Just as the subject line says, I'm not getting any thumbnails. Not for jpg, not for png, and not for videos either. It's the regular file manager that comes with this installation ("Simple file manager for Gnome"). I've gone to /Preferences/Search & Preview and made sure it's set to always show thumbnails but it doesn't. Any suggestions?

  • Silly question, but have you closed Files and reopened it since changing the preview setting?

As I haven't been able to fix the issue, I installed Nemo as an alternative file manager and lo and behold, thumbnails are back on the menu! Nemo is a more elaborate and hence to me more useful file manager anyway. Note that in the software center it appears only as "Files" which is... err... unhelpful. In the description, the word "Nemo" is mentioned though so it's not that hard to find.


Install FFMPEG Thumbnailer

sudo apt install ffmpegthumbnailer

Then close and reopen file manager. Thumbnails for most video files should generate now.

Otherwise, delete ~/.cache/thumbnails and restart your computer
