[SOLVED] xfce4 screenshot cannot be saved to clipboard

seth · 2024-03-31 17:23:56

w/ -o "--selection" gets silently ignored., just to be clear:
1) scrot into xclip can be pasted from xclip but doesn't show up in clipman?
2) screenshooter -c neither shows up in clipman nor can be pasted by xclip?
3) does "scrot -a 0,0,128,128 …" behave differently (it'll take the upper left 128² px)?

1. correct. as if clipboard is not touched.
2. same. no picture data at all. clipboard is not touched.

$ xfce4-screenshooter -f -c
$ xclip -o > /tmp/test.png
$ xclip -o -selection clipboard > /tmp/test1.png
$ file /tmp/test*
/tmp/test1.png: ASCII text, with no line terminators
/tmp/test.png:  ASCII text, with no line terminators
$

3. small size doesn't help either.

$ scrot -a 0,0,128,128 - | xclip -i -selection clipboard
$ xclip -o -selection clipboard > /tmp/c.png
$ xclip -o > /tmp/c1.png
$ file /tmp/c*.png
/tmp/c1.png: ASCII text, with no line terminators
/tmp/c.png:  PNG image data, 128 x 128, 8-bit/color RGB, non-interlaced

This acts exactly as you'd expect it to?

I'd expect that clipman picks up any change to clipboard and it's not happening for xclip or screenshooter. So far Chromium/FireFox works.

FWIW clipman doesn't see that for me either.

lambdarch · 2024-03-31 19:33:18

Ah, with '-target image/png' as suggested in https://unix.stackexchange.com/question … k-properly it works

pm3840 · 2024-03-31 19:44:20

Oh man this is it....

scrot -a 0,0,256,128 --format jpg - | xclip -i -se c -t image/jpeg

this is also picked up by clipman.

Safe to say screenshooter does not fit clipman then?

pm3840 · 2024-03-31 19:46:23

Err.....

Only my screenshooter doesn't work. I get it.

No dated AUR surprises there - have you tried the behavior w/ a fresh user account (to rule out some weird local config issue, broken syntax in a config file that doesn't flare up in teh GUI or whatever)?

screenshooter works in a new user's xfce4 session.
So 'sudo diff -rw ~user1/.config/xfce4 ~user2/.config/xfce4' is done and the only outstanding difference in xfce4-panel.xml is

    <property name="plugin-17" type="string" value="xfce4-timer-plugin"/>
    <property name="clipman" type="empty">
      <property name="tweaks" type="empty">
        <property name="inhibit" type="bool" value="false"/>
      </property>
      <property name="settings" type="empty">
        <property name="max-images-in-history" type="uint" value="1"/>
      </property>
    </property>

I then proceed to make a backup of xfce4-panel.xml, remove the difference from xfce4-panel.xml, logout and login.
Upon login there's a prompt saying clipman is already running. Then I go to "Settings / Session and Startup / Application Autostart" and uncheck "Clipman". Logout and login.
No more warning this time and testing is successful.
Trying with a different local user with fresh config is a great idea.

I have no idea when the max history disappeared and reappears. It's this the same as "Remember last copied image" and it has always been checked as it's the default. Also, Chromium/Firefox always worked.

$ xfconf-query -c xfce4-panel -lv | grep clipman
/plugins/clipman/settings/max-images-in-history     1
/plugins/clipman/tweaks/inhibit                     false

Thank you all very much.

Oh yes, they're actually enabled by default, sorry. I was fooled by the fact that if you reset them in xfconf with the clipman settings dialog open, the checkboxes are unchecked (because of the binding with GObject, which is confusing in this case).

Anyway, I don't really understand why it now works for you when it didn't before. Also, there's a bug in this story, as I said in #23, either on our side (Xfce) or on GTK's side.

lambdarch · 2024-04-01 21:53:49

I think I've managed to cobble together a solution for 4.20, my tests are conclusive. Until then, you might prefer to use clipman's underlying clipboard manager instead of xfsettingsd's (they'll be identical in 4.20, now shared in libxfce4ui). The easiest way to do this may be to export XFSETTINGSD_NO_CLIPBOARD=1 in ~/.profile.

I'm a new user to xfce. As I got used to the environment I started using more apps.

At the beginning I added the clipman widget to panel, and clipman worked as chrome/ff copy/paste texts are logged(I didn't pay attention to picture).

Some time later I started to use screenshooter and noticed that cilpman can be automatically started in "settings/session and startup". This is probably when I noticed that the picture copy/paste didn't work for screenshooter but chrome/ff still worked.

Are you implying that these two(widget/xfsettings) are not the same and perhaps I was running two instances of clipman? I thought I did check running processes and only saw one clipman running.

Yes.

No.

It's true that all this is quite confusing, so I'll try to clarify a little.

First of all, there are two different things:
* the X11 clipboard manager, which runs as a daemon and does not appear to the user;
* the user interface with menu, history, etc.

Only one process can act as X11 clipboard manager. On a normal Xfce session, it's xfsettingsd that takes care of this, but if it's not running when clipman starts, then clipman takes care of that too. And until recently, xfsettingsd and clipman had different X11 clipboard managers, each with their own bugs... They now share the same code hosted in libxfce4ui (in dev version, so it won't be the case for the end user until Xfce 4.20).

As for clipman, it can be launched as a panel plugin or as a systray icon, the two possibilities being mutually exclusive. Autostarting with the Xfce session starts it as a systray icon, so you need to disable it if you're using clipman as a panel plugin (which you did).
