This is a short appreciation/user experience story. Tl;Dr I'm enjoying my time on linux

I have been using Linux for a while (gnome for a year with an Intel UHD gpu, and KDE for a couple of months on a recent AMD gpu), and till now there was no brightness slider. Moreover, I have used the same display with windows for several years and there was no slider as well.

As far as I know (I looked up online some years ago, but this info is sometimes hard to find) my display supports DDC/CI but doesn't expose brightness (haven't actually tried).

For some reason, about a week ago a brightness slider appeared on KDE but it didn't do anything. Yesterday while updating some unrelated stuff I noticed the slider again and moved it for shit and giggles, and the brightness actually changed...

I have several questions... and I don't even know which piece of software is responsible for this... but thanks

I have been using Linux on and off for several years, often alongside windows, but I have entirely switched to it (almost, I still have a windows PC that I use once in a while) about 16 months ago. I have to say that Linux does take a lot more effort in getting some things to work, but when everything goes smoothly it's sooo good, and improves every month.

In the span of a year my desktop experience has only got better. But the shock was when I booted up an Ubuntu 16.04 cd I had lying around to fix grub on a dual boot machine and it was barely usable. Now instead it's almost "plug and play". Plus Nvidia cards are getting more and more usable with every update, explicit sync is almost merged, and prime works fine already.

There won't be a year of the Linux desktop anytime soon (there's still too much that needs improvement), but the next years will definitely be exciting.

P.s.: does any of you know why display brightness works now?

My main question is about /run/user/1000:

  • Should I avoid touching it?
  • Could I delete it?
  • Is there something wrong with it?

Background: I'm fairly new to Linux and just getting used to it.

I use fsearch to quickly find files (because my filenaming convention helps me to get nearly everything in mere seconds). Yesterday I decided to let it index from root and lower instead of just my home folder.

Then I got a lot of duplicate files. For example in subfolders relating to my mp3 player I even discovered my whole NextCloud 'drive' is there again: /run/user/1000/doc/by-app/org.strawberrymusicplayer.strawberry/51b78f5c/N

Searching: Looking for answers I read these, but couldnt make sense of it.

Puzzled:

  • Is this folder some RAM drive so my disk doesnt show anything strange? Because this folder doesnt even show up at the root level.
  • Are these even real? Because the size of it (aprox 370 GB) is even bigger then my disksize (screenshot).

Any tips about course of (in)action appreciated.

Hi, I've been having issues with my network adapter on Bazzite OS. Both WIFI and Bluetooth do not work, and the the utility nmcli device confirms this. I used lspci to find my network controller, which is a `MEDIATEK Corp. MT7922 802.11ax PCI Express Wireless Network Adapter. I'm unsure how to proceed further. Thanks.

There have been a implementation of Opencl in the Mesa driver for a year now, But, have any software start using it? I got no luck with both Davinci Resolve and F@H, and now I am curious.

I recently had to use windows for stuff and after a year of using Linux, it made me realise how janky windows is in comparison. Even on a top spec pc unminimized (or resized) windows flash white before their contents appear. Super-d to minimize/maximize doesn't bring all windows back up or in the same order. And these are greatly amplified when the computer isn't that powerful, so much so that you can see individual regions of some programs render one by one. In addition, moving the kde connect window sometimes made the screen stutter and flicker (???) and at some point my mouse stopped working (touchpad was fine), I tried reinstalling drivers and stuff but ultimately I had to reboot for it to work again.

Brings back memories of my laptop loudly booting up in the middle of the night for no apparent cause or reason and mouse cursor going invisible upon random boots that made me save a file in the middle of the desktop about how to fix it.

It's incredible how Linux is both free and a more stable experience, even as a nvidia+wayland user.

Hi guys!

I downloaded the Fedora Sway (SPIN) ISO, but when I try to simulate it in VirtualBox, nothing happens.

Does anyone have any tips on how to proceed in this case?

Any tip is welcome.

I have been using Linux for about 5 years and although I don't consider that I know much, I know enough to fix my own problems and that's usually enough for me.

Since Plasma 6 was announced I wanted to test something other than XFCE, Gnome or Plasma (or any DE) so I give it a try with ArcoLinuxD i3wm and is increible the amount of things I learn the 'hard way' because there was no GUI to do the things I want to do, or maybe I was too lazy to do it with the terminal since there is always the 'easy way'.

Things that might be very easy for a lot of people, but I never take the time to learn, like mounting drives, running programs from startup, setting environment variables, creating desktop entries, and a lot of other things I didn't even remember. I even learned to use things that used to give me a headache just looking at it, like Vim, xdg, the Archwiki (that is super useful) and the manpages.

It's ironic because something that started as an experiment is now my daily drive, and now that Plasma 6 has been released, I don't want to leave i3 behind.

I believe this may be a niche question but hopefully someone may have an answer.

Has anyone gotten PipeMax working on Linux? Or does anyone know of a Linux native alternative software for automotive engine design? I'd rather not purchase a software for $100 only to not be able to get it working. I am not very knowledgeable on how to get Windows programs working on Linux as I've tried using Bottles and Lutris for Zwift but was unable to get it working.

Hi, I have an Asus vivobook pro 16x oled (M7600QC) optimus laptop with a dedicated Nvidia RTX 3050 Max-Q rated 50w. When I try to use the dedicated Nvidia GPU on Linux, the wattage is only 35w. If I enable the "nvidia-powerd" daemon, it goes up to ~40w. Is there a way to raise the wattage to the rated 50w like on Windows?

I've tried the following Nvidia drivers:

  • 550
  • 545
  • 535
  • 525

I've tried the following distributions:

  • *Ubuntu
  • Debian
  • Fedora
  • OpenSUSE Tumbleweed
  • Arch
  • ...

I use the laptop mainly for light gaming using Lutris with Wine-GE, 3D modelling and media consumption, thanks!

When I turn on my PC it gets stuck on bootloader, I can't do anything in it. As you can see on the image I don't have dual boot setup. I haven't changed any configuration recently. Any ideas what's the problem and how to fix it?

Solution: I put USB UEFI as first boot option in BIOS.

Hi all, I've installed Debian in 2 (mdadm RAID 1 formtted with Btrfs) NVMe drives installed into 2 PCIe adapters. The motherboard doesn't support booting from those drives, so I've installed Debian into a USB stick (and it works) and I wanted to add into grub the RAID NVMe drives.

os-prober doesn't see the other Debian installation. fdisk -l shows the 2 nvme drives, but it doesn't see md0:

I am on Manjaro GNOME 45.4 (x11) and after some recent update, I am unable to type for example: aa, or 77, or ANY two identical characters in a row, so it only registers the first: a, 7, etc.

If I press the right arrow key, I am able to type another (identical) character, after which I'd have to repeat it again and again if I want all consecutive characters: e.g. aaaa.

Note: this only happens at the login screen, not lock screen or anywhere else.

Is this on purpose? Some security feature? This has to be the dumbest security feature I can image, especially since it doesn't tell you that it's skipping the character (which is not obvious if you type fast), and it also does let you HAVE a password of identical consecutive characters.

I only found this forum post about it:

Hello everyone !

I have no idea if Iโ€™m in the right community, because itโ€™s a mix of hardware and some light code/command to extract the power consumption out of my old laptop. I need some assistance and if someone way more intelligent than me could check the code and give feedback :)

Important infos

  • 12 year old ASUS N76 laptop
  • Bare bone server running Debian 12
  • No battery (died long time ago)

Because I have no battery connected to my laptop It's impossible to use tools like lm-sensors, powerstat, powertop to output the wattage. But from the following ressource I can estimate the power based on the Energy.

time=1
declare T0=($(sudo cat /sys/class/powercap/*/energy_uj)); sleep $time; declare T1=($(sudo cat /sys/class/powercap/*/energy_uj))
for i in "${!T0[@]}"; do echo - | awk "{printf \"%.1f W\", $((${T1[i]}-${T0[i]})) / $time / 1e6 }" ; done

While It effectively outputs something, I'm not sure if I can rely on that to estimate the power consumption and if the code is actually correct? :/

Thanks :).

Edit:

My goal is to calculate the power drawn from my laptop without any electric appliance (maybe a worded my question/title wrong?). While It could be easily done with the top package or lm-sensors, this only work by measuring the battery discharge, which in my case is impossible because my laptop is directly connected to the outlet with his power cord (battery died years ago).

I dug a bit further through the web and found someone who asked the same question on superuser.com. While this gives a different reference point, nobody actually could answer the question.

This seems a bit harder than I though and is actually related to the /sys/class/powercap/*/energy_uj files and though someone could give me a bit more details on how this works and what the output actually shows.

This is also related to the power capping framework in the linux kernel? And as per the documentation this is representing the CPU packages current energy counter in micro joules.

So I came a bit closer in understanding how it works and what it does, even tough Iโ€™m still not sure what am I actually looking at :\ .

The robustness of Linux is widely acknowledged, but it canโ€™t quite match the microsecond management of a real-time operating system (RTOS) for time critical situations such as CNC machine instructions, vehicular control, or health sensor collection. If your software must record, manage, or control events within a narrow and precise time window and youโ€™re invested in Linux for core development, you can consider some of these strategies for handling time-critical tasks without abandoning your familiar environment.

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
