ already logged into by that user. For many this makes running X
+ unprivileged unworkable.

When attempting to run xinit or startx after upgrading from 14.04 to
16.04 it will not work. There seems to be some sort of permission
issue. I have seen another person with this issue as well here:

http://askubuntu.com/questions/749370/ubuntu-16-04-xf86openconsole-
cannot-open-virtual-console-2?newreg=ba376d7a182d44608ed4675346b1ed74

An example is when attempting to launch kodi, which worked prior to the
upgrade:

xinit /usr/bin/kodi --standalone -- -nocursor :0

Ubuntu 16.04, Nvidia Quadro 1000m, #14 allow the X server to run, applications may be launched (xterm, then xclock) and they appear in ps, keyboard input to the xterm works, but the display is totally black. No errors are in the ~/.local/share/xorg/Xorg.1.log file (a failure does show:
xf86EnableIOPorts: failed to set IOPL for I/O (Operation not permitted)
but that appears in the working :0 display log also. Running as root has same result, black display on the vt. There may be several issues here.

On another 16.04 machine without Nvidia, comment 14 produced a working
display. The Nvidia driver causing the problem on the first machine was
367.57.

Comment 14 works with Nvidia when using the nouveau driver, but not the Nvidia driver 367.57 (black screen). Starting an xterm allows you to run other things, even unity.
Using the nouveau driver, login to vt2 and run:
xinit /usr/bin/xterm -- :1 vt2
Result is a white background xterm, fully functional when cursor is over it.

Ubfan1's comments (#19, #20 and #21) are not relevant to the bug as it
has been described. We were already aware that X sessions could be
started on the same vt as the command line that they're launched from.

Further complications from the Nvidia driver would seem to be a separate
bug?

As the bug forces X to be run with escalated privileges, I would
categorise it as a SECURITY bug (which would raise it's BUG HEAT score).
However I am not aware of how this is accomplished. I hope that someone
will review and comment on this suggestion.

Me too. Under 16.04, 64 bit, with openbox, startx (or xinit) as user
fails. Sudo startx gives me a console with a tiny font, so apparently it
starts X but not Openbox. I'd explore that further and probably find how
to start Openbox, but I don't want to run X as root anyway. I just tried
sudo as a diagnostic experiment.

I have another 16.04 64 bit system on the same machine using lighdm.
That does boot and run openbox. That sys has OTHER problems I won't go
into here, but it does prove the problem lies with xinit. Given all the
OTHER problems with it, it also proves that 16.04 wasn't ready for
release at all, let alone as an LTS. Maybe Canonical needs to reconsider
the release-on-schedule policy and instead wait until they get through
the alpha stage.

I should add that this probably the 5th or 6th time I've installed a
16.04 system on this machine and failed to get startx to work properly.
I have another such that I haven't scrapped yet that WILL eventually
start openbox in response to startx. But it takes a long time and
results in my being logged in on ALL available ttys with most of them
showing error messages about xserver failure.

Uh, I wish I could edit my 2 posts above out. My problem was simple.
After installing from the mini.iso, I was running an installation script
that has a command of the form:

sudo apt-get install --no-install-recommends package1 package2 package3
. . .

It always worked before. But one of those packages no longer exists and
apparently apt-get just doesn't anything on a list like that when ANY of
them are missing. There was an error message but it only refered to the
one package so I falsly assumed it was getting the others. So I didn't
have openbox. Duh.

As for my post #14,

1) It was tested on Intel HD Graphics 3000 (only open-source drivers are
available for this hardware)

2) One should launch a separate dbus instance when starting X. Without
it, steam client, especially in big picture, mode stutters:

xinit /usr/bin/dbus-launch --exit-with-session /usr/bin/openbox-session
-- :1 vt6

If I could edit posts, I would add this information on September. Sorry
folks.

3) I've tested it also on proprietary Nvidia drivers (367.57) on my
desktop (only few minutes). It seems the same issue is here; without
dbus-launch instance, steam client in big picture works improperly. With
the dbus, it seems to work flawlessly.

This bug drove me batty until I found this. Making a Nextcloud appliance with Ubuntu Server 16.04 as the OS and I couldn't install a gui. Tried xfce, lxde, and lxqt to no avail. Re-installed, tried again, and nothing.
Post #14 worked for me but a little different.

startxfce4 -- :1 vt1

Is the proper command to launch xfce once logged on.

The workaround I used to fix the original problem as stated by the
person who opened this ticket was to do the following:

chmod ug+s /usr/lib/xorg/Xorg

It seems in Ubuntu 14.04 the Xorg xserver binary has permissions of:

-rwsr-sr-x 1 root root 10192 Dec 9 2014 /usr/bin/X

so by running the above chmod command on the 16.10 (what I have
installed) installed xserver binary does indeed fix the original
poster's issue.

no, the workaround should be to install xserver-xorg-legacy, which
installs the suid-root wrapper again

#29 does not seem to be correct, at least in my case. Installed xserver-
xorg-legacy first, and checked. No 'X' wrapper binary present. After
installing other xserver packages, this is what I have.

Output of ls -la /usr/bin | grep X
On 14.04:
-rwsr-sr-x 1 root root 9532 Dec 9 2014 X
lrwxrwxrwx 1 root root 1 Jan 3 2013 X11 -> .
-rwxr-xr-x 1 root root 2322928 Oct 13 09:07 Xorg

On 16.04
lrwxrwxrwx 1 root root 4 Oct 13 08:59 X -> Xorg
lrwxrwxrwx 1 root root 1 Mar 4 2016 X11 -> .
-rwxr-xr-x 1 root root 274 Oct 13 08:59 Xorg

No matter what I do, including trying --force-overwrite passed to dpkg,
it installs a link to Xorg, not the suid wrapper.

Update to #30 Upon further investigation
On 14.04, the files in /usr/bin are binaries.
-X is a suid wrapper binary
-Xorg is the actual binary

On 16.04, they are scripts.
-X is a link to Xorg
-Xorg is a script, calling the actual executables in /usr/lib/xorg/.

It seems the Xorg script in /usr/bin should check if the binary wrapper
"Xorg.wrap" is present in /usr/lib/xorg. If it is, act as a suid wrapper
and use /etc/X11/Xwrapper.config as it's config file(according to the
man page for Xorg.warp), otherwise exec /usr/lib/xorg/Xorg directly.

So it seems the problem is that the legacy package is not installing the
Xorg.wrap binary (perhaps in only some cases???) as many users report
editing Xwrapper.config has no effect.

Also, dpkg -S Xorg.wrap shows no matches suggesting this may be an
oversight?
