I would like to delete some images with nautilus.
I increased the size to 200%.
My monitor has a high resolution and the image are too small for me.
I would like to increase the size even more, but it seems to be impossible.
See screenshot.
Is there a particular reason why increasing beyond 200% is not possible?
I have Ubuntu 16.04 LTS and I've manually installed Ubuntu 18.04 LTS. Everything looks fine except video thumbnails. How to solve this?
I'm trying to stop Nautilus from creating thumbnails of PDF files. In another thread on 'Ubuntu forums' someone said to open gconf-editor and disable the PDF entry in the '/desktop/gnome/thumbnailers' directory. However the only entry in that DIR is disable all. Needless to say I don't want that.
How can I disable the thumbnails for a specific file type?
Nautilus's thumbnail cache in ~/.thumbnails has grown to several hundred megabytes.
Do I need to be concerned about unrestricted growth of this in the long term, or is its size automatically managed somehow?
For some unknown reason all thumbnails are lost in my Shotwell, instead all icons are grey. The images themselves are all okay and I can open them all in Shotwell.
There are only empty folders in .shotwell/thumbs/ so it looks like the thumbnails don't doesn't get generated at all.
I have also tried to re-install Shotwell (by purge it first) without any change.
How do I make Shotwell regenerate all the thumbnails?
