"Error: Failed to open controlling terminal with error: input/output error" on kitty terminal

[sr-prog]

This error appears when I launch lf while using ctpv, I'm currently using kitty 0.28.1 and I think this error comes on versions that are higher than kitty 0.26.5 but I'm not 100% sure about it. Also I'm using icat for previews not ueberzug. Also image preview works completely fine but this error message coming up every time I launch lf is annoying and I'm not sure what's causing it to appear. Also I have tested and this error is there when I load kitty without any custom config.

I'm seeing a similar error in Kitty when using ctpv in a fzf preview command (with a wrapper that starts and stops the daemon in the background and sets the sizes)

[sr-prog]

So I figured out what was wrong, it's because of this command:

I saw the readme and it looks like maybe this command is deprecated or something in favor of a ctpvquit command so I just replaced this in my lfrc

set previewer ctpv
set cleaner ctpvclear
&ctpv -s $id
cmd on-quit $ctpv -e $id

with this:

set previewer ctpv
set cleaner ctpvclear
&ctpv -s $id
&ctpvquit $id

TLDR; replace ctpv -e with ctpvquit I guess

If this fix doesn't work for anyone else who sees this I can re-open the issue on your request.

I'm still experiencing this error when used in fzf previews, but that may as well be a problem with fzf itself

ctpvquit is a wrapper around ctpv -e which just checks an lf process is running and if it's not, it kills the background process. I added it because cmd on-quit is a pretty new addition to lf and a lot of people don't have it. Maybe you also have an old version of lf, which caused the issue?

Does it happen in terminals other than kitty? How did you integrate ctpv into fzf?

[tionis]

The issue only happens in kitty. I just used the fzfp script in the stpv repo and replaced the calls to stpv with appropiate calls to ctpv
