dde-desktop eating up cpu about developer-center HOT 20 CLOSED

@femans does this happen every time you login in ?

from developer-center.

Hi @hualet, yes I rebooted a few times to see if it persisted and it did. I also killed off dde-desktop and it would put 100% CPU on the deepin-file-manager, and after a while it would go back to dde-desktop.

If you tell me where I can find a log or if I can generate some output, I'd be happy to supply this to help solve it.

from developer-center.

Strange, I rebooted trying to reproduce the problem but get nothing wrong. The log file is located at ~/.cache/deepin/dde-desktop/dde-desktop.log

from developer-center.

So this is the tail of the output;

@femans it seems that the desktop back end is not serving well, it returns nothing every time desktop trying to request for desktop contents.

from developer-center.

There is nothing in the ~/Desktop folder.

dde-desktop-test.tar.gz

Can you build&run this test program and see what does the output say ?

tar -xvf dde-desktop-test.tar.gz -C .
cd dde-desktop-test; mkdir build
cd build; qmake .. CONFIG+=debug; make
./dde-desktop-test

from developer-center.

​desktopLocation "/home/xor/projects"
normal files count 132
hidden files count 39
then follows a list of stuff in my projects folder. Like:
"hidden file /home/xor/projects/fabric is app group : 0"

There might be something wrong with that my Desktop folder refers to my
projects folder.
I wouldn't mind changing that, but I would not know how.

from developer-center.

What does this outputs on your computer ?

xdg-user-dir DESKTOP

from developer-center.

/home/xor/projects

Hi @femans, can you run commands below to help us to locate where causes high CPU usage?

$ sudo apt-get install linux-perf-4.3
$ sudo perf record -a -F 997 -e cycles sleep 5

And attach the generated perf.data when you reply, thanks.

from developer-center.

btw, the desktop also used to display the contents of my projects folder,
but now it doesnt. Also clicking on it, either right or left does not work
anymore. However, there are 2 icons displayed, Computer and Trash, which I
am not sure if they respond. I don't think so.
I didn't look at this, because I never use the desktop. Hardly ever see it.

@femans try this

xdg-user-dirs-update --set DESKTOP ~/Desktop/

hope it can solve your problem.

from developer-center.

@derekdai I know what causes the problem, his xdg DESKTOP is wrongly set to ~/projects/. Caused dde-desktop to request for contents from its back end endlessly.

from developer-center.

@hualet Hi, I tried that, and so far it does not seem to fix it.
In the meanwhile there is a new error in the log output: 07-03-2016, 14:29:25.696 [Error ] [menucontroller.cpp MenuController::showMenuByUrls 131] register menu fail!

@derekdai I hope I don't dump confidential data online now:
perf.data.gz

from developer-center.

@femans No way, I forgot to say that, but you need to logout and re-login after executing the command.

from developer-center.

:/ Could have guessed. Seems indeed to have fixed it :D great.

Anyway, the 2 icons in the desktop have disappeared. I still can't click on
the desktop, so I can't access certain settings. And it might be considered
a bug, that dde eats the cpu when the desktop is not in default location?
Thanks anyway!

Uh..this issue, I don't know how to put it, makes me feel up and down from the beginning to the end.

Yeah, it's a bug indeed. But it's just a bug not a serious fault that can stop me from building the ISO, right ?

Anyway, thanks for you cooperation and fast responds @femans. The community needs ones like you. Thanks 👍

Sure thing! You too thanks for fast feedback :D and great desktop
