[SOLVED] thunar is unable to display the thumbnail of the x11 cursor

os : arch linux
xfce 4.20
The optional dependency packages have all been installed, but the cursor image of x11 still does not display

I don't know if thunar doesn't support displaying x11 cursor images

I'm not sure what type of image they are but it's likely because of a missing library. Maybe bitmap?

Re: [SOLVED] thunar is unable to display the thumbnail of the x11 cursor

You can create  custom desktop thumbnailer for them.

1. Install the packages "imagemagick" and "xcur2png"

2. Create the file /usr/share/thumbnailers/xcusrsor.thumbnailer with the following content:

   [Thumbnailer Entry]
   Version=1.0
   Encoding=UTF-8
   Type=X-Thumbnailer
   Name=Xcursor Thumbnailer
   MimeType=image/x-xcursor;
   Exec=/usr/local/bin/xcursorthumbs %i %o %s

3. Create the file /usr/local/bin/xcursorthumbs with the following content:

   #!/usr/bin/env bash
   
   if TEMP=$(mktemp --directory --tmpdir tumbler-xcur-XXXXXX); then
   	xcur2png -d $TEMP -q -c - $1 > /dev/null 2>&1	
   	convert -thumbnail "$3" "$TEMP/*_000.png" "$2" &>/dev/null
   	rm -rf $TEMP
   fi

   ...and make the file executable.

4. Either log out and back in again, or kill both the thunar and tumblerd process to force a re-read of the new configurations.

Re: [SOLVED] thunar is unable to display the thumbnail of the x11 cursor

@Toz Hello, the problem hasn't been solved yet，He still doesn't work
1. It seems that archlinux does not consider Tumbler as a dependency of xfce4, which means that my system does not have Tumbler installed，Then I installed Tumbler
2. It seems that it has less dependence：

May 02 21:50:38 thinkpad tumblerd[1395]: Failed to load plugin "tumbler-odf-thumbnailer.so": libxml2.so.16: cannot open shared object file: No such file or director     y
   1 May 02 21:50:39 thinkpad tumblerd[1395]: Failed to load plugin "tumbler-gepub-thumbnailer.so": libgepub-0.7.so.0: cannot open shared object file: No such file or di     rectory

3 .

resolving dependencies...
looking for conflicting packages...
error: failed to prepare transaction (could not satisfy dependencies)
:: installing libxml2 (2.14.2-2) breaks dependency 'libxml2.so=2-64' required by ardour

:: installing libxml2 (2.14.2-2) breaks dependency 'libxml2.so=2-64' required by sane

It seems that I have to update the system…

I think it should be caused by the failed startup of tumbler？

2. Those are optional dependencies. See: https://archlinux.org/packages/extra/x86_64/tumbler/.

3. Where is this error message from?
