Not sure how to troubleshoot this. Any idea?

No.
https://bbs.archlinux.org/viewtopic.php?id=57855

I'd "scrot -F - | xsel -i", you probably want to https://man.archlinux.org/man/extra/xfc … ter.1.en#c and for everything else, you'll have to elaborate a bit on the problem.
Like, eg., describing it and also the environment (eg. if you're trying that in a wayland session, it will very most likely not work)

pm3840 · 2024-03-30 18:21:22

Well, it's all GUI. I've checked journalctl but nothing is there.
clipman is running and its tray icon is on taskbar. No problem there too.

Let me try though.
I open a terminal and run this "xfce4-screenshooter -f -c". There's no error. Same goes for "xfce4-screenshooter -r -c"
What else can be attached here?

$ xfce4-screenshooter -f -c
$ echo $?
0

The alt for me is to open captured in chromium and then go to chromium and do "copy image"

xfce4-screenshooter -f -c
xsel -o > /tmp/test.file
file /tmp/test.file
xsel -o -b > /tmp/test.file
file /tmp/test.file

pm3840 · 2024-03-30 20:05:16

$ xfce4-screenshooter -f -c
$ xsel -o > /tmp/test.file
$ file /tmp/test.file
/tmp/test.file: ASCII text
$ xsel -o -b > /tmp/test.file
$ file /tmp/test.file
/tmp/test.file: ASCII text, , with no line terminators
$

Here it is. Thank you!

So those are text files, it seems screeshooter doesn't put anything onto the clipboard.
Do you use some sort of clipboard manager?

There apparently used to be https://bugzilla.xfce.org/show_bug.cgi?id=15244 - can you get screenshots of small(er) screen fractions into the clipboard?

pm3840 · 2024-03-31 00:05:54

Yes I use xfce4 clipman. According to doc https://docs.xfce.org/apps/xfce4-screenshooter/usage it's required for this feature to work

Copy to the clipboard option allows you to paste the screenshot in another application, such as a word processor. This option is only available when a clipboard manager is running."

Chromium "copy image" works just fine, even big size image.

I see that quite a few bug reports were determined to be invalid. And the new bug tracker at https://gitlab.xfce.org/apps/xfce4-screenshooter doesn't have much.
I don't think there's a second clipboard manager running if that matters.

When you copy the image to the clipboard, does clicking on the clipboard icon in the panel display the image in the history? If not, can you confirm your version of xfce4-screenshooter?

Edit: the clipboard contents should be saved to ~/.cache/xfce4/clipman - check if the image file shows up there.

pm3840 · 2024-03-31 01:27:26

No. History is not touched. Version is the latest available:

$ pacman -Q|grep screensh
xfce4-screenshooter 1.10.5-1

xfce4-screenshooter doesn't affect ~/.cache/xfce4/clipman/image0.png. Chromium "copy image" does.

toz · 2024-03-31 02:46:15

Perhaps you could do a quick debug build of the package to see exactly what's happening (no need to actually install this build)?
-snip-
This will generate debug output which you can post back.

You may need to install some extra packages like base-devel, intltool and xfce4-dev-tools, but you can remove them later.

Edit: probably not a good idea to just drop random code here. You can find the debug parameters here. You can create a temporary build, without actually installing, by grabbing the source from the official upstream source repository (or building directly from git) with "--enable-debug=full". This will generate debug output when you manually run xfce4-screenshooter from the build's "src" directory.

screenshooter depends on xclip, which doesn't ship a library…

scrot -F - | xclip -i
xclip -o > /tmp/test.png
file /tmp/test.png

pm3840 · 2024-03-31 13:03:11

Excuse my C lang skill.

I find the logic here weird like the actions are offered as radio buttons not check boxes so why does the code do more than specified? screenshot is saved to "tmp" directory anyway when "copy to clipboard"
https://gitlab.xfce.org/apps/xfce4-scre … _type=tags

if (sd->action & CLIPBOARD)
    screenshooter_copy_to_clipboard (sd->screenshot);

if (sd->action & SAVE)
    {
      ...
   }
else {
      GFile *temp_dir = g_file_new_for_path (g_get_tmp_dir ());
      gchar *temp_dir_uri = g_file_get_uri (temp_dir);
      gchar *filename = screenshooter_get_filename_for_uri (temp_dir_uri,
                                                            sd->title,
                                                            sd->last_extension,
                                                            sd->timestamp);
      save_location = screenshooter_save_screenshot (sd->screenshot,
                                                     temp_dir_uri,
                                                     filename,
                                                     sd->last_extension,
                                                     FALSE,
                                                     FALSE);
}

This part is straight forward. According to GTK doc GTK takes care of everything pretty much.
https://docs.gtk.org/gtk3/type_func.Cli … splay.html

  clipboard =

  gtk_clipboard_set_image (clipboard, screenshot);
}

seth · 2024-03-31 13:58:41

actions are offered as radio buttons not check boxes so why does the code

The code there (has horrible newline/indention patterns and) checks whether some sd-action flag is set, the settings could translate to that exclusively ie. "sd->action & (CLIPBOARD|SAVE) == CLIPBOARD|SAVE" isn't an expected condition.

Did you test whether you can scrot into xclip?
The problem might be gtk_clipboard_set_image

pm3840 · 2024-03-31 14:48:08

Forgot to attach the debug build log. gtk_clipboard_set_image() might fail but its type is void doesn't return anything.

scrot works.
screenshooter also works just the clipboard part fails.

xclip doesn't affect clipboard either. only X selections.

Please use [code][/code] tags, not "quote" tags. Edit your post in this regard.

But I don't understand why screenshooter drags in xclip if it uses the gtk function.

Is this a regression, ie. has this worked in the past an only fails now?

Edit: "xclip -i -selection clipboard"

This works for me on my systems, so its not a regression. There is something askew here though as you suggest, maybe with gtk_clipboard_set_image?

Edit: @OP, can you post back:

xfconf-query -c xfce4-panel -lv | grep clipman

Or maybe something with clipman settings?

You're also running clipman on xfce?

pm3840 · 2024-03-31 15:14:06

clipman still doesn't pick up

$ scrot -F - | xclip -i -selection clipboard
$ xclip -o -selection clipboard > /tmp/test.png
$ file /tmp/test.png
/tmp/test.png: PNG image data, 3840 x 1200, 8-bit/color RGB, non-interlaced

pm3840 · 2024-03-31 15:18:11

I'm a new user to xfce wouldn't know if this worked before.

Funny xclip doesn't always complain about bad options:

$ scrot -F - | xclip -i --selection clipboard
xclip: --selection: No such file or directory
$ xclip -o --selection clipboard > /tmp/test.png
$ file /tmp/test.png
/tmp/test.png: ASCII text, with no line terminators
$ xclip -o -selection clipboard > /tmp/test.png
$ file /tmp/test.png
/tmp/test.png: PNG image data, 3840 x 1200, 8-bit/color RGB, non-interlaced
$

seth · 2024-03-31 15:22:07

"--selection" is simply wrong, it doens't use the gnu doubledash syntax.
If you quit/kill clipman, does screenshooter work as expected?

pm3840 · 2024-03-31 15:27:04

Yeah but it doesn't complain when -o is used

Same. Clipboard is not updated.

$ ps ax | grep clip
 354079 pts/8    S+     0:00 grep --color=auto clip
$ xfce4-screenshooter -f -c
$

lambdarch · 2024-03-31 15:52:13

@toz You probably have "Remember last copied image" enabled in clipman history?
With this option unchecked I can reproduce the issue.
I think it's this one: https://gitlab.xfce.org/xfce/libxfce4ui/-/issues/105

pm3840 · 2024-03-31 16:15:01

Yes I have this enabled "Remember last copied image" and at least Chromium "Copy image" works.
If this is not enabled, Chromium "Copy image" also fails.

lambdarch · 2024-03-31 16:30:21

It always works for me with this option enabled, not sure what happens then.
