In general, when adding a propagated input, could you add a comment in
the code itself explaining why it’s this way?
In this particular case, is the ‘lxqt-config-monitor’ command part of
libkscreen? Could we avoid propagation somehow?
Thanks,
Ludo’.

Hi,
The problem is crashing the `lxqt-config-monitor` when I want to run it(`segmentation fault`). I installed the `libkscreen` and the problem was resolved. So I change the `lxqt-config` package definition and remove the `libkscreen` from `inputs` to `propagated-inputs`, install it and everything was ok.
Regards,
Hamzeh.

Do you have a simple ‘operating-system’ configuration and instructions
we could follow to reproduce the initial problem?
Thanks in advance,

Hi,
maybe I could describe better about this patch file.
`libkscreen` is used by `lxqt-config-monitor` to modify
the desktop resolution in LXQt desktop.
the problem is that, during execution of `lxqt-config-monitor`
application crashes with "segmentation fault".
we had a review over `lxqt-config-monitor` source code,
but didn't find any unusual usage of `ksceen` library. just
a normal link during build process and binaries were made
successfully.
this issue might because of crash inside `libkscreen`, but we
didn't review that yet.
so as a quick workaround we find that adding the `libkscreen`
as a propagated input could fix this issue.

Thanks for explaining, I understand better now.
I think that it’s not satisfying to apply a workaround that we don’t
understand. That is, intuitively, I see now reason why propagating
libkscreen would “fix” a segfault.
Could you either (1) provide an ‘operating-system’ config and
instructions to reproduce the problem, or (2) grab a backtrace of the
segfaulted program with GDB?
Let us know if you need guidance.
Thanks,
Ludo’.

Hi Ludo,
Sure, here is a minimal operating system configuration that we used for a
minimal LXQt desktop on Guix:

the issue occurs when I try to execute `lxqt-config-monitor`.
here is also the GDB backtrace log that I received during application crash:

I added a window manager to the global profile so that I could actually
log in, but then I don’t even know how to get a terminal… I think I’m
not well positioned to further debug this. Did you discuss it with
upstream?

I did some investigating myself and I think there's a regression in
qtbase somewhere.

Hi,
Finally we can fix this issue with wrapping the `lxqt-config` and `lxqt-config-monitor` and add the `libkscreen` path to `PATH` environment path. I updated based on this patch and it fixed.
