[Error] Distrobox hostname issues freezing the system

[scuba3198]

Describe the bug
For some reasons graphical applications seems to freeze the system in general in distrobox containers but afterwards it recovers. The issue seems to be caused by the hostname. When the hostname is set for example as “teufort” graphical apps freeze after awhile or when interacting with the menus. When the hostname is the LAN address (192.168.1.10) it doesn’t freeze at all.

To Reproduce
Use KDE Plasma. I use Kubuntu LTS.

Expected behavior
App should be smooth. When I set my hostname to local LAN, the containerized app runs smooth with zero hiccups.

Desktop (please complete the following information):

• Are you using podman, docker or lilipod? podman
• Which version or podman, docker or lilipod? podman version 3.4.4
• Which version of distrobox? 1.5.0.2
• Which host distribution? Kubuntu 22.04
• How did you install distrobox? PPA

Additional context
here is a recording demonstrating the problem:

This issue for toolbox might be related.

I just started using Distrobox and cannot figure what exactly is the solution.

Thanks @Mattheish for the report

This seems to be unique to KDE, as (from my tests) stuff like i3/sway, XFCE and GNOME do not suffer from this

Are you able to provide some logs from the KDE session so that I can try to find a solution?
Thanks!

@89luca89 What fixed it for me was to add my_containername.my_hostname to the /etc/hosts file of the host. But It's more of a workaround since I would need to do this for each container/distrobox that I create.

I experienced this too (also kde plasma), but since d26a926 you can use --hostname argument to set the hostname to your host hostname when creating a container, also referenced in useful tips

[89luca89]

For this I've now reopened the discussion #62

The idea is to default to host's username for the container, and use $CONTAINER_ID for default prompt

Let's discuss in that issue for the impact of this change on workflows and/or breakages that this could lead

Please reopen. This is a severe issue that makes it impossible to use distrobox practically. It should be the top issue.
