Stopping Tumblerd in XFCE

Tumbler is a D-Bus service for applications to request thumbnails for various URI schemes and MIME types. It is an implementation of the thumbnail management D-Bus specification described here.

• Issues with Tumblerd: 
• Using more memory and CPU
• Preventing removable storage devices from unmounting(then, ejecting)
• External HDD
• USB Pendrive
• CD/DVD 
• Usually, locking of external devices occur with Video files

$ lsof /run/media/mitesh/PHONE\ CARD
COMMAND   PID   USER   FD   TYPE DEVICE  SIZE/OFF NODE NAME
tumblerd 1268 mitesh    9r   REG   8,17  34902492 1625 /run/media/mitesh/PHONE CARD/video/abc.mp4
tumblerd 1268 mitesh   10r   REG   8,17  69869584 1624 /run/media/mitesh/PHONE CARD/video/def.mp4
tumblerd 1268 mitesh   11r   REG   8,17  35883924 1627 /run/media/mitesh/PHONE CARD/video/ghi.avi
tumblerd 1268 mitesh   14r   REG   8,17 293435929 1629 /run/media/mitesh/PHONE CARD/video/jkl/mno.flv
tumblerd 1268 mitesh   15r   REG   8,17 240015268 1630 /run/media/mitesh/PHONE CARD/video/jkl/pqr.flv

So, in order to get rid of this blocking process tumblerd, we can kill the tumblerd commands given by lsof, as:

$ lsof /run/media/mitesh/PHONE\ CARD/ | awk '{print $2}' | grep -v PID | xargs -L 1 kill -TERM

PS: Please replace /run/media/mitesh/PHONE\ CARD/ with the mount point of the removable device, which is not allowed to be umounted.


If we want to remove this tumblerd, we can give following command:

• Fedora
• $ sudo yum remove tumbler
• Debian/Ubuntu
•  $ sudo apt-get remove tumbler
