I’ve been using KDE for years now, and so far, I have not had any issues of this type. Since the last upgrade to 24.04 LTS, my Dolphin fails to show previews. That includes all sorts of images, videos, PDFs, etc.
I have tried:
Turning the settings on and off in Dolphin multiple times:
Installing ffmpegthumbnailer, ffmpegthumbs kdegraphics-thumbnailers kimageformat-plugins libdolphinvcs5 and several other packages based on the advice from internet
Just visiting the ‘VIEW’ menu shows ‘Show Previews’ - and the shortcut is F12… no need for clutter in the toolbar but for sure, there’s so many ways of doing this it’s amazing that OP didn’t trip over them before getting to post.
F10 is standard for the main menus now. CtrlShift, is a pretty standard shortcut straight to settings. CtrlAlt, pulls up the keyboard settings
back on plasma 5 (where i am) and on kubuntu the preview toggle is not assigned to a hot key (at least mine’s not).
but assigning it to F12 would be another way to go… i don’t consider it clutter on the toolbar if its something i use, but would generally just leave preview on since it doesn’t seem to cause much overhead even on my ancient gen 2 intel system.
As something not too often toggled, then I’d stick with the View menu to do it (though I’m good with the F key if I remember next time I want to use it…).
Lots of shortcuts changed, it’s one of the reasons that Plasma 6 upset some folks, but most people tend to agree it’s the best thing to happen to KDE for a very long while.
Most application menus (the dreaded Hamburger) are now relegated to the default F10… but I think that’s juz crazy (better just do Alt_V to get View menu).
I hate to break this to you, but I’m sure that Plasma 5.18 was the LTS release from back in 2020 - and LTS means it would be updated and maintained for a couple more years (usually it’s 4 months).
So right now, there’s 6.1 (3 monbths old now) and 6.0 (6 months old) and the oldest supported version is 5.27 (LTS).
Yeah i definitely feel ashamed for this to be honest lol, yet i wonder if there were any improvements (i cannot allocate big time window and expenses to update now to check myself unfortunately…)
but for sure, there’s so many ways of doing this it’s amazing that OP didn’t trip over them before getting to post.
