If anyone saw my previous topic, this started happening after I resolved all of those issues. qBittorrent launches OK from the command line but the application launcher in the menu no longer works, it does nothing.

I'm not sure where to begin troubleshooting this. All I could do was try to reinstall it, but no joy there.

Ideas?

How do you launch it from the command line... like ./this from the program directory, or is it in your binary path? (/usr/bin, /usr/local/bin). If you have installed it to a user directory you would have to add it to your PATH environment variable to be able to launch it from an application launcher.

There are various ways to do it ~/.bash_profile or ~/.bashrc ... I just add things like that to /etc/profile so it's global but that wouldn't be appropriate to add something in your home directory there. For example, I put the results of my Chromium builds in /opt/chromium and I want it to launch from panel launchers and friends. So I need /opt/chromium added to my path:

# Set the default system $PATH:
PATH="/usr/local/bin:/usr/bin:/bin:/usr/games:/opt/chromium"

If you use another method, make sure you don't override that PATH variable... include it in any PATH variables.

export PATH=$PATH:/additional/directory/here

If not that, view properties of your application launcher and see if anything is amiss (working directory for example)

I'm sorry but I am not aware of your previous thread and I don't know what you already know.

Yes qbittorrent is in the path. This started after I installed gdm and edited /etc/inittab to runlevel 4.

In that case, it might not be getting the correct PATH variable from the environment. (or overriding it)

See gdm.conf (/etc/gdm.conf or /etc/gdm/gdm.conf or perhaps /usr/local/etc if you didn't set --sysconfdir when compiling it)

DefaultPath=

You might also try creating a ~/.bashrc file and adding the path there.

It's got to be something to do with the environment for it to work in a terminal (that would get the variables from shell configuration files) vs. application launchers.

I don't seem to have a gdm.conf, but there is a custom.conf in /etc/gdm. qbittorrent is in /usr/bin and it seems to be the only program affected.

An error message might have been logged to your .xsession-errors file.

It says it couldn't find libtorrent-rasterbar shared library.

The question now becomes: how did you install qbittorrent and its dependency libtorrent-rasterbar?
Did you compile from sources, did you use the SlackBuilds.org scripts or did you use my packages?

The OP stated that the app launched correctly from the command line.

I was using the slackbuilds scripts originally. I tried removing qbittorrent and installing your package, which didn't fix it. I didn't even consider installing your libtorrent-rasterbar package until now, and that did fix it, so thank you sir!

I just wish I knew what caused it to break suddenly.

It makes more sense now, knowing that this program runs without X depending on invocation.
