Unable to run backintime via x11

[philm001]

Hello everyone, I am unable to run backintime through x-11. This is really unfortunate because it would give us headless users a nice way to work with this program. I am adding the output of the command here. I should note, that I am pretty sure I have the authorization correct for what I am doing

Hello Phillip,

Thank you for taking the time to report the bug and providing the
details. I appreciate your feedback.

Can you describe please in more details what "through x-11" means. I see "MoTTY" in your output. Might this be some kind of remote desktop setup like VNC or XRDP?

In this case I would suggest to ask the community of your client first and provide the same details. They might have an idea what could be the cause.

btw: I don't have problems running BIT via XRDP (using "Windows Remote Desktop" as client) on Debian 11 and 12.

Best regards,
Christian

Are you using MobaXterm for X11-forwarding?

I don't know if X11-forwarding with BiT GUI was ever tested or reported as working.

This is my xauth values:

Is "my" a normal user or root?

[Martii]

I don't know if X11-forwarding with BiT GUI was ever tested ...

Not sure if this is what is being looked for but this seems to load and pull up my existing snapshots:

$ ssh -CX machine.localdomain /usr/bin/backintime-qt

That target machine is "headless" when it comes to hardware i.e. no monitor (except when selected with a KVM) but still has the same distro Windows Manager installed. I usually use VNC though as it is "detachable" i.e. continues to run when host system is rebooted or otherwise busy. The BiT GUI (Qt) in general looks a bit different on fonts/button images... might be applying the default KDE theme instead of my distros.

confirm, has worked for me for many years openSUSE Tumbleweed

Hello guys thank you for feedback. I was able to get things working on the CLI (I would suggest some more up to date documentation on the CLI part). However, I think that having a good way to use X11 is beneficial.

@aryoda

Yes, I am using that. I can run the X11 apps like the clock and the eyes without issue. I only have a problem with BiT. I haven't tried using vnc or XRDP. I will give those a shot later and see if it might be an issue with Mobaxterm. I am pretty sure those are under a normal user and I actually have both. But will need to double check that

Thanks for your feedback.

Please be more specific here. Otherwise we are not able to improve it. Which part of the docu you are refer to? The manpage, the user manual, something else? What could be improved or what is hard to understand?
