Best study materials online?

Want to study for LPIC-1 cert for my new job but not feeling very confident to start there so maybe I'd just go with Essentials first just to get a solid ground.

Looking for the best online materials to prepare for the exams.
I know about Linux Academy but can't for the hell of me login into the LA portion of the site- it just displays the head scratching penguin picture. I'm registered on cloud guru and can login there but kinda confused if the courses and the subnoscription between the two sites is shared/same. Just don't get the whole situation with the two sites in general.
I've Downloaded the LA app and unable to login there either but can see the courses list and for example LPI Essentials course duration is listed as 26h in the app but 16h on the Cloud Guru site for the same course with the same teacher, which adds even more to my confusion. Would like to know for sure before I subscribe.
(I've seen some complains about the quality drop for the Linux Academy courses recently though. Are there better options out there?)

I also use Udemy and already got the Linux Mastery: master the command line in 11h course but dunno if it's gonna prep for the cert exam, plus I think I need some practice tests anyway. Found this Jason Dion's Essentials course which is now on sale for me and does have tests, is it any good?
Not so many LPIC courses on udemy I guess.

Discussion Icons and UI design on Linux

Hi everyone,

I have been using Linux for some time and have been impressed by the high degree of customizability of modern desktop Linux. One thing that I particular liked is the ability to modify themes and icons to my liking. This is also something that used to be popular back in the XP days, but had became much less so on Windows 10. It is one of the reason that drives me towards Linux.

However, in the past decade (?), I have noticed there is an increasing usage of using bland, monochrome and symbolic icons in many Linux software. For comparison, pic below is from ubuntu 10.04 from \~10 years ago, look at all the colorful icons:

Pic below is my gnome 3 desktop today, which I have reset to default icons:

You can also see many applications, e.g., Firefox, GIMP, nautilus, all use monochrome icons by default.

While it is true that many of these applications can be themed, one question remains: why developers do not want to use colorful, realistic icons that used to be ubiquitous long time ago, instead, choose to use monochrome icons which is rather "dull" and "unaesthetic" (my opinion) as default? I'm sure there are public domain icons that are well-designed and look much "better" than these defaults.

I think having a bright, colorful interface is important in terms of user experience, which is equally important as the actual functionality. I hope more developers can realize this and make use of "better" icons, or at least provide theming support for their software.

Single cgroup memory limit for both hugetlb and non huge pages?

Hey, i am fairly new to cgroup, I understand in cgroup v2, it has a separate controller for hugetlb, but the memory controller still only tracks the non huge pages memory. Is there a way to have a combined limitinbytes for all the memory (including both huge pages and non huge pages) a cgroup can use?

Should I switch?

I want to switch to Mint from windows 10 on a 4gb intel i3 computer for speed options and overall just easier browsing, but my problem is I use some apps that just aren’t on linux.

I use adobe apps like premiere pro, media encoder and photoshop and I use screenwriting apps. I know there are good alternatives but I’m just not sure if I should switch.

Can't tell if I'm using llvmpipe or Nvidia.

I'm currently running Ubuntu 20.10 and I wanted to try out Wayland even though I know that XWayland apps won't run with hardware acceleration yet on my GTX 1070. I looked up tutorials on how to prevent Wayland from being blocked when using an Nvidia card and I'm currently writing this post from a Wayland session.

I have a dual monitor setup. Both are 27" but one is UHD and the other is QHD so I have 150% scaling on the UHD monitor. Everything looks crisp and it's a much better experience than I'm use to on Windows or X11...but then I checked the About page in Gnome Settings. It says I'm running in Wayland but under Graphics its says llvmpipe (LLVM 11.0.0, 256 bits).

When I first started using Linux back in October, I had trouble installing Nvidia's proprietary drivers for whatever reason and I would constantly get set back to llvmpipe. I don't remember it supporting high resolutions let alone two high resolution monitors. Not only that but all animations are smooth and CPU usage is only at 3 or 4%.

I can only assume that Gnome is incorrectly reporting that I'm using lllvm. Has anybody else experienced this?

Spotibar - An improved Polybar/Spotify integration

Hey everyone!

&#x200B;

I was really annoyed at all the existing Polybar/Spotify integrations as they didn't allow me to heart songs on [last.fm\](https://last.fm) or add songs to playlists easily which I've always found difficult so I never really made playlists. This plugin should address these issues as well as doing something I haven't seen in other Polybar plugins - adds a popup config window. This window pops up a tkinter window above where you right click on the polybar module and lets you set some config options. If focus moves to a different window, the popup closes.

&#x200B;

Posting this here so people can see this way of making config/popups with Polybar. Seems like a useful improvement for UI options in almost all Polybar plugins!

&#x200B;

I'd really appreciate if people checked it out and gave me some feedback to improve it in any way possible! Check it out [here\](https://github.com/conor-f/spotibar)

no keyboard, trackpad, touchscreen

My keyboard, trackpad or touchscreen are unresponsive after GDM. Oddly enough, this is not every time. Sometimes all will work, sometimes none, sometimes only one.

As of posting, my trackpad and touchscreen are unresponsive. I've posted the dmesg output. i2c_hid i2c-SYNA329A is the trackpad and i2c_hid i2c-ELAN2514 is the touchscreen.

I've tried an LTS kernel, but didn't make any difference.

Thanks very much for any help.

dmesg

[ 1.845203\] i2c_hid i2c-SYNA329A:00: HID over i2c has not been provided an Int IRQ

How could I write instead of "\^..." to get the 3rd character?

Linux Graphics: AMD vs. Nvidia pros & cons?

Trying to figure out which way to go on a new high-end build: GeForce or Radeon.
Someday, in the event GPU's become available again, I plan to get a new one.
And an entire computer actually. Threadripper or Ryzen and higher-end stuff over all.


But I'm a bit torn on AMD vs Nvidia for the GPU.
I'm a content creator, and I also game on Linux and Windows.
I primarily use OBS-Studio, Kdenlive or Flowblade, and Inkscape/GIMP.
BUT, I also might consider moving towards premium editors like DaVinci Resolve or Lightworks.
I'm also toying around with Natron2, but I could eventually move to Blender.


All of my better GPU's have been Radeon, but I'm currently getting by on a lower-end Nvidia Quadro.
I know AMD's official drivers are open-source, and they've often been praised for good performance in more recent times. But in the past some games have been Nvidia-centric especially on Linux. Alien:Isolation was unplayable with my R9-290x on Linux because it was Radeon.
NVENC is pretty useful in OBS-Studio, but I imagine with lots of cores/threads going back to x.264 would be fine, or I could use VAAPI with Radeon.
Would love to hear any thoughts on what I'd gain/sacrifice with one vs. the other currently with Linux.
Cost/value isn't necessarily a concern.
