[SOLVED] Leafpad opens .png files by default

[Atip]

Alll my file managers (thunar, dolphin, spacefm, mc) open *.png files with leafpad which naturally does not make sense.

This is when I open the FMs as user. If I open as sudo the *.png files open with gthumb.

How can I change this that as user FMs will open with gthumb or viewnior?

[DidierSpaier]

There are tools to do that but I don't remember which right now. Anyway you could type this as regular user:

Code: Select all

sed -i "s/png=.*/png=viewnior/" ~/.local/share/applications/defaults.list

or directly edit the file ~/.local/share/applications to have in it:

Code: Select all

image/png=viewnior.desktop
image/x-png=viewnior.desktop

Of course replace viewnior with gthumb if you prefer.

This can also be done at the graphical interface with graphical dialog, e.g. with thunar, instead of editing files.

To do this, open the context menu of the PNG file to be opened in thunar and choose "Open with another application..." (possibly not literally). In the list that opens, select the application to be assigned. Then check the box "Use for files of this type" (possibly not literally). Then click on "Open" (possibly not literally). That's it.

This line:

Code: Select all

image/png=viewnior.desktop

is the default .local/share/applications/defaults.list. See: https://github.com/gapan/user-settings- ... aults.list

So this doesn't happen by default, it's something you did after installation.

[Atip]

Thanks all!

There is/was nothing wrong with ~/.local/share/applications/defaults.list.

After setting in thunar and dolphin to open *.png files with viewnior as default
application spacefm and mc followed suite automatically.

Yes, like upgrading with gslapt libpng after which I could not open dillo and gedit anymore since libpng*s needed for those programs went missing and possibly caused problem of Re: Subject as well.

What on earth are you talking about? If any of that happened, you're not using Salix.

[Atip]

Well, I am just reporting what happened.
And if I am not using Salix then the Northern Philippine Cobra on my avatar shall sink its poison fangs into me.

In order to use dillo again I copied the missing libs libpng14.* over from slackel and for gedit made a symlinc afterwards:

Code: Select all

ln /usr/lib/libpng14.so.14.12.0 /usr/lib/libpng12.so.0

Code: Select all

cat slackware-version 
Slackware 14.2

Code: Select all

cat ./slapt-getrc

You have changed so many things manually, outside of package management in your system, that it's not Salix, or any other distribution that anybody else is using anymore. There is no problem with libpng on Salix. It's only in your system, because of changes you have made.

In order to use dillo again I copied the missing libs libpng14.* over from slackel and for gedit made a symlinc afterwards:

Code: Select all

ln /usr/lib/libpng14.so.14.12.0 /usr/lib/libpng12.so.0

That's exactly what I mean.

Maybe its time to create a Don't Break Salix, similar to the Don't break Debian threads/wiki's, of course modified for Salix/Slackware.

We do have these:
https://docs.salixos.org/wiki/Can_I_use ... itories%3F
https://docs.salixos.org/wiki/Can_I_use ... h_Salix%3F

I can start work on this, if you guys think it could help.
