Re: [SOLVED]Thunar doesn't show xbm images as thumbnails

The gdk-pixbuf thumbnailer is supposed to provide xmb thumbnails:

$ xdg-mime query filetype circles.xbm 
image/x-xbitmap

$ fgrep -ri bitmap /usr/share/thumbnailers/ | awk -F':' '{print $1}'
/usr/share/thumbnailers/gdk-pixbuf-thumbnailer.thumbnailer

... but it doesn't seem to work. I'm not sure if the issue is with tumbler or with gdk-pixbuf.

Assuming tumbler version at least 0.2.0, you could create a desktop thumbnailer file and grant it highest priority - this will make it work. To do so:

1. Create the file /usr/share/thumbnailers/xbm.thumbnailer with the following content:

   [Thumbnailer Entry]
   Version=1.0
   Encoding=UTF-8
   Type=X-Thumbnailer
   Name=xbm Thumbnailer
   MimeType=image/x-xbitmap;
   Exec=/usr/bin/convert -thumbnail %s %i %o

   ...note that the imagemagick package needs to be installed for the convert command.

2. Copy /etc/xdg/tumbler/tumbler.rc to ~/.config/tumbler (create the directory if it doesn't exist)

3. Change the priority the "DesktopThumbnailer" entry to 3 (so it looks like):

   # thumbnailers provided by .thumbnailer desktop files
   [DesktopThumbnailer]
   Disabled=false
   Priority=3
   Locations=
   Excludes=
   MaxFileSize=2147483648

4. You need to restart tumbler and thunar - probably easiest to log out and back in again.

To properly fix this, you might want to start with a tumbler bug report but it might be an issue with gdk-pixbuf.

Thanks. I did all that, but it didn't work.
This is Arch Linux and the system is Openbox. But, on XFCE too xbm files couldn't be seen, bug reports had been placed.

I did all my testing on Arch linux and it does work. As a sanity check, can you post back the following:

xdg-mime query filetype FILE.xbm

...where "FILE.xbm" is the name of the xbm file.

cat /usr/share/thumbnailers/xbm.thumbnailer

cat ~/.config/tumbler/tumbler.rc

which convert

ps -ef | grep tumblerd

Also maybe reboot just to be sure (some Xfce processes remaining running if you just log out.
