Start ``dmenu_run`` from the command line, and see if there is some error. One possibility is that the cache file that ``dmenu_run`` uses internally, somehow has not updated itself to include this application. If so, deleting the cache file will cause it to be regenerated. Look at ``less $(which dmenu_run)`` to find the location of this cache file. If not, check if the binary is in $PATH as dmenu_run sees it. Good luck!

In my version that would be `| ${SHELL:-/bin/sh} >tmp/dmenu_log 2>&1 &`. Maybe write a line in dmenu_run to the effect of `env >> tmp/dmenu_env`, as I suspect the error to be in the environment not completely set.

Deleting the cahce doesn't help anything. But if i run the dmenu_run from terminal and then tries to open matlab from the dmenu_run it works like a charm.

For a solution: Add the directory where the executable of matlab lives to your PATH.

In /usr/bin make a script named matlab that contains this: !#/bin/bash /usr/local/MATLAB/R2014a/bin/matlab -desktop` make it executables: `chmod a+x matlab` not you should be able to run matlab from dmenuSun, 04 May 2014 13:56:11 +0000https://faq.i3wm.org/question/2564/cant-open-matlab-from-dmenu/?answer=3765#post-id-3765Answer by adder for Hi I'm pretty new to i3, but danm i have to say i love it!

Thanks in advance! https://faq.i3wm.org/question/2564/cant-open-matlab-from-dmenu/?answer=3143#post-id-3143I have issues with matlab and dmenu too. I could not launch matlab from dmenu. I partially solved the issue by putting an one-line shell script in my PATH with the line: /path/to/matlab -desktop. Now, the strange thing: If I have a window open (like an xterm) in the current workspace, then launching the above script with dmenu starts up matlab fine (albeit, in half the screen). Then I can move the matlab to a new workspace on its own. But, if I launch the above script on an empty workspace, matlab doesn't start properly and I only get a grey window.Wed, 01 Jan 2014 17:40:59 +0000https://faq.i3wm.org/question/2564/cant-open-matlab-from-dmenu/?answer=3143#post-id-3143
