elementary OS 5.1.4 Hera Dual-Core Intel® Core™ i7-3537U CPU @ 2.00GHz
This is what happened:
1-After using Inkscape for a while, the image thumbnails disapeared from my system folders.
2-Following an advise, I cleared the cache in $HOME/.cache/thumbnails and $HOME/.thumbnails, using sudo rm -rf *, as per thread: https://ubuntuforums.org/showthread.php?t=2390636
3-Reeboted and the Files app shortcuts to Images, Documents, etc were gone.
4-Navigating to my Home folder and my user with the Files app, there were no thumbnails for any file, the folders all look empty. But hovering shows they have the normal size. On an external drive all is fine, and I got thumbnails back.
5-I restored the settings and reebooted, but the problem remains the same. And my keyboard now also is the wrong one, even though I chose the correct language and region PT, and reebooted yet again.
6-Also, I reinstalled Pantheon using the App Store, and reeboted and the issue remains. Finally, I launched Pantheon with sudo, and it-s exactely the same problem.
So please, I would really apreciate if someone coul help me: - Get back to normal navigation, in my File System - If possible, also choose the correct keyboard
Thanks in advance for your time.
