KDE Plasma thumbnails not loading and Compositor crashes

saurabh000345 · 2020-12-10 19:01:34

I recently tried moving .local to my main NTFS shared data partition and linking it in my home directory. That didn't go as intended. I think I resolved most of the problems and managed to restore the state. Suddenly Dolphin refuses to show or even generate thumbnails. .thumbnails and .cache/thumbnails aren't even created, and if they're manually created, the file manager fails to populate it. I have visited forum posts and none of the solutions seemed to work, in fact most of their "fixes" were already installed/configured. Although, thumbnails for some files (I'd guess they're in some size range as not all of them are displayed) are indeed displayed when the file manager is summoned from the browser for example.

I have the preview limit set to "No limit"
I have ffmpegthumbs installed.
I have tried using Thunar, so it's not an issue only with Dolphin
I have reinstalled ffmpegthumbs
I have tried deleting .thumbnails and .cache/thumbnails (I didn't verify if they existed before issuing the commands)
and yes I have tried rebooting my computer.

Secondly KWin crashes are getting a little too frequent which stops the compositor. [This is an aside, my main issue is the thumbnails at the moment. Afterall, this is just an added hassle]

That's just a bad idea to do, unix programs expect unix permissions and symlinking and the like and there might be things that rely on case sensitivity. Is the "restored" state back on a POSIX filesystem? What are the permissions? They need to be 0755 for folders and 0644 for "most" files and they have to be owned by your user and a group that user belongs to.

What are the permissions on these directories you are talking about, post a

stat $file

for each of them e.g.

stat .local .cache .cache/thumbnails .thumbnails

Yeah I guess I know it for sure now.

I think the permissions aren't messed although I made the folders myself. My PopOS system has the same permissions set. The folders are owned by me, I had a cringy username so I replaced it with <username>

Also, .cache/thumbnails has been populated but the thumbnails still don't load. I'd guess it's for when the file manager is summoned by the browser. You guys will obviously be able to help me better.

Nobody's got anything to say?

Check journal and/or strace dolphin to see why it has issues accessing the thumbnails.

I'll mark the thread closed. I deleted my .local and it solved my issue.

Alright, I'm reverting the change I made then. Wouldn't want it deleted, but I won't be able to take it much further either. I'm sorry I didn't know [CLOSED] had that significance.
