dde-desktop permanently using 12% cpu

[DasJott]

Why is the dde-Desktop permanently using 12% cpu? No matter what I do.

Using Arch Anywhere with newest Deepin.

[hualet]

I think this is not a common issue? @felixonmars @jouyouyun @zccrs

[DasJott]

Fresh start today and around 12% right form the start. Without doing anything.

[hualet]

@DasJott You can help us with:

1. provide a copy of ~/.cache/deepin/dde-desktop/dde-desktop.log or
2. install ltrace tool, run ltrace -Cc -p DDE_DESKTOP_PID in your terminal for a while and hit Ctrl-C, copy the output and paste it here.

Thanks.

[DasJott]

My system while doing nothing. Just started Franz and Chrome Browser and this is what the 8 CPUs are doing: CPUs.zip

The dde-desktop.log is constantly pumped up with one single message:

Warning: "Für den Typ »video/x-rle, layout=(string)quicktime, depth=(int)16, width=(int)450, height=(int)348, framerate=(fraction)25/1, pixel-aspect-ratio=(fraction)1/1« ist kein Decoder vorhanden."

In english:

Warning: No decoder available for type: »video/x-rle, layout=(string)quicktime, depth=(int)16, width=(int)450, height=(int)348, framerate=(fraction)25/1, pixel-aspect-ratio=(fraction)1/1«

There are already 4 files á 20MB and a 5th is growing. That seems to be strange.

Will install that trace tool soon and paste again here.

~6% here. There's nothing in the logs. Here's the ltrace output:

@DasJott I think dde-desktop is trying to create thumbnails for video files on your desktop, and it fails and repeats to do the same thing, you can try to move them to other places?

[DasJott]

@hualet Yeah it does that message every 20-30ms. On the desktop is no video file. There was a mp4 file but I deleted that one. Anyway it had a thumbnail ;)

[hualet]

@DasJott Sorry, video/x-rle is a type of animated picture file or what, I'm not sure, but please find it and try to move it to another place.

[hualet]

@DasJott try this: find ~/Desktop | xargs file --mime-type

[DasJott]

There is no picture file on my desktop. There is a script and two plain text files and two chrome links.

[DasJott]

I tried the find command with a grep for the issued type, but nothing was found.

[zccrs]

Thank you feedback, We have found the cause of the bug.

[DasJott]

@zccrs Is it hard to fix or will it be fixed soon?

[zccrs]

@DasJott Fixed soon.

[DasJott]

You really have to love Deepin to use it even though the fan is running on full speed and the harddrive is getting fuller and fuller if you do not delete the 20MB log files once in a while... ;)

[hualet]

The log files will be rotated.

@DasJott Have you installed the gstreamer plugins? you can try to install them and see if the CPU usages get lower.

[hualet]

Or you can wait for a new version of dde-file-manager/dde-desktop which should've fixed the problem. I just received a message from @felixonmars that he's building the new version.

[DasJott]

I only had the ugly ones left to install, all other "versions" have already been installed. But that didn't make the trick. Same thing, still.

I'm really looking forward to the fix! :) Big THANKS to you!

[felixonmars]

You may also try to install gst-libav :/

[DasJott]

Yes, THAT actually did something! The system is runnign quietly again! Thank you! I was already searching, but didn't know, where to get the missing codec... (whoever that needs).

[hualet]

Great !!! I'll close this issue for now. @DasJott you can reopen it if you get this issue again.

[JulianLai]

Antergos user confirmed this issue, and also confirmed that it had been solved by updating the new version of dde-file-manager.

[DasJott]

There was no update available by then. gst-libav did the trick for now. Am at home now and will try the update of the file manager.

[JulianLai]

@DasJott Maybe you can change the mirror.

[DasJott]

Arch Anywhere uses the Arch repos and AUR. Everything okay. This is all about my Laptop at work and I simply was home already, missing the update ;)
