Hi everyone,
I am currently trying to set up i3 with polybar for my laptop in an Arch Linux fresh installation. I looked up and down everywhere here and the wiki but couldn't find a solution.
Basically I am following the Polybar Wiki Page to have the bar to autostart with i3; so I copied the launch script into my ~/.bin folder (the script basically kills previous bars, starts new one and creates a log file) and added the path with the exec_always command to the ~/.config/i3/conf file. The problem is that the bar doesn't start and looking at the i3 log file I'm getting a "Permission denied" problem.

exec_always --no-startup-id ~/.bin/polybar_launch.shI did try putting the full path in the command, but still I get the same permission error.
Additionally when I do this in the terminal:
sh ~/.bin/polybar_launch.shor add this in the i3 config file
exec_always --no-startup-id polybarit just works, with the latter actually keeping the bar at the next sessions.
That being said, I would like to use the script, both becuase I want i3/polybar to be coupled but most importantly because I want the log output file in case of errors.
What worries me is that I get the same permission error when I created a random .sh script and put it in the i3 config file; so I am currently thinking it could be an issue with my user permission in the system; but I am a bit lost now as to how find the problem.
Any suggestions would be much appreciated. Thanks!
EDIT: In case somebody encounters the same problem, it was indeed a permission error, and as I suspected it was wider than just i3.
Following the Security Wiki Page after installing Arch, I added the noexec mount option for my /home mountpoint, which apparently blocks not only binaries but also scripts. I found a nice explanation of why this happened and why on the other hand calling the bash interpreter in the terminal worked here.
Indeed changing the mount option now lets i3 load the script as intended.
