Electron CPU usage

@wtidwell Yeah I don’t use those plain black sd cards I buy the more expensive ones because of the issues.

@wtidwell said in Electron CPU usage:
I have this otherone which is a SanDisk ultra 32gb card so maybe that does something.
I looked to see what SD card is in my Pi but all I could come up with is the wrapper it came in. I bought one of those CanaKit’s with everything included. I don’t want to take my mirror down if I don’t have to, sorry.
-
I’m beginning to think it’s the SD card. I did a clean install of Raspian on the SanDisk ultra which is the same class (u1) as the other card which was plain black and it seemed like it was a twinge better but not fantastic. Thanks for your input cowboysdude.
I ordered a SanDisk extreme u3 which will get here tomorrow and try that and report back in. Don’t take your mirror down haha

I hope that’s it. Then we can all laugh about it. Keep me posted.
Just in case:

HOW TO FORMAT AN SD CARD AS FAT Note: If you're formatting an SD (or micro SD) card that has a capacity over 32GB (i.e. 64GB and above), then see the separate SDXC formatting instructions. WINDOWS For Windows users we recommend formatting your SD card using the SD Association's Formatting Tool, which can be downloaded from sdcard.org. You will need to set "FORMAT SIZE ADJUSTMENT" option to "ON" in the "Options" menu to ensure that the entire SD card volume is formatted, and not just a single partition. The updated size will be shown after the format is complete. MAC OS The SD Association's Formatting Tool is also available for Mac users, although the default OS X Disk Utility is also capable of formatting the entire disk. To do this, select the SD card volume and choose Erase with MS-DOS format. LINUX For Linux users we recommend gparted (or the command line version parted). Norman Dunbar has written up instructions for Linux users. -
Ok, this is the kit I bought back in January. I checked my amazon.com history.

That is also where I installed my Raspbian Jessie from. You can install it from NOOBS

Well I just installed everything on a brand new SanDisk extreme u3 MicroSD. And it’s still using all my dang cpu and the transitions are still so laggy.
I think I’ve tried everything at this point.

@Mykle1
Is there anything to do after using the install script? Am I missing some next step? -

You could try this, but I don’t think it’s anything you’re doing or not doing. MM is running, it’s just not running well. I left you another suggestion in the other topic you posted in.
Updating your MagicMirror²
If you want to update your MagicMirror² to the latest version, use your terminal to go to your Magic Mirror folder and type the following command:
git pull && npm install
If you changed nothing more than the config or the modules, this should work without any problems. Type git status to see your changes, if there are any, you can reset them with git reset --hard. After that, git pull should be possible. -
I am having the exact same problem. It is so frustrating.

@TiemenMoesker
I’m really sorry =/ I don’t have any better information for you, maybe you can fix yours. Mine is still busted… -
In details: My mm time is running fine until an animation happens, the time freezes and the choppy animation accurs. When the animation is done the time starts again and it speeds up to the point it should be. Also I noticed that every time the animation happens the CPU jumps to 90+% usage. The pi itself also goes extremely hot.
I bought my raspberry from coolblue.nl 4 days ago.

Have you guys tried allocating more memory to the GPU? I think the default is like 64MB or something. I bumped mine to 128MB a while ago.
One other dumb suggestion: Did you remove the nonessential stuff from your Raspian installs? The Minecraft, Wolfram Alpha, etc. as per the complete setup tutorial?
-
Actually the only thing I did was. Run the auto install command of magic mirror 2 and pm2. That’s it.
-
@bhepler
I’ve done that, both ways giving the gpu more ram and less ram and that doesn’t seem to solve it for me.I did remove all the excess on other installs I did but there’s no other processes running anyway to take away cpu time.
-
@TiemenMoesker Okay, not a problem. This may not free up resources, but it will remove some of the unused programs from the default Raspian image. This is more important with smaller SD cards where space is at a premium.
sudo apt-get remove --purge idle3 java-common libreoffice* minecraft-pi scratch nuscratch penguinspuzzle python-minecraftpi python3-minecraftpi smartsim sonic-pi wolfram-engineThe second option is to increase the amount of memory that is dedicated to the graphics chip on the pi. If you enter
sudo raspi-configfrom the command line, you’ll get a basic configuration window. If you’re actually on the pi, you can go to the main menu ->sudo Preferences and one of the tabs in the pi configuration is the GPU memory allocation. The default is 64MB IIRC. You can bump that up to 128 or 256 and see if it helps with your animation issue.Note: It seems like these suggestions don’t help anyway. Nuts.

Your “Note” says it all…😔

Fresh manual installation of Raspbarian. Running the magic mirror auto install now.
Everything seems fine, but I do get this:
//npm WARN grunt-stylelint@0.9.0 requires a peer of stylelint@^8.0.0 but none was installed. npm WARN stylelint-config-standard@17.0.0 requires a peer of stylelint@^8.0.0 but none was installed. npm WARN stylelint-config-recommended@1.0.0 requires a peer of stylelint@^8.0.0 but none was installed.Is this a (or THE) problem?
-
Same here. I have / had this problem since months. Today I’ve updated my mirror (because it says, there is an update). After this my mirror isn’t usable anymore. The problem is way heavier : I tried very much, but no effects. With MMv1 everything was smooth. I have 2x Raspi 3 - same behaviour.
- Tried Raspi 2 and 3
- deactivated all modules
- fresh installations a few times
- different (sandisk) sd cards
- increase gpu amount to 128/256MB
In MMv2 something changes with the CSS transitions. But I don’t know if that is the problem.
-
For now I wish to know if it’s a problem with the PI or the installation / SD. Because if it’s a problem with the PI, at this moment, I can get it replaced for free or get my money back. My main reason buying the PI was for this project and to kill some time (vacation).
