Invoke Sudo but specify user and password???

I'm working on pushing out a linux executable and have it run silently.

In terminal I just have to type sudo ./nameoffile and then enter the password.

Can I put all of this in one command?

Like $ su admin | sudo ./name of file | passwordforadmin

Which distro do you think is the Flagship of the various Desktop Environments and Window Managers?

We all know that some distro makers have developed their own desktop environment, like Mint making Cinnamon, Elementary with Pantheon or Solus making Budgie, so it's understandable that their distro is meant to be the flagship of that desktop.

But what about the others? A lot of people say that OpenSUSE is the one of KDE Plasma, but with the introduction of KDE Neon disrupts that idea, or despite being stated a spart of the GNU project, GNOME is pretty relevant on Fedora, being that Red Hat has a lot of influence on the project, and also on the [Getting GNOME page Fedora is on the top on the list](https://www.gnome.org/getting-gnome/), plus the fact that Fedora Workstation by default ships with a pretty much vanilla instance of it.

But what do you thing for the others? XFCE, Mate, i3, Openbox, etc.

Comprehensive Kernel 5.1.2 Tuning Analysis

## Intro
I was having difficulty finding information on the performance of the vanilla kernel vs the [`linux-zen`](https://www.archlinux.org/packages/extra/x86_64/linux-zen/) kernel, and how much CPU exploit mitigations (e.g. Spectre) affected performace. In particular I wanted information about general system performance and gaming performance in desktop computers. So I did some testing of my own and I wanted to share the results.

### TL;DR
There is a measurable benefit to both disabling CPU exploit mitigations and using the `linux-zen` kernel, but it's not worth disabling CPU exploit mitigations.

**Disabling** CPU exploit mitigations, compared to the vanilla kernel, using `linux-zen` nets around a +6% CPU/system performance improvement and less than +1% gaming performance (FPS) improvement.

**Without disabling** CPU exploit mitigations, compared to the vanilla kernel, using `linux-zen` nets a +1-2% CPU/system performance improvement and less than +1% gaming performance (FPS) improvement.

## Testing Methodology
I used the [Phoronix Test Suite](https://www.phoronix-test-suite.com/). The two tests I used were `system/gimp` and `pts/unigine-valley`. To disable exploit mitigations I used the Linux boot cmdline option `mitigations=off` which was added in [this commit](https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=v4.19.43&id=8cb932aca5d6728661a24eaecead9a34329903ff). To verify the state of CPU exploit mitigations, I used the latest version (as of today, May 15) of [spectre-meltdown-checker](https://github.com/speed47/spectre-meltdown-checker) from GitHub.

### Hardware and versions
I'm using an Intel 4960K overclocked to 4.4 GHz at 1.3 V with a Noctua NH-D15. I'm using the `cpuidle.governor=teo` Linux boot cmdline option, which was added in the new 5.1 kernel. The graphics card is (unfortunately) an MSI NVIDIA 980 Ti that is not manually overclocked, though its factory clock is 1139 MHz while the reference 980 Ti clock is 1000 MHz. Using [Green with Envy](https://gitlab.com/leinardi/gwe) as a flatpak and running a video game reports that the card runs at around 1300 MHz.

The `nvidia` driver version is 418.74. `mesa` is 19.0.4-1. The `intel-ucode` version is 20190514-1. Both kernels were released today May 15, version 5.1.2.

## Terminology
Vanilla Kernel: The default kernel that comes with Arch Linux.

`linux-zen`: The linux-zen kernel that is essentially the [Liquorix kernel](https://liquorix.net/) but without the MuQSS CPU scheduler.

mitigations on: The tests were ran without any kernel parameters modifying mitigations, after spectre-meltdown-checker verified all

mitigations were in place.

mitigations off: The tests were ran with mitigations off, after spectre-meltdown-checker verified most mitigations were NOT in place.

## Results
### system/gimp (lower is better, measured in seconds)
#### resize
Vanilla Kernel mitigations on: 10.44

Vanilla Kernel mitigations off: 10.21

`linux-zen` mitigations on: 10.39

Vanilla Kernel mitigations on: 14.47

Vanilla Kernel mitigations off: 13.82

`linux-zen` mitigations on: 14.21

### Unigine Heaven (higher is better, measured in FPS)

Issues installing NVIDIA drivers

Hi all,

I am new to Linux and using Linux Mint currently. I am trying to install drivers for my NVIDIA MX150 gpu and when I run the command "sudo sh NVIDIA-Linux-x86\_64-430.14.run" it starts the install but then says

ERROR: You appear to be running an X server; please exit X before

installing. For further details, please see the section INSTALLING

THE NVIDIA DRIVER in the README available on the Linux driver

download page at [www.nvidia.com](https://www.nvidia.com).

I looked around a bit on how to exit the X server, but when I do it just logs me out of my computer and when I log back in and try running it I get the same issue. I am probably missing something stupidly simple but any help would be much appreciated!

How do I successfully install the driver?

My 11 year old son wrote a game in BASH Shell on Linux.

Hi! I'm teaching my son to code. He's 11, so none of that scratch stuff -- we're working in C on Linux. I taught him to write shell noscripts in BASH to make his life easier, and I told him, go write something, anything you want, and I'll get you some chips and ice cream. This is what he came up with. He's getting pretty good, that crafty sod :)

* Fix for CLI offset handling
* Fix monitor sorting issue when using alignment corrections if display order detected badly
* Logging fix, attempt to better log uncaught exceptions
* File handling fixes: handle empty folders and non-image types
* Windows: handle Windows's negative offsets correctly
* Other improvements and changes

## Supported Linux desktop environments / window managers:

* BSPWM (via feh)
