As you can see all libs/progs that are required are installed.
If Thunar is run a regular user thumbnails display.
Any ideas

Stop running GUI programms as root.


Perhaps at the XFCE forum

If you run it inside your user account - but as root instead - I’m not surprized.

Running it that way will probably introduce even more problems - messed up file and directory permissions are likely.

as others said: don’t do that
a rhetorical question: Why did you feel the need to do that?

If you log in as root via display manager (which you should not do - probably also cannot do without some fiddling around …)
it would work as expected.

Did you know that thunar is run as a daemon process? … in the user account’s context?

tumbler, by itself, will likely work as expected - just not in that … weird configuration
