A new community update! New hardware to announced and previous hardware to return!

Hi,

by doing a

ps aux | grep UserName

The output do not keep the LF[^1] 😡

I've found some solution online by they involve 3 or more pipe | !

On my side, I've made this

ps -fp $(pgrep -d, -u UserName)

But still I found it not super human readable.

Is their a native way with ps to filter users ? or to grep it but the keep the LF ?

I know there choice of distro is really meaningless as you can install almost any program on almost any distro. But I have been playing with kali which is for security people and pen testers. Is there a similar distro for programmers? Like a few ides installed some profiling tools some virtual environment tools etc?

Update to this post. Please read it before commenting!

So I ended up following instructions I found online and disabled secure boot in my BIOS and then tried to boot Linux Mint (version 21.2, Cinnamon Edition) with UEFI OS. However, as soon as I did that, i got a "Perform MOK management" screen that said the following:

Continue boot Enroll MOK Enroll key from disk Enroll hash from disk

Can anyone tell me what this means and what I should do? Do keep in mind I'm a total newbie when it comes to Linux. Thanks in advance!

So I've been really interested in immutable OS's since Silverblue, kept jumping off and on again as I hit what I thought were brick walls. I was just not approaching them properly.

I've been using Bluefin for work for the last 6 months and started making distrobox containers for projects. One thing I always ended up with was a load of mess with pip or NPM, so the idea I can just jump into a container for that specific project was really appealing.

But it never occurred to me, I can do this for everything, I know this is something that has been done before, but I've just stumbled on it. I made a distrobox container using boxbuddy that used the arch-bazzite-gnome image, called it arch-gaming. This has given me a containerised gaming setup that runs like arch native. I can just chuck all my gaming stuff through that and box buddy auto exports the icons into the app menu, so the GUI side of things is sorted. As it's bazzite the nvidia drivers and steam are all ready to go I installed lutris that was it.

The added bonus of bluefin is that I don't need rpm-ostree for anything, languages are handled by brew, apps with flatpak, and now the aur for anything niche or apps I want to use in a more traditional setting.

I now have a portable, reproducible system that should be pretty robust.

It started as a stupid project cause I was bored. How much can you actually do without a windowing environment?
After finding out how to post to lemmy from a TTY, I realized that I can do most things I do daily using text.
Browsing the web in links, which opens all sorts of files in the corresponding programs if configured correctly.
Opening images in fbi, PDFs in fbpdf, listening to music in cmus, watching movies in mplayer, using e-mail in alpine, creating documents in vim and latex, ...
The only thing that still requires a GUI is image editing and a few websites I need that don't work without JavaScript.
And it's actually really nice...more focused, without loading times, animations, popups, ads, or other distractions, and everything is scriptable.

Anyway, sorry for the blog post.

is there a way to prevent all the other apps on the system from opening up new tabs/windows in firefox?

I'm using EndeavourOS (Arch btw) with KDE plasma 6.x (Wayland), SDDM, and systemd as boot manager. I have 2 displays, one HDMI-A-1 (1080p) and one on DP-1 (Ultrawide).

When I boot the password entry cursor defaults to the HDMI display, but I want it to default to the DP-1 display.

I've tried a few things, mostly suggestions from ChatGPT. But nothing has worked. The weird thing is at boot the boot menu and boot messages all appear on DP-1, and it is set as primary in KDE and that works fine as well. It is just the logon prompt that defaults to the wrong display.

Things I've tried so far.

• Adding video=DP-1:e to the options in the systemd entry - (No effect)
• Edited /etc/sddm.conf.d/wayland.conf to run a script that did the following: kwriteconfig6 --file startkderc --group General --key PrimaryScreen DP-1 (didn't fix it, actually broke the logon process so had to remove it)

I'm just not familiar enough with how SDDM works so hoping for some good pointers to provide the answer or point me in the right direction.

Hi all!

I have a Debian stable server with two hdds in a md RAID which contains an encrypted ext-4 filesystem.

I'd like to migrate that over to BTRFS to make use of deduplication and snapshots.

But I have no idea how to set it up since BTRFS has its own RAID-1 configuration. Should I rather use the existing MD array? Or should I take the drives out of the array, add encryption and then add the BTRFS RAID inside that?

Or should I do something else entirely?

Hi,

I've seen some tutorial to create EdDSA key with Gnupg

gpg --full-gen-key

and it's supposed to allow me to create ECC key, but I see only

Please select what kind of key you want:
(1) RSA and RSA (default)
(2) DSA and Elgamal
(3) DSA (sign only)
(4) RSA (sign only)
(14) Existing key from card
Your selection?\

gpg --version show:

...
gpg (GnuPG) 2.2.27
Supported algorithms:
Pubkey: RSA, ELG, DSA, ECDH, ECDSA, EDDSA
...

Any idea what's wrong ?

So, I discovered weird behavior when trying to play games on an NTFS file system in Linux.

When i auto mount the drive through a fstab entry, it is only able to launch Linux native games (I think I read somewhere that this is a permission issue).

However, if I mount it through steams "select a drive" option, it works without a problem (so far at least).

I assume this is again a permission issue, as when I mount the drive through steam, I get a Polkit password prompt.

Anyone got a clue what's going on, and/or maybe a way to make the auto mount work, so I don't have to manually mount it after every boot?

Distro:

Arch

Kernel (according to neofetch):

Hey y'all, today I experienced another push for Linux from our friend Microsoft. 5 minutes ago, I wanted to use the timer app on Windows, so I could manage my work/break schedule, and this fucker showed up. Yes, that's a prompt to sign in with a Microsoft account to use the clock. If you close it, it pops up 30s later. Clicking “Don't sign in” or closing the process responsible for displaying it is useless, and guess what… IT PAUSES THE TIMER WHEN IT SHOWS UP.

I guess this is another thing added to the super long list of things which will eventually make me switch my main workstation to Linux once win10 is discontinued.

/endrant

Hope y'all are having a great day :3

I've noticed a general sentiment that printing on Linux is (or at least was) extremely cumbersome and difficult. Why is that?

Hi,

I would like to use Gnupg to encrypt, sign... documents.

I've downloaded the Manual, it's quite extensive. So the learning curve is proportional :)

I've tried the GPA GUI, but with it, it seem impossible to generate an ECC key..

So what would be your recommendation to be able to generate ECC keys, be able to encrypt, sign etc.. with or without GUI.

Thanks.

To sum it all up, I was looking to completely migrate from Windows 10 to Linux Mint (version 22, Cinnamon Edition). I followed an installation tutorial on YouTube, flashed the ISO to a bootable flash drive using balenaEtcher and booted Mint in my notebook. Something went wrong during the installation though: I tried to go a few steps back to review my options, and when I tried to proceed again I was met with this error:

ubi-partman failed with exit code 10

It seems it means there was a problem with partitions (I selected the option to wipe Windows and replace it with Mint in the installer), so I quit Mint and tried to boot it again so I could redo the installation. However, when i tried to boot it again I was met with this error:

Failed to open \EFI\BOOT\mmx64.efi - Not Found Failed to load image ??: Not Found Failed to start MokManager: Not Found Something has gone seriously wrong: import_mok_state() failed: Not Found

So essentially, since my Windows 10 system was wiped, I was left without an OS. So I looked up the error and it seems it's because version 22 of Mint doesn't have MokManager (don't know how it booted the first time then, but okay), so downloaded the ISO for a different one (version 21.2, Cinnamon Edition) that does have it and flashed my flash drive with it (on a different laptop, since mine was wiped.) When I tried to boot it to my laptop, I was met with yet another error:

Verifying shim SBAT data failed: Security Policy Violation Something has gone seriously wrong: SBAT self-check failed: Security Policy Violation

Now, it seems this will be solved by disabling Secure Boot in the BIOS. However, I'm a bit aprehensive on disabling Secure Boot, since the laptop I used to flash the OS into my bootable drive is a very, very old and unupdated machine. What are the odds of my flash drive being infected with malware that can compromise the installation if i disable Secure Boot? What should I do in this situation? Can anyone shine me some light? Any help would be appreciated, thanks!

I have installed Linux Mint 22 in a DELL laptop with a buggy ACPI implementation (the kernel complains about it during boot). The laptop hangs if it goes to sleep (I tried various Linux distros/kernel-versions, the result is the same).

Because of that, I have disabled SLEEP in the firmware (latest version for that laptop btw). So basically, when you close the lid, nothing happens (it just locks the screen).

However, sometimes you might be in a hurry and you close the lid to do something else, and then you forget about it. The result would be for the battery to run dry, which eventually destroys the battery.

My question is: what would be the best way to setup an audible alarm if the battery reaches 20%?

Hi,

I would like to display the new lines of /var/log/messages that contain either IN_MyText or OUT_MyText (no matter where in the line)

I've tried

tail -fn 3 /var/log/messages | grep --color --line-buffered -e "(IN|OUT)_MyText"

But the output stay blank, when it should not...

Any ideas ?

I installed pop!_os as my daily driver some months ago (completely got rid of windows) and have thought it pretty good. But something about it seemed off - it would take programs just too long to open, it wasn't snappy... Once I got into something it seemed to run fine (playing dota or something else was fine after initial quirks).

Well, today, figured it out...

When I did the first install, I was very nervous about deleting all of my existing data on my disks and so tried to manually partition everything so that I could get it right (I think I was also planning to dual-boot).

Fast forward to today, and I'm testing speeds on all the drives to see which one to pitch for a new one I acquired. I see the 3 HDDs, but where is the SSD... Oh god, I installed the boot partition and root and home all onto one of the ~12 year old HDDs and the SSD has been sitting idle.

Anyway, just about done with the new fresh install onto the SSD, hopefully it isn't too hard to start port over the home directory from that HDD...

Recently I started experimenting with Owncloud Infinite Scale to see how it compares to Nextcloud (which is ostensibly slow).

OCIS is super fast! But, it feels very lackluster. For example, their android app does not support custom directory uploads. Their Linux desktop application is very bare-bones, and does not look good on GNOME.

I personally would love some plugins, but I cannot find anything on the internet about any being developed for OCIS, even though from what it seems it should be immeasurably better than developing a nextcloud plugin.

Does anyone know of any good OCIS Plugins, or is the community effort pretty much non-existent?

Has anyone here had success with USB fingerprint scanners? I also found this Microsoft keyboard with fingerprint reader but I don't know if it works with linux.
