startdde needs more than 25% cpu

[LinuxUserGD]

I'm running Antergos Linux 15.5 Desktop 64 Bit with Deepin.
While I don't have any other programs open, the deepin system monitor shows ~30% cpu usage (25% from startdde). I've tried to kill the process which ends in a black screen.
Is there any workaround to reduce the cpu usage?

Same problem : 12,5% with core i7

[LinuxUserGD]

Core i5 with Intel Graphics 620 (OpenGL ES 3.0 mesa drivers). Would I get a message from the system if it uses software rendering? I changed the distro to Budgie and now the CPU is at 2% in the deepin system monitor while I'm still running other deepin apps like the file manager / terminal. Does 25% and 12,5% mean that it runs 100% in one thread / on one core?

[ghost]

Same problem, 100% usage on core i7 7500u

[OmarEmaraDev]

The same happening with my Ryzen 7 1700. Startdde is taking up 6.2% which is exactly one thread from the 16 threads I have. There is another report with the same issue here.

@electricface @jouyouyun

Here is perf data and startdde journal.

[maxcruz]

After starting the session on Arch Linux startdde consumes the 100% of the CPU

[DasJott]

Arch here too. Core i7 7th Gen.
startdde sometimes takes up to 100% CPU

[jouyouyun]

@ekhaled667 download the file, then copy to /usr/bin/startdde and exec chmod +x /usr/bin/startdde, then reboot.
If the bug ocurred again, please update perf.data and dde.log, thanks!

[ekhaled667]

@jouyouyun
The problem persists.
Here is the new log.

Actually, it's wrose now. My dock won't load, reverted the file and it still won't load... how can i fix this?

EDIT: Fixed, it was a problem with how i was extracting my backup file. Sorry.

[DasJott]

I also experience that sometimes. Dock sometimes takes minutes to appear on screen. With normal version.

[epoiate]

Yeah, I fixed it already. It's normal for it to take a few seconds (I'm using a SSD), but in my case it wasn't loading at all. A lot of things wasn't working too.

[DasJott]

Using SSD here too. Precisely it is a Dell XPS13 here. And it still sometimes takes minutes.
Also while runtime dde-session-daemon jumps up to 400% which drains battery big time. I don't know, if that is related...

[jouyouyun]

@ekhaled667 always keep a high cpu usage?

[ekhaled667]

@jouyouyun Yes, Always.

[snyh]

@ekhaled667

Run this command strace -t -f -p $(pgrep startdde) 2>dde_strace.log when startdde's CPU usage is abnormal. Run it about 5 seconds is enough.

All of perf.data above hasn't too many information to show the problem.

[epoiate]

@snyh
Here is my results
dde_strace.log

PS: startdde is ALWAYS using a full core of my 6600K

[snyh]

@epoiate The strace's (syscall) log hasn't any problem.

Please wait a moment, @jouyouyun will build and upload a startdde with golang perf enable.

[epoiate]

@electricface can you elaborate the exact steps that I should take?

[OmarEmaraDev]

@electricface @jouyouyun Is there an update on this? The problem is still there and such CPU usage getting tedious.

[Alpkant]

This problem is happening to me as well and if i kill the startdde from htop, it restarts the environment and i log again and cpu usage returns to normal values. However lot of time it uses 100% of the one of my cores until i kill the startdde.

[jouyouyun]

Try to edit /etc/default/grub to add parameter vsyscall=emulate, then exec grub-mkconfig -o /boot/grub/grub.cfg to update, then reboot.

[Alpkant]

@jouyouyun I didn't see any high usage after editing grub file. Thank you.

[ekhaled667]

@jouyouyun It didn't work for me.

By the way, I'm on Arch Linux not Deepin OS.

And I don't use GRUB, I use systemd-boot.

[OmarEmaraDev]

@jouyouyun Same here, that doesn't work. Arch Linux and don't use GRUB.

[DasJott]

Arch with grub here and it mostly works, but not always.
Mostly it is on new startup, where it runs 100% of one cpu. After logout and re login it runs normal.

[jouyouyun]

😓
How repetition this bug?

[ekhaled667]

For me, It's always utilizing one thread.
Even if I log out and then log in again, in 5 seconds it starts using 100% of one thread.
Even if I kill the process.
Even if I reboot.
Not once did it not utilize the thread.

[msusenburger]

Had this issue the last month at least. Changed today from launching via startx to launching via lightdm and issues seems resolved for me.

[OmarEmaraDev]

It is always happening for me as well. Always utilizing one thread. Tried rebooting, killing and restarting and nothing worked.

[jouyouyun]

Have you install gnome-keyring?

[jouyouyun]

Try this startdde, downloaded and chmod +x, then copy to /usr/bin/startdde.

Note: you should update your system firstly, startdde version should be 3.1.29-1 after updated.

[LinuxUserGD]

I've updated to 3.1.29-1 on Arch Linux without the patch and it works for me 👍
The deepin system monitor shows around 3% cpu usage.

[msusenburger]

Version 3.1.29-1 is also working in my case, even after launching with startx.
gnome-keyring is installed in version 1:3.28.2-1.

Thanks for fixing 👍

[OmarEmaraDev]

Just tried the previously mentioned startdde file. It seems to be working fine now. Thanks !

[ekhaled667]

Try this startdde, downloaded and chmod +x, then copy to /usr/bin/startdde.
Note: you should update your system firstly, startdde version should be 3.1.29-1 after updated.

This worked for me too, thanks for your time.

[jouyouyun]

Fixed in startdde 3.1.30, please update!

[Stakdek]

Running on Ubuntu 18.04 I can't update startdde to 3.1.30. It stops at 3.1.28-1. I have the same high CPU issue. @jouyouyun
