GUI won't launch Ubuntu 24.04 LTS Wayland

[Coder-DG]

Hi, I'm on Ubuntu 24.04.2 LTS on Wayland, I've followed the instructions for the universal package (updated the version in the text before running the commands) but nothing happens when I run ltr_gui.

At first from strace it seems like it was missing a lot of libraries so I added LD_LIBRARY_PATH to the command, but still it won't launch:

$ LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu:$LD_LIBRARY_PATH strace -o output_file.txt -f /opt/linuxtrack/bin/ltr_gui

QMetaObject::connectSlotsByName: No matching signal for on_Model1Pt_pressed()
QMetaObject::connectSlotsByName: No matching signal for on_ModelFace_pressed()
QMetaObject::connectSlotsByName: No matching signal for on_CloseButton_pressed()

The only missing libraries that I had were opencv ones which I thought might be optional. But it doesn't seem like it's doing anything.

It won't let me attach the strace output I captured for this, not sure where can I upload it

I'm not sure what's missing or how to proceed forward, can someone help me out here?

I am not sure if you have reviewed this thread but we have a few users showing the different ways we got this running #206 (comment)

@Coder-DG I am working to upload the code to work on modern OS and I have released an appimage that may help...but it needs testing and comments. This is a work in progress, I plan to continue to add features and improve compatibility .

I tried it out, and it actually works! For anyone else who reads this, I had to grab my TrackIR installation from my Windows machine to make the the bridge installation work. But MSFS2020 and DCS recognize it afterwards without issues (Steam and Lutris respectively).

Hi,
what if I dont have a Windows installation? My former Windows is in a Paragon Backup which I don't want to restore.
Can I just do a fast KVM install to setup a small Windows VM without registering and bring up the TrackIR Software?

[fwfa123]

No need to have a windows install. Just download the Trackir installer https://www.trackir.com/downloads/ and then in the Linuxtrack X-Ir GUI. Choose to install from that exe. Please see this page in the wiki...https://gitlab.com/fwfa123/linuxtrackx-ir/-/wikis/extractor NO WINDOWS required...wine will take care of it automatically. Best of luck...make sure you have Wine 9.0 or newer installed on your OS before running the extractor as the new installers from Trackir need the newer version of Wine to install fully

I should've clarified, the program was unable to extract w/e it needed from the TrackIR installation .exe because wine couldn't install it in my case, it kept failing. That forced me to grab the Windows installation which I have now saved as a .zip file on my Drive in future cases where I need to extract the files.

It definitely can fail depending on the Distro and what is installed, so your info was still very useful and helpful. But it should work without windows in most cases...but not all.

Thanks for the posting what worked for you. It helps
