A workaround for Google Chrome high CPU usage in background. (Ubuntu, Fedora)

I conducted a simple test which shows that Google Chrome disregards window focus changes.

**Prepare**

1. In tab 1 open a page that uses significant resources (RAM, CPU). A high resolution YouTube video is a good example.
2. In tab 2 open an empty tab
3. Open any system monitor like HTOP
4. Open an empty workspace/desktop.

​

**Case1**.

1. Focus on YouTube page, let the video play (tab 1).
2. Switch focus to the empty desktop/workspace (chrome should not be visible).
3. Observe that there is no significant change in CPU consumption. In my case it's 50-60%.

​

**Case2**

1. Focus on YouTube page, let the video play (tab 1).
2. Switch focus to the empty page in Chrome (tab 2).
3. Switch focus to the empty desktop/workspace (chrome should not be visible).
4. Observe hat CPU usage is significantly reduced almost instantly. In my case it's 10-20%.

I could reproduce this test on Fedora 30, Ubuntu 18 and 19 all running Gnome.

​

**So what ?**

This has one important implication for users who like to play music in the background via YouTube. If high CPU usage bothers you, you need to be sure that you don't leave Chrome on a resource intensive webpage before switching to another application. If you have a fast hardware you might not even see significant difference in CPU usage between the two cases.

I have tried the same test on OSX and could not reproduce it there. I assume that it is related to this issue [https://bugs.chromium.org/p/chromium/issues/detail?id=821820](https://bugs.chromium.org/p/chromium/issues/detail?id=821820). Provided that it's not likely to be fixed soon, it's probably a good idea to have an extension (in Chrome or Gnome) that somehow fixes this.

Debian 10.x is doing different things to cifs mounts then 8.x.9x



not strong on linux, been using a cifs mount from OMV for 4 years no problem. cifs server is 9.x

this is the mount command

mount -t cifs [//10.55.55.2/Media](https://10.55.55.2/Media) /home/user/mount -o user=cifsuser

on 9.x this is what it mounts as.

[https://i.imgur.com/TeBHiwd.png](https://i.imgur.com/TeBHiwd.png)

on 10.x same exact mount command.

[https://i.imgur.com/buHpKVT.png](https://i.imgur.com/buHpKVT.png)

thus no one but root has write permissions, no does it indicate the extra smb permissions "+"

ok i learned i had no write permissions on any of the os's which now makes sense, i needed to create a group with a gid of 1002 and add the user to it, that worked on 9.x but it appears 10.x is not importing the acl information????

any help would be great!

Are there any all-in-one references, cheatsheets you'd recommend? (Ubuntu cause I'm such a noob)

Well, I'm kinda new to that. Not completely though, I know about bash a little and I did some basic server management before, but just using tutorials on the internet.

Now I've got a personal project without strict time restrictions and I have a willing to do everything the right way... well, at least in a better way than before. I don't want to constantly google pretty specific queries, which solve the task, but doesn't make me learn any faster.

Sorry for that long ass intro. How do people actually learn Linux? I've got this [bash reference](https://gist.github.com/LeCoupa/122b12050f5fb267e75f) which helped a lot back then, are there similar references for Ubuntu specific tools and commands? I want to have somewhat decent knowledge on managing Linux through terminal. Like managing users, permissions and that kind of stuff.

Sorry for not being brief on such a basic topic, but really don't know how to compose it any better. Thanks :)

Asus Fonepad (K004 ME371MG)

Hola! Tengo una tablet Asus Fonepad (K004 ME371MG) y me interesa saber si es conveniente instalarle un sistema operativo que no sea el Android 4.1 que trae de fabrica. Por ejemplo, se me ocurre pasar a instalar un Ubuntu. Es posible o no, y que tengo que ver antes de hacerlo.

Dejo las especificaciones técnicas:

Request: What specifically would you like to see more guides on?

**Background** \- I'm hoping to make a career change into Linux, land a decent tech gig.


I've started a blog writing guides *(won't link, if you want to find, you will)*


I'm seeking ideas on what you think, would be nice to see more of. Something a little niche and any tips you have for a young man looking to jump from Construction to the terminal.

Always open for feedback - *I need this break from cutting wood everyday*.

What Terminal Emulator do you use and why?

Seeing all of the different terminal emulators out there, I am paralyzed by choice.

What are the benefits to all of these emulators, and what makes you use the one you are using?

Is it just because it came with the distro you daily? Is that how most people pick their terminal emulator? Or is there actual things you guys look for?
