[SOLVED] Desktop files fails to open application,but exec commandworks

Hello all,

I recently tried some fenagling to get my media keys to work with foobar2000 (ran using wine) and had to edit my desktop file for the software to get it to work. As soon as I did so, I could no longer launch the software using the desktop file. Returning the file to its previous state no longer works either.

The output of desktop-file-validate my/desktop/file is blank.

The output of dex my/desktop/file is as follows:

07a0:fixme:msvcrt:_set_abort_behavior _WRITE_CALL_REPORTFAULT unhandled

Obviously, this hints that the issue is WINE related. I tried following the directions from this WINE forum post to downgrade Windows version to 7, but to no avail https://forum.winehq.org/viewtopic.php?t=35166.

My desktop file is as follows:

[Desktop Entry]
Type=Application
Name=foobar2000
Exec=beefweb_mpris
Icon=foobar2000

Following the wiki, I boiled the desktop file down to the bare minimum to get it to run and produced that. beefweb_mpris is a python wrapper script that enables media key integration via MPRIS support in foobar2000. Can be found here https://github.com/ther0n/beefweb_mpris. My foobar2000 exec file is as follows:

#!/bin/sh
cd ~/.local/share/foobar2000/
if [ "$1" != "" ]; then
filename=`echo z:$1 | sed 's/\\//\\\\/g'`
WINEPREFIX=~/.local/share/wineprefix/fb2k wine foobar2000.exe "$filename" &
else
WINEPREFIX=~/.local/share/wineprefix/fb2k wine foobar2000.exe &
fi

which is adapted from this guide on the hydrogen audio forums https://hydrogenaudio.org/index.php/topic,54933.0.html. I have also used this command as the exec command in my desktop file, but this returned the same error.

The commands beefweb_mpris as well as the one that I use to invoke foobar2000 work just fine when run from terminal. The desktop file is the only thing that does not work.

Re: [SOLVED] Desktop files fails to open application,but exec commandworks

add a "printenv > /tmp/foobar.env" to the script, run it either way and compare the environments.

Re: [SOLVED] Desktop files fails to open application,but exec commandworks

I couldn't add that specific line to the script, as it is a python rather than a shell script, but I ran the command in my terminal before and after invoking beefweb_mpris to see what happens. Here are the outputs:

Re: [SOLVED] Desktop files fails to open application,but exec commandworks

You're ultimately running this and it's what's executing wine, right?

#!/bin/sh
cd ~/.local/share/foobar2000/
if [ "$1" != "" ]; then
filename=`echo z:$1 | sed 's/\\//\\\\/g'`
WINEPREFIX=~/.local/share/wineprefix/fb2k wine foobar2000.exe "$filename" &
else
WINEPREFIX=~/.local/share/wineprefix/fb2k wine foobar2000.exe &
fi

It's because bugs are afraid of me wink

This of course renders any test pointless, the best thing I can suggest is to call back if the issue returns.

Re: [SOLVED] Desktop files fails to open application,but exec commandworks

Ah, I forgot to mention, but the desktop file is not executable from Nemo, and does not show up in my application menu (I am using Cinnamon Desktop Manager). I get the nondescript error message "There was an error launching this application". Using dex works fine. Idk at this point lol.

Hopefully me going about my day and coming back later fixes the issue, haha.

Re: [SOLVED] Desktop files fails to open application,but exec commandworks

Sorry, I am a bit confused by what you mean with "desktop service file". Is that the display manager service? Here is the output of 

systemctl --type=service --state=running

in case that helps. Or is it just the .desktop file? Please excuse my ignorance.

The .desktop file is what you're asking for. It is in the original post, but I'll paste its contents again here.

Re: [SOLVED] Desktop files fails to open application,but exec commandworks

Sorry, I thought that was just a boilded down version and not what you're currently using.
Do you get a printenv output from nemo?

Re: [SOLVED] Desktop files fails to open application,but exec commandworks

I do not get a printenv output. I put the print env at the very end of the script, though.

The output of what you sent is 

beefweb_mpris is /home/user/.local/bin/beefweb_mpris

Re: [SOLVED] Desktop files fails to open application,but exec commandworks

I suspect that's not part of the $PATH in the nemo context. Change the desktop service and try to execute it by its absolute path.

Re: [SOLVED] Desktop files fails to open application,but exec commandworks

It is definitely part of the $PATH as other desktop files stored there launch. I've also done what you said regarding the absolute path already and it did not change anything.

Re: [SOLVED] Desktop files fails to open application,but exec commandworks

It's not about where the .desktop file is stored.

Exec=/home/user/.local/bin/beefweb_mpris # but I suspect "user" is a placeholder?

Re: [SOLVED] Desktop files fails to open application,but exec commandworks

So I did what you suggested. I put beefweb_mpris into /usr/bin, and then I also tried explicitly specifying /home/user/.local/bin/beefweb_mpris (yes "user" is a placeholder). The desktop entry now shows up in the cinnamon application menu correctly. However, it does not launch when selected. The mouse cursor does turn into the wheel indicating something is happening. There is no output in journalctl, however.

Re: [SOLVED] Desktop files fails to open application,but exec commandworks

You didn't do both and are now trying to explicitly start the former path?
Does dex still work?
In doubt it depends on some other environment or even a stdout.
/usr/local/bin/beefweb_mpris.sh

#!/bin/sh
/usr/local/bin/beefweb_mpris > /tmp/beefweb_mpris.dbg 2>&1

Don't forget to "chmod +x /usr/local/bin/beefweb_mpris.sh" and then run that script instead of beefweb_mpris in the desktop service
/tmp/beefweb_mpris.dbg might indicate what it doesn't like.
If the file doesn't show up, beefweb_mpris.sh isn't executed at all

Re: [SOLVED] Desktop files fails to open application,but exec commandworks

Alright, so following your directions and doing some additional troubleshooting based on the error log printed out solved this issue.\

First, I got this:

Traceback (most recent call last):
  File "/usr/local/bin/beefweb_mpris", line 7, in <module>
    sys.exit(main())
             ~~~~^^
  File "/home/user/.local/share/venv/beefweb_mpris/lib/python3.13/site-packages/beefweb_mpris/main.py", line 39, in main
    foobar2000 = Popen([config['foobar2000-command']])
  File "/usr/lib/python3.13/subprocess.py", line 1039, in __init__
    self._execute_child(args, executable, preexec_fn, close_fds,
    ~~~~~~~~~~~~~~~~~~~^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
                        pass_fds, cwd, env,
                        ^^^^^^^^^^^^^^^^^^^
    ...<5 lines>...
                        gid, gids, uid, umask,
                        ^^^^^^^^^^^^^^^^^^^^^^
                        start_new_session, process_group)
                        ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/usr/lib/python3.13/subprocess.py", line 1991, in _execute_child
    raise child_exception_type(errno_num, err_msg, err_filename)
FileNotFoundError: [Errno 2] No such file or directory: 'fb2k'

The last line hinted to me that the script "fb2k" was not in $PATH. I then moved fb2k to /usr/local/bin, and FINALLY the desktop file executed the program.

Anyways, thanks a lot for helping, Seth.

\o/
Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.
