KF 5 & Plasma

kurt · 2015-09-11 07:47:02

OK - This is getting tiresome now. Can anyone suggest a way of stopping kactivitymanagerd from running.

I've tried disabling the service is systemd but that doesn't work.

Every 30 minutes or so it starts again and then I hear my fans start to whirrr as my cpu % starts to rocket and the plasmashell becomes unusable.

I've resorted to not even running the plasmashell and using krunner (alt+f2) to do anything. Not ideal.

kactivitymanagerd can't be disabled, it's a core component of the Plasma desktop.

Has anyone actually reported this? Bugs don't magically fix themselves.

Yeah kactivitymanagerd never acted up here, so it likely isn't going to be easy to track down if it only happens in specific usecases

vipo · 2015-09-11 14:25:44

I am also having an issue with plasmashell and kactivitymanagerd utilizing the CPU constantly. When i check the system monitor, plasmashell is eating 16% CPU and kactivitymanagerd is sitting at 8%.

Any way to fix this? I am using Nvidia drivers if it helps.

OK, I've found a workaround (and quite likely the trigger condition) for this plasmashell CPU usage problem.

Workaround:
You need to disable the Plasma recent document tracking (systemsettings - desktop - activity - privacy - don't track, my system is in Chinese so unsure about the exact wording in English). Then kill and restart plasmashell.

Analysis:
dbus-monitor shows that plasmashell is keep trying to delete the same filename from the kactivitymanagerd database:

I recently used then deleted that file, so it's correct for plasmashell to delete the corresponding record from recents. I've no idea why it keep retrying the seemingly successful call.

So, for those who haven't triggered this bug yet, would you please try delete a file in your recent document list, to confirm this is really the cause? Thanks.

Well, for me, the cpu usage plasmashell problem stopped with 5.4.1.

vipo · 2015-09-11 15:01:29

genericity, your workaround worked, As soon as i selected "Do Not Remember" my CPU usage from plasmashell and kactivitymanagerd dropped to 0.

Thanks a lot for your efforts!

P.S This is with 5.4.1

That sounds like an issue with Baloo, since Baloo is responsible for collecting such data.

@genericity i try your method but isn't working in my case.
It is lstat loop for already deleted file. I found it with strace -p <pid of plasmashell> My workaround is to touch that file and restart the desktop session.

~~Is there a bug report open about that?~~ Found it Bug 352574

Does your file name contain any special characters (brackets, *, etc.)?

Lttp hopping on the plasma. I enjoyed using cover switch with kde4, has it been deprecated in plasma5?

No. First you need to enable it in desktop effects (under a different name?), then select it in window management.

Yes. The parent folder and the file has both [ ( dash and spaces. The folder name itself starts with ( which may be important.

does anyone know how to change this ibus icon?

Update: I've found a solution: change the icon tag in /usr/share/ibus/component/simple.xml

Now it looks better

I am facing some issues that I do not understand:
- First polkit is asking for authorization every time I start a new session, even with the following file:

➜  ~  sudo cat /etc/sysctl.d/90-inotify.conf
#increase inotify watch limit
fs.inotify.max_user_watches = 10000

- Also, The shortcut 'Alt+F1' (which normally shows my dashboard) does not work anymore after a time... and then it is not possible to get it back until I erase all my kde config files. It strange because it happens without me configuring any shortcuts (other than kwin things without alt key involved). However, when clicking on the KDE start icon, it is working...

You are wrong. For some reason, the dev(s) moved "cover switch" from desktop effects to window management. No longer is it under system settings (workspace)>desktop behavior>desktop effects like it has been since 4.1.x. Instead, it is under system settings (workspace)>windows management>task switcher>visualization (breeze is the default). The migration hasn't improved its discoverability in my opinion. Indeed, typing "cover" or "cover switch" in the search field only highlights "desktop behavior", most likely since that was where the functionality used to be located. *sigh*

Sorry if asked before, I googled a lot and couldn't find any information.

Since upgrading to 5.4 (and 5.4.1 too), gtk windows get stuck when I close them. The app actually stops running, but the image stays there, sometimes on top of everything. I also noticed that the plasma panel occasionally gets stuck.

I have an Asus laptop with both Intel (integrated) and Nvidia (dedicated) card, but am using just the Intel one. I already tried all combinations of UXA, SNA, GLX and EGL without difference.

I'm not really sure that this problem just affects gtk apps, but seems to.

I would really appreciate some help with this.

Thanks in advance.

For those who are in need of the File Watch Limit fix that requires a password, I found one fix.

cat /etc/sysctl.d/97-kde-baloo-filewatch-inotify.conf

Then, check to see the number that appears. Remember it, and double it; then use your favorite text editor, I'll choose vim for this example.

sudo vim /etc/sysctl.d/97-kde-baloo-filewatch-inotify.conf

This should fix the limit, and prevent any further messages. If it doesn't simply double it one more time.
I also saw another inotify fix as posted by Ekaradon, but I figured I would post a second solution under the 97-kde-baloo configuration file.

Is it possible to restore KDE4-style "Show widget dashboard"? I mean, when pressing Ctrl+F12 in KDE4 the dashboard was put in foreground. Since it was transparent I could see the resource usage monitor widgets while also peeking at the execution of my program in background. With Plasma5 Ctrl+F12 wipes away all the windows from the desktop, so I can see the widgets but not my program running.

Hi, I want to connect my ssh keys to kwallet manager. I followed these steps in the wiki:

https://wiki.archlinux.org/index.php/SSH_keys#Using_KDM

the problem is that the folder ~/.config/plasma-workspace doesn't exist anymore. Is there a new location?

If it doesn't exist, then create it. It's your home dir.

kwallet is installed and running on my system OK (I think). When I start kontact it asks for my kwallet password and then all my email accounts login OK - So working.

However when I launch kwalletmanger5 it just comes up as a blank window with a title bar (Wallet Manager) and a menu bar (File Settings Help).

If I click File -> Import a wallet - Nothing happens

Any ideas on how I can show my wallet in the Wallet Manager.

Plasma keeps freezing, it's really annoying. Everytime I hear the fans in my laptop going crazy, I know it means Plasma froze. And I have to run "killall plasmashell && plasmashell" in Krunner. I can't stand all those KDE bugs anymore, all the time.
