border_radius isn't recognized as a command even though i built the project from source about i3 HOT 4 CLOSED

Can you share the output of i3 -v?

from i3.

I don't know exactly how you are launching i3 (maybe from .xinitrc?), but if you are using the i3 in your path (ie. the i3 with the version you provided) then you aren't using this changeset. For example my i3 outputs i3 version 4.16.1-186-gf3fffbae (2020-03-01, branch "shape") © 2009 Michael Stapelberg and contributors. Notice branch "shape" as a key difference. So it could be one of a couple things:

• You mention installing i3-gaps, you might be using airblader/i3-gaps by mistake instead of this repo
• You built the wrong branch (shape should be default, but you can double check)
• You built i3, but didn't install it
• Old i3 is still installed and is being preferred for w/e reason

from i3.

The first option might be possible, however i don't think so. I'm gonna try installing the correct branch, thanks. And i followed all the instructions on the wiki so i'm pretty confident i did install i3. And finally it is possible the old i3 is still installed.. I removed it via apt remove command however...

Thanks for you help
