Sessionx popup not working on Debian

[muradbozik]

The session popup window not showing up on Debian machine. Same configuration same versions (both tmux and plugin) works well on Ubuntu machine but not on Debian.

tmux version: tmux 3.3a fzf version: 0.53 (conda-forge) os version: Debian GNU/Linux 12.5 (bookworm) x86_64

Same problem on Fedora 40. There's a very brief flicker, but the popup won't appear/stay. Not sure if it's the same issue or just my personal fault, I'm just trying it for the first time.

tmux version: 3.4 fzf version: 0.44.1, fzf-tmux present

Had some time digging into that; there's another issue #22 which describes the same symptoms. https://github.com/omerxx/tmux-sessionx/issues/22#issuecomment-1902255317 solved the problem for me.

Hi people of this thread, does set -g @sessionx-window-mode 'on' help you at all? I'm not a debian user so hard for me to replicate the issue

I tried, but unfortunately it doesn't help.

I was also having this problem in NixOS with the Fish shell, and fixed it with the following modifications

Just to be clear, fzf-tmux is installed (it comes with tmux) and directly executing the script without modifications prints mkfifo: invalid mode: invalid digit found in string to the screen and does nothing. So I started commenting out code to see where the error was and saw it was the the RESULT= line. That's when I decided to replace fzf-tmux with fzf --tmux to see if it worked, and it did.

I'm having trouble with this on wsl. I have all the prequisites, fzf version 0.40.0, tmux version 3.4. Gone through all the discussion on this that I can find. tmux-fzf popup works for me though so that works for now but really interesting problem.

Thank you so much @acristoffers . I made the same changes and it worked.
