Is that a X server error? System is LFS Linux

QEMU emulator version 2.9.92

Upgrade to version 5

Display is :0.0 but you used :0.1

No protocol specified

This sounds like an authentication error. X access is normally restricted with a cookie, mostly ~/.Xauthority or $XDG_RUNTIME_DIR/Xauthority. The path is stored in variable XAUTHORITY. X authentication is sometimes weakend with xhost. Current xhost settings can be seen with a blanc xhost command.

An often seen but bad solution is xhost + that disables X authentication entirely. If the user uid on host is the same as in image (e.g. with docker run option --user $(id -u):$(id -g)), a reasonable solution is xhost +SI:localuser:$(id -un). To allow root in container access to X, set xhost +SI:localuser:root.

A better solution is to provide a cookie to the container. It needs some preparation:

Cookiefile=~/mycookie
Cookie="$(xauth nlist ${DISPLAY} | sed -e 's/^..../ffff/')" 
echo $Cookie | xauth -f $Cookiefile nmerge -

Share file $Cookiefile with the container and set --env XAUTHORITY=/path/to/mycookie

This solved my issue ！ Many thanks！

1.set the right Display echo $Display to see the value on the host

2. run this scripts:

Cookiefile=~/mycookie Cookie="$(xauth nlist ${DISPLAY} | sed -e 's/^..../ffff/')" echo $Cookie | xauth -f $Cookiefile nmerge -

if not solved , just run xhost +

Thanks @mviereck for letting us know, should I change all xhost references to xhost +SI:localuser:"$(id -un)"?

[mviereck]

should I change all xhost references to xhost +SI:localuser:"$(id -un)"?

In fact, no. Your examples only share DISPLAY and /tmp/.X11-unix without caring for X authentication. (Edit: Just found you recommend xhost + in the troubleshooting section.) This works only if:

• Your display manager already sets up xhost +SI:localuser:"$(id -un)" on itself.

• The container user arch has the same uid as the host user.

  Check your output of xhost. I bet your user has an entry. Don't rely on this. If you run xhost -SI:localuser:"$(id -un)" (disabling) , you won't be able to run your own example. So your current example rather works "by accident".

xhost +SI:localuser:arch won't work because the host does not know this user name. Unfortunately, xhost does not accept an uid. xhost + disables X authentication at all and should not be used.

You can use xhost +SI:localuser:$(id -un) if you run the container with docker run --user $(id -u):$(id -g) [...]. Of course the container has to handle varying uids in that case.

I recommend not to use xhost at all but to set up a cookie. Cookies do not depend on user uids. This makes your setup a bit more complicated but clean.

(Advertisement: x11docker can do the job for you. ;-) )

[mviereck]

Unfortunately, xhost does not accept an uid.

I have to correct myself: It is possible to specify an uid instead of a name to xhost. Example: xhost "+SI:localuser:#1000" The uid must be preceeded with a #, otherwise it is interpreted as a name. That might be a solution for your setup. Specify the uid of container user arch.

You've been asked to add yourself to the docker group and not use sudo

How add myself to the docker group ?

Secondly, you're running kernel 5.3.7 and QEMU 2.9

@sickcodes @bhzhu203 Yesterday I wrote a wiki article on X authentication: https://github.com/mviereck/x11docker/wiki/X-authentication-with-cookies-and-xhost-(%22No-protocol-specified%22-error) It is not ready yet but already contains the most important parts for the issues discussed here.

[sickcodes]

Thanks a ton @mviereck I'll have some spare time at the end of this week, which I'll read everything if you've said so far and make security changes. :) so far changed the VNC password from mere hexadecimal to [:print:]

[jpmorrison]

I had similar errors and couldn't run docker over ssh with X forwarding. xterm worked though. I set DISPLAY=x.x.x.x:0 on the host since it's a local network and it worked (xhost + too).
