Question about Thumbnails in File Manager (Gnome not Nautilus- I think)
If this is wrong place to post… Admin/mod please move accordingly and let me know where it lands. Thanks.
Have used Linux Fedora for hmmm. 10yrs now… rarely need to do anything but do updates when suggested. Have had huge issues (all same ones) from about update from 36 to 37 … it included an update to Nvidea… Things have been FUBARED ever since. On Linux 42 now?. Things tiny better… at least I can see menu text and file manager text now.
anyway… this may NOT be related. I’d like to have Thumbnails in the File Manager for Picture and Video folders. I have Thumbnails turned on… but get no thumbnails.
Any suggestions???
You may be lacking some packages. Do you use Fedora Workstation 42? If you do, then try
sudo dnf group install workstation-product-environment
Yes 42. Ifff have text in the terminal app … I’ll try that. For awhile had no text working in terminal, no text in any Fedora App menus, no file names either in File manager… now that text in file manager is back… maybe terminal works again will report back
reporting back… yeah… Terminal has text now. So ran what you suggested. bunch of stuff downloaded. had to say Y to a few things I did not fully understand… looks like it updated some Fonts too. will report back
What do you mean you didn’t had text? Your fonts were broken?
no text… blank … if I changed messed around with size of app on the screen… I could sometimes get a menu’s text to appear. messing around in File Manager with sort orders and how I moved the mouse would sometimes make the text appear in the File manager too. Those things seem to be now corrected. About to reboot system … assume that is next step after running the SUDO reccommeneded above.
Yup, you should reboot now.
thanks…
rebooted- Im sure somethings are different… but nothing obvious different… file manager acts the same. no thumbnails.
this is 42 workstation.
Well, that’s a weird one. For what file extensions does thumbnails don’t work for you?
none… have icon? for file folders and a few documents… that are not a thumbnails… hence why said Icon. … but nothing has thumbnail images… no matter then file extension. There seems to be an attempt if you look close (using “dark” screen setting) when I cursor over where thumbnail would be see faint lines of a box and a slightly different (lighter) hue of the black inside the lines… kind of like it is a placeholder for a thumbnail… but with nothing in it.
will read thru mucho thanx
Don’t thank me till you fix your problem 
using the suggested rpm in above link to verify if I had thumbnailers… it I think reports back that I do.
xxxxx@yyyy:~$ rpm -ql gdk-pixbuf2 | grep thumbnailer
/usr/bin/gdk-pixbuf-thumbnailer
/usr/share/thumbnailers
/usr/share/thumbnailers/gdk-pixbuf-thumbnailer.thumbnailer
Did you try clearing failed cache in ~/.cache/thumbnails/fail/?
Did you try running the thumbnailing command manually to verify that it is working? For example, Exec=/usr/bin/gdk-pixbuf-thumbnailer -s %s %u %o in a thumbnailer file would need the command gdk-pixbuf-thumbnailer -s 512 file:///home/myusername/file_example.jpg my_thumbnail.png.
have not tried that… dont even know if such file(s) exist… though by what you say… apparently they should LOL
but as a Linux idiot… I really dont understand how to go about what you’re suggesting.
