Keyboard don't work on Chromium when started with nsdo

[vstoykovbg]

I run Chromium like this:

nsdo tornamespace1 /usr/bin/chromium-browser --temp-profile --incognito

And can't use keyboard with chrome (can't type URL, etc.).

valentin@computer:~$ nsdo --version
nsdo version 1.0

I am using Gnome with Xwayland. Also tested it with Gnome/Xorg, Unity and Ubuntu - the same.

However, it works with Fluxbox.

...

After I logged out/logged in multiple times (while testing with different graphical environments) it started to work and now I can type the URL in the Chromium. So, in order to reproduce this bug you need to start with a fresh home directory.

Also, TOR was shut down during the tests. I started it within byobu, so it should not shut down between logouts... Strange.

That's pretty spooky 👻, I just upgraded to Debian buster which has Wayland by default now apparently(?), so I'll have to try this out

Accidentally pressed close button I'm not good with computers

[vstoykovbg]

Today it does not work (Gnome/Xorg). I don't know how I managed to make it work the last time.

Logged out and logged in with Fluxbox - works. Logged out and logged in with Gnome/Xorg - does not work.

It prints these error messages when pressing keys:

I managed to run nsdo tornamespace1 /usr/bin/chromium-browser --temp-profile within Xephyr (running Fluxbox within it) and I am using this as a workaround (I can type normally this way).

[vstoykovbg]

Also other apps don't react on keypresses. For example, LibreOffice:

valentin@computer:~$ soffice

(soffice:22579): dbind-WARNING **: 14:47:55.306: Couldn't connect to accessibility bus: Failed to connect to socket /tmp/dbus-YXHbxMw69l: Connection refused

(soffice:22579): IBUS-WARNING **: 14:48:00.496: Unable to connect to ibus: Could not connect: Connection refused

(soffice:22579): IBUS-WARNING **: 14:48:07.816: Events queue growing too big, will start to drop.

...

I made some tests and it looks like removing some of these variables make the programs accept keystrokes:

unset DBUS_SESSION_BUS_ADDRESS 
unset XMODIFIERS 
unset GTK_IM_MODULE
unset QT_IM_MODULE

For LibreOffice and Chromiub-Browser it's enough to only unset GTK_IM_MODULE.

Before removing the variable:

valentin@computer:~$ echo $GTK_IM_MODULE
ibus
valentin@computer:~$ 

[ausbin]

Sorry, I'm pretty late here but I can reproduce this with Firefox, thanks for the report. Example:

$ DBUS_SESSION_BUS_ADDRESS= nsdo gatech firefox --no-remote -P gatech # can type
(firefox:42273): IBUS-WARNING **: 23:58:39.625: Unable to connect to ibus: Could not connect: Connection refused
$ nsdo gatech firefox --no-remote -P gatech # can't type
(firefox:42716): IBUS-WARNING **: 23:59:07.867: Unable to connect to ibus: Could not connect: Connection refused
(firefox:42716): IBUS-WARNING **: 23:59:10.716: Events queue growing too big, will start to drop.

I believe this happened to me a few years ago, and the solution was to connect to dbus over a non-abstract unix socket instead of the default abstract unix socket. Looks like I upvoted this post which seems to confirm that: https://unix.stackexchange.com/q/184964/62375

I think I did something a little crazy like recompiling dbus, but jeez I can't remember. Will have to look into this when I get a chance

[workdesk96]

Temporary work around for the keyboard issue seems to be to use sudo within the namespace.
For example, in case of waterfox browser:

nsdo gatech bash

Then within that bash shell

sudo -u <linux-user-name> ./waterfox

[pymen]

for me it was enough to have min setup as

# fish
env DBUS_SESSION_BUS_ADDRESS= nsdo <yourns> google-chrome
# bash
DBUS_SESSION_BUS_ADDRESS= nsdo <yourns> google-chrome

but AI suggests like this (which also works)

#!/bin/bash

export GTK_IM_MODULE=xim
export QT_IM_MODULE=xim
export XMODIFIERS=
unset DBUS_SESSION_BUS_ADDRESS

nsdo <yourns> google-chrome

[ausbin]

Yeah, I have some script named nsfirefox in my $PATH which looks like this:

#!/bin/bash

if [[ $# -ne 1 ]]; then
    printf 'usage: %s <nsname>\n' "$0" >&1
    exit 1
fi

nsname=$1
shift

DBUS_SESSION_BUS_ADDRESS= exec nsdo "$nsname" firefox --no-remote -P "$nsname" "$@"

Then I can say nsfirefox gatech if my netns is named gatech.

I need to add this to the README
