--- Comment #46 from Marek <marek.schim...@gmail.com> --- I'm sorry, I will open a new bug if needed. I found this one when searching for a solution for my missing thumbnails, it looked pretty similar - and the workaround worked. Anyway, here's the requested info: $ udisksctl info -b /dev/sda1 /org/freedesktop/UDisks2/block_devices/sda1: org.freedesktop.UDisks2.Block: Configuration: [('fstab', {'fsname': <b'/dev/sda1'>, 'dir':

I'm not sure what you mean by the "dolphin's information panel" - I suppose the sidebar with Places / Remote / Recent / Devices? In which case yes, I have the icons there and in general no issues with icons, only thumbnails. I also added "Show Previews" button to the main bar to make sure they were enabled. -- You are receiving this mail because: You are watching all bug changes.
