Same issue for me since several Ubuntu versions on 2 different computers (24.10 and 24.04)
And same : if I empty the /home/jpaul/.cache/thumbnails/fail/gnome- thumbnail-factory/ AND open a Nautilus window of the desktop, the right icons is created immediately. After #9, the problem seems to be when we save the file on the Desktop folder, any pdf, Libreoffice, jpg… files. To get it : go to Internet, find a .jpg file and save it : * 1 : in the Desktop folder : the thumbnail doesn't appear either in Nautilus or on the Desktop view but a black thumbnail with only one pixel appears in /fail/gnome-thumbnail-factory/ (attached file) * 2 : in another folder : the thumbnail is well created ** Attachment added: "bad thumbnail" https://bugs.launchpad.net/ubuntu/+source/gnome-desktop3/+bug/2086516/+attachment/5850585/+files/986c5369f1f115bc94104d4229377607.png -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-desktop3 in Ubuntu. https://bugs.launchpad.net/bugs/2086516 Title: gnome-thumbnail-factory can't create new thumbnails Status in gnome-desktop3 package in Ubuntu: Incomplete Bug description: the gnome-thumbnail-factory cannot create new thumbnails under Ubuntu 24.04.1 LTS. For example: you download e.g. a .jpg image to desktop and the generic "purple" icon will be displayed. Then got to /home/USERNAME/.cache/thumbnails, and you see the folder fail and inside this folder you find the folder gnome-thumbnail-factory with black icons, this folder wasn't there before you downloaded the .jpg to the desktop. When you change to permission for this .jpg from default 0664 to 0777 the thumbnails will created right now. This solves the problem for this specific .jpg ONLY. I think we have any kind of permission problem on Ubuntu 24.04.1. If I'm wrong with the selected package, please correct it, to the right one. I will bet, that this Bug: https://bugs.launchpad.net/ubuntu/+source/gnome-control- center/+bug/2083530 is related to the same permissions problem, on 20.04.* (last Ubuntu LTS) all was fine. It is a fact that some changes have been made to the permissions of Ubuntu 24.04.1. For example, if I change /var/spool/cron/crontabs/ to 0777 “my_username:my_username”, after the next system reboot it is 1730 “root:crontab” again, and it doesn't matter whether I change the permissions with sudo or su, they are always reset to it's defaults. ########## Basically, the decision to reset important permissions that are necessary for the system to function correctly back to their default permissions is really great and a step in the right direction, but if it means that some processes no longer work properly, that's rather stupid ;-). ########## To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-desktop3/+bug/2086516/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
