Greetings,

 

On some occasions I realize that one of my cores will stay at 100% even without any applications running. The cooling fan runs at high speed and temperature is quite high!

 

The only way is to reboot. Any thoughts?

 

Michel





A big thank you to everyone who contributes to Bodhi Linux

(This may or may not be relevant to your situation)

I have an nvidia graphics card on my laptop and seemingly randomly I would get that same situation. If I remember right I think it was Xorg maxing out the CPU. When I installed the proprietary drivers for my graphics card that fixed the issue.

As a note, I had the issue on Bodhi 4.x, but not 3.x on that laptop.

Thanks Sef. I have a vanilla Intel card Mobile GM965/GL960 Integrated Graphics Controller  I don't think there are specific drivers are there?

probably not. Let's go a different direction.

 

I think I remember you having a 4 core processor, correct? When you have the issue, type `top` in a terminal. If you have a process that is running at 25%, that would likely be the culprit.

it's a dual core and I have conky showing the processes. I will monitor it next time, but what if it is a main application? Am I stuck?

I'll see if I can figure something out. Does it mainly happen after resuming from suspend or hibernate?

 

You might be able to temporarily fix it by running in a terminal `sudo pkill menu-cached`.

What do you get with these commands?

dpkg -s libmenu-cache-bin | grep '^Version:'
dpkg -s libmenu-cache3 | grep '^Version:'

No it happens at any time. I tried to use the kill comand it did not work, will try pkill. What is menu-cached?

EDIT:

 

According to this bug page, this issue is supposed to have been resolved in version 1.0.2 --

https://github.com/l...-cache/issues/7

If you read about the bug on that page, you will gain a little understanding as to what the libmenu-cache* does. Too much info to post it all here.

 

I'll keep digging and see if I can find anything else.

It seems to me that yes, there are drivers for that. At least there are for Windoze. 

Search for it - find the drivers downloads page, select operating system to see if they have it for ubuntu, download and install.

Have you found out what specifically triggers it yet?

From what I'm reading online every page is always saying "fixed in v- 1.0.2".

 

Can you trigger it by doing an "open with" in pcmanfm? -or- does it usually happen when you're using pcmanfm?

I had this exact problem.  Firefox was lagging like crazy, and when I came here I tried the kill menu-cache command and it was like someone released my computer from a choke hold!

 

What a bug....I guess I won't be simply closing my laptop screen and opening it back up without running that command first.

Update: I shut down and restarted, and the menu-cache spiked the CPU from the getgo.  So, this is running on startup and requires running the pkill command to get rid of it.

It has not happened recently. Tried to tiger it with suspend. Nothing but it is not pcmanfm that triggers it. it usually happens when I open 2 or 3 applications like chrome, thunderbird, etc... and then close them.

More precisely Chrome + Epad. Could not duplicate the problem with Epad on it's own!!!

 

Frankly, I did not manage to duplicate the problem. But it did start when I launched Epad at one point in time. So I don't really know.
