Thanks for chiming in. I’ve confirmed creating the file in the file browser under “Home > .config > MangoHud” places the file in /var/home/curious_dolphin/.config/MangoHud, so I’m still scratching my head as to why I’m unable to edit the document after the initial save. As a workaround, I’ve placed the config file in my top level home folder (aka /var/home/curious_dolphin) w/ a link to it from /var/home/curious_dolphin/.config/MangoHud where the app expects, and this seems to be working as desired.

Thanks for the tip to create a link to the file that is elsewhere. This works for me. I’m now able to configure MangoHud in a text file without using Goverlay.

Can you create any files in $HOME OR $HOME/.config/ ?

Yes - I can create (and later edit) files under /home/curious_dolphin, even under /home/curious_dolphin/.config, but for some reason once I’ve created a file under /home/curious_dolphin/.config/MangoHud, I cannot edit it even though the file and its parent directory appear to have the same permissions as the other files that I can edit.

In other words, after creating test.txt under /home/curious_dolphin/.config/MangoHud, I cannot edit it:

curious_dolphin@bazzite:~$ ls -la ./.config/MangoHud/
total 20
drwxr-xr-x. 1 curious_dolphin curious_dolphin   42 Feb 20 14:46 .
drwxr-xr-x. 1 curious_dolphin curious_dolphin  552 Feb 20 14:47 ..
-rw-r--r--. 1 curious_dolphin curious_dolphin 9671 Feb 20 12:22 MangoHud.conf
-rw-r--r--. 1 curious_dolphin curious_dolphin    5 Feb 20 14:46 test.txt

However, after creating test.txt under /home/curious_dolphin/.config, I can edit it:

curious_dolphin@bazzite:~$ ls -la ./.config
total 44
drwxr-xr-x. 1 curious_dolphin curious_dolphin  552 Feb 20 14:47 .
drwx------. 1 curious_dolphin curious_dolphin  460 Feb 20 14:41 ..
