Should I dual-boot or buy a separate build for learning linux?

I have a new PC build that is running great with Windows 10.
I've always wanted to learn Linux, so I figured that this would be a good computer to do this on.

I have an additional NVMe harddrive with nothing on it installed, and I figured I could use that to run Linux. (Windows is installed on the SSD that currently holds everything).

I don't want to mess up what is already working great on my system, so I thought I'd ask here before I start the dual-boot set-up.

I could easily get a cheap rebuilt computer w/i5 from Free Geek for like $100-$150 that runs Linux, but I would prefer to use it on my machine that has AMD, Nvidia, etc...

I'm open to suggestions and advice. Cheers!

We are a small team that are here to make a change!

Hey all!

We are a new community launching our own Community-powered Enterprise Linux called "Navy Linux" with focus on minimum hardware requirements.

The focus is enterprise servers for all running CentOS 7 or up today and willing to change when the EOL hits.

​

Currently we are in search of new contributors to our team of 51+

What we are currently in need of:

\-RPM package builders & testers

​

The build has come a long way, we have infrastructure and first Beta release on the way!

Hope to see you on the team!

Cant use node packages from my hdd drive (linux is on the ssd drive)

So a newbie question ...i installed pop Os and i like but i have a problem .. i installed the system on my ssd drive and because its only 120 gb i have to put my react projects on the hdd drive ...

Suggestion

We should change r/linux for support questions. Bulk of the posts are support requests. Its understandable that anyone searching for linux or curious about it is going to want to post here without reading the rules.

We can change actual info about Linux in general to a different name. Us creative bunch can come up with an alternative.

multi-monitor layout/detection not persistent (docking, displaylink, kde)

Hello,

* Context :

I have a dock labelled DisplayLink, 4HDMIorDP (actually DVI under the hood) to USB-C PD charging. So I use it with 4 external monitors and the internal monitor. I'm running Kubuntu20.04, on a laptop with an Intel iGPU and nVidia dGPU.

​

* Problem :

**When booting on with my dock plugged in, the external screens stay black.**

Then, calling `$ arandr` GUI, I have to go to the "Outputs" tab, and activate each of the four DVI-I-M-N (M and N belonging to {2,3,4,5} and {1,2,3,4} respectively), by clicking the validate icon.

It then spawns all of them but in a mess, and I have to re-arrange them through the Display Configuration Utility in KDE (`$ kcmshell5 kcm_kscreen` CLI if one is too lazy to search for it in the app menu GUI).

But at each reboot it get back to the external blank screens.

​

* Trials :

Previously on another machine I used to launch a bash noscript at each session startup, doing `xrandr <my chosen arrangement>`. However i'm not at this step yet, and I first would like to get all my screens active at each reboot.

Here [https://wiki.archlinux.org/index.php/DisplayLink#Enabling\_DVI\_output\_on\_startup](https://wiki.archlinux.org/index.php/DisplayLink#Enabling_DVI_output_on_startup) they say to add such command to the startup configuration `$(xrandr --listproviders | grep -q "modesetting") && xrandr --setprovideroutputsource 1 0` && the same goes for up to the n-th screen to wire to the source `0`.

However in my case,

me@tpkub20:/etc/X11/xorg.conf.d$ xrandr --listproviders
Providers: number : 6
Provider 0: id: 0x47 cap: 0x9, Source Output, Sink Offload crtcs: 3 outputs: 5 associated providers: 5 name:modesetting
Provider 1: id: 0x15b cap: 0x2, Sink Output crtcs: 1 outputs: 1 associated providers: 1 name:modesetting
Provider 2: id: 0x139 cap: 0x2, Sink Output crtcs: 1 outputs: 1 associated providers: 1 name:modesetting
Provider 3: id: 0x117 cap: 0x2, Sink Output crtcs: 1 outputs: 1 associated providers: 1 name:modesetting
Provider 4: id: 0xf5 cap: 0x2, Sink Output crtcs: 1 outputs: 1 associated providers: 1 name:modesetting
Provider 5: id: 0xd3 cap: 0x4, Source Offload crtcs: 0 outputs: 0 associated providers: 1 name:modesetting
me@tpkub20:/etc/X11/xorg.conf.d$ xrandr --setprovideroutputsource 0 0
X Error of failed request: BadValue (integer parameter out of range for operation)

me@tpkub20:/etc/X11/xorg.conf.d$ xrandr --setprovideroutputsource 1 5
X Error of failed request: BadValue (integer parameter out of range for operation)
Major opcode of failed request: 140 (RANDR)
Minor opcode of failed request: 35 (RRSetProviderOutputSource)

Serial number of failed request: 20
Current serial number in output stream: 21
me@tpkub20:/etc/X11/xorg.conf.d$ xrandr --setprovideroutputsource 5 0
X Error of failed request: BadValue (integer parameter out of range for operation)
Major opcode of failed request: 140 (RANDR)
Minor opcode of failed request: 35 (RRSetProviderOutputSource)
Value in failed request: 0xd3
Serial number of failed request: 20
Current serial number in output stream: 21

Three things are strange :

1. Provider 0 which is supposed to be my Source Output (internal screen) has `name:modesetting` instead of `name:Intel` (as in [https://wiki.archlinux.org/index.php/DisplayLink#Setting\_up\_X\_Displays](https://wiki.archlinux.org/index.php/DisplayLink#Setting_up_X_Displays) or [https://github.com/AdnanHodzic/displaylink-debian/blob/master/post-install-guide.md#display-detection](https://github.com/AdnanHodzic/displaylink-debian/blob/master/post-install-guide.md#display-detection) ) or something

nVidia related.
2. Provider 0 is associated to Provider 5 instead of being associated to itself, as on the URL examples. I actually don't even know what is Provider 5, but it's written `Source Offload` in contrast to `Sink Output`, so maybe it's the dock entity...
3. When wanting to properly rewire the external displays onto the internal source, shell complains, although it doesn't in the above links.

&#x200B;

* Questions :

1. How to get rid of those `--setprovideroutputsource` errors ?
2. How to get my monitors detected at startup ?
3. Is there a way to spin a daemon that executes either [noscript1.sh](https://noscript1.sh) or [noscript2.sh](https://noscript2.sh) depending on whether I plug or unplug something to a given USB-C port of the laptop?

Where is /dev/root coming from?

df lists my / filesystem as being /dev/root

/dev/root 62882820 9328056 53554764 15% /

In fstab it's configured thus:

/dev/sda1 / xfs noatime 1 1

But there's no such device in /dev.

root ~ # ls -l /dev/root
ls: cannot access '/dev/root': No such file or directory

I'm running LFS 10.0 systemd linux-5.8.3.

General doubt and skills required for a custom build

I'm a linux noob and just started learning coding and ethical hacking. I've read on some forums that kali linux has an "insecure" build to allow maximum number of pentesting tools, is it true?

Right now i'm using debian on an old thinkpad but i plan on buying a laptop with a dedicated gpu in the coming months. What skills do i need to make a custom linux build? It's going to be debian based, for gaming as well as pentesting. And is such a build practical at all?

have you noticed there don't exist any good old distros of linux

I always thought that was a weak point of linux. it has the ability to run on very old (100mhz / 32mb ram) hardware but doesn't really exist for it in any meaningful capacity.


I think windows 95-98 had thousands of games and programs compatible for it along with hardware support. But as far as linux distros for mid 90's machines..... you got maybe the long abandon puppy linux but thats it.


I'd be rediculously interested in seeing old hardware run new software as a retro pc enthusiast. But it pretty much just never existed in the linux universe it seems.

Control LIFX devices in terminal

Hey all, I'm not sure if this is a place to share this. Mods, please let me know and I'll remove if so.

&#x200B;

Anyway, I'm exceedingly lazy and sometimes can't be bothered to use my phone to control my LIFX light, so using the wonderful api from https://github.com/mclarkk/lifxlan, I threw together a tiny python noscript that you can drop in .local/bin and use to control your light. (Note, this is essentially designed for one light, but of course I could expand this since the wonderful python library supports it.) Cheers!

What are some way I can improve the performance abd make it to where I can watch YouTube? Do I have to change to an even lighter OS or is there another way?
