Linux needs real-time CPU priority and a universal, always-available escape sequence for DEs and their user interfaces.

For the everyday desktop user, to be clear.

Let's top out the CPU in Windows and macOS. What happens? In Windows, the UI is usually still completely usable, while macOS doesn't even blink. Other applications may or may not freeze up depending on the degree of IO consumption. In macOS, stopping a maxed-out or frozen process is a Force Quit away up in the top bar. In Windows, Ctrl+Alt+Del guarantees a system menu with a Task Manager option, such that you can kill any unyielding processes; it even has Shut Down and Restart options.

Not so in Linux. Frozen and/or high-utilization processes render the UI essentially unusable (in KDE and from what I remember in GNOME). And no, I don't believe switching tty's and issuing commands to kill a job is a good solution or even necessary. You shouldn't need to reset your video output and log in a second time just to kill a process, let alone remember the commands for these actions. You also shouldn't need to step away from your system entirely and await completion due to it being virtually unusable. The Year of the Linux Desktop means that Grandma should be able to kill a misbehaving application, with minimal or no help over the phone.

It could probably happen at the kernel level. Implement some flags for DE's to respect and hook into IF the distro or user decides they want to flip them: One for maximum real-time priority for the UI thread(s), such that core UI functionality remains active at good framerates; another for a universal, always-available escape sequence that could piggyback the high-prio UI thread or spin off a new thread with max priority, then, as each DE decides, display a set of options for rebooting the system or killing a job (such as launching KSysGuard with high prio). If the machine is a server, just disable these flags at runtime or compile time.

Just some thoughts after running into this issue multiple times over the past few years.

Systemd: The Biggest Fallacies

I just came across this [(old) post](http://judecnelson.blogspot.com/2014/09/systemd-biggest-fallacies.html) that highlights a lot of problematic arguments committed by both with / without systemd sides and I think it's a pretty good read. Don't get me wrong, I use to think very highly of systemd, until I came across [without-systemd: Arguments against systemd](https://without-systemd.org/wiki/index.php/Arguments_against_systemd) post that kind of blew my mind and make me, at the very least, be skeptical of systemd, but reading that post puts me somewhere in the middle now.

What's the most compatible graphics card for linux (Fedora/Redhat)

I'm having some bad luck with graphic cards.

​

I originally started with a NVidia card, which sounded like a jet engine (I assume because the OS couldn't manage the graphic card fans correctly?). I've tried downloading and installing drivers for the card but that didn't seem to help much either. I don't think Fedora/Redhat is very supportive of a lot of third-party drivers. The instructions for downloading and installing them were way out of the norm (at least for my level).

​

I then tried an AMD card because I was told those would be more compatible, but it ended up just being a less/difference noise coming from the card fans.

​

Is there any recommended graphic cards for Fedora/Redhat with a minimum of 3-4 HDMI/DISPLAY ports? Something that will work almost out of the box or at least with Fedora/Redhat..

Are there any up to date hardware monitoring softwares like Cpu-Zv, Gpu-Z or Hwinfo64 for Linux ? Desperately nzed help.

EDIT : Probably didn't make it clear I would like a soft with a gui.

I've tried all I could find. Cpu-G, I-Nex, other shady softwares. Everything has something that makes them unusable.



Cpu-G : is installable from ubuntu softwares but doesn't work at all. No gui, nothing shows up even if I see it in activity monitor taking up a load of resources. Then ir crashes.

I-Nex : I've tried any PPA I could find, download, dozens of links expmaining the set up. There are all very old and I"m pretty sure this software is not supported anymore since 2017.

I've really went far in research but found nothing. I don't know what to do anymore and I find impossible to believe there are no 2019 up to date software for that on Linux. And that's why I'm coming to you now as a last resort.

I think the actual reason is because every people wanting that is skilled enough to do it in command line, but I'm not yet, and this still would be pretty useful as a background task in gui for quick checked when running lengthy and intense computations (deep learning).

What I would love is like a small add-on that would enable displaying on the top bar (like some add-on do for activity monitor) as many hardware info as possible like temps, clockage for each components, RPM for fans, etc....

Thanks a lot in advance.

Is Kdenlive really the best there is?

I'm running Debian 9 stable and I'm looking for a video editor with the same (more-or-less) abilities as Sony Vegas Pro, which I used to use when I was on Windows.

People seem to praise Kdenlive for how amazing it is, but I've had nothing but problems. It crashes whenever I try to use one of its 'advanced' features. The kicker: I have 20 GB of RAM. Plus the video cropping in Kdenlive is buggy as all hell.

Da Vinci doesn't like my Intel graphics card/driver, and Lightworks doesn't like Debian 9. Do I really need a whole new OS for this?

Stable Distro(s) With AMD Zen Architecture

Are there any stable distros for the AMD Zen arch? I have been through Mint, Clear, and openSuse Tumbleweed so far and even w/the grub cmd line changes, such as pcie\_aspm=off (reduced, but not eliminated), I get the AER/BadDLLP errors. I'm not apposed to any distro that properly supports the arch.

I have held off on going Gentoo because of the time investment and not knowing if it's going to solve this. I know that the issue is probably relatively benign, but due to the sheer volume of errors (on Mint I was getting approx 6/sec) it is causing hangs.

How to install Unity3d (Tutorial)

**Introduction:**
Hello, my name is Eitan. I am new to linux but i am learning rapidly.
I want to contribute to the community by writing a tutorials for things that might sound easy and unnecessary but for some it might help a lot. if you see that i wrote something wrong please be sure that your write in the comments so i will fix myself.


>!(This tutorial was tested on debian based oses)
!<

**Step 1: Installing Unity3d**
**To install UnityHub go to this** [link](https://forum.unity.com/threads/unity-hub-v2-0-beta-is-now-available-for-download.650455/)

Scroll down to download the latest version.

after downloading right-click on the file and go to properties and then permissions and then make executable.
now just run it and use it.

You may need to install this additional dependency:

sudo apt install libgconf-2-4

**To install Unity3d without UnityHub go to this** [link](https://forum.unity.com/threads/unity-on-linux-release-notes-and-known-issues.350256/page-2)
Scroll down to download the latest version.

after downloading right-click on the file and go to properties and then permissions and then make executable.
now just run it and use it.

You may need to install this additional dependency:

sudo apt install libgconf-2-4

&#x200B;

**Step 2: Installing Visual studio Code (VSCODE)**

**To install VSCode go to this** [link](https://code.visualstudio.com/)

after installing

go to mono project and install mono for VSCode in this [link](https://www.mono-project.com/download/vs/)

sudo apt install mono-devel
sudo apt install mono-xsp4
sudo apt install ca-certificates-mono
sudo apt install referenceassemblies-pcl
sudo apt install mono-complete
sudo apt install mono-dbg

this will fix not auto-completing in unity.

&#x200B;

**Step 2: Adding unity3D addons in Vscode**

First downlad dotnet addon in this [link](https://dotnet.microsoft.com/download)

Second open VSCode and add these extensions that mentioned [here](https://code.visualstudio.com/docs/other/unity)

Debugger for Unity, Unity Tools, Unity Code Snippets, Unity Snippets

&#x200B;

**Step 3: Connect Unity3D Editor to VSCode.**

open unity and go to file -> preferences and change external noscript editor to Browse and then go to
/usr/bin/code or /usr/bin/vscode

&#x200B;

if you got any problems with that try

sudo ln -s /usr/bin/code /usr/bin/vscode in the terminal

&#x200B;

**Step 4: Enjoy**

Now you are ready to use Unity3d without any problems :D

GnuCash vs kmymoney - or any other alternatives, especially with accrual --> cash report capability?

What the noscript says: which one is better? Also, re: kmymoney, what's the difference between 5.X and 4.X? Is there binary support (Windows cross platform capabilities) for 5.X?
