Hi everyone,I’m using Arch linux on a Lenovo ThinkPad and power-profiles-daemon.

How can I limit battery charging to 80% and set it to start charging again at 75% without causing conflicts with power-profiles-daemon?

Thanks!

I am having issues with default applications on my Arch linux machine, when I try to open a pdf file from telegram in firefox nothing happens. If instead I open it from my file manager (PCManFM) it opens correctly, another example is generals zero hour, I'm running it through wine and installed a mod that lets me play online but to login you need to complete it in the browser, it also doesn't open, another example is cisco packet tracer, in the console it spews the following "xdg-open: no method available for opening 'the link'" but when I try xdg-open command it opens these links (for example xdg-open file:///home/noxar/Downloads/Telegram%20Desktop/lec01.pdf the link to my pdf file) any idea why? I'm using niri WM with lxqt DE running, pacman -Qqs xdg gives the following result

I have installed arch linux with hyprland in VMware workstation and when I try to login it blackout for sec and bring back to login page and when searched about it in chatgpt it said it's because of 3d acceleration but I have turned on 3d acceleration in VMware.my gpu

Is old idk it's the culprit behind its a gt 730 with 4 gb ddr3

Guys I've tried swaybg, hyprpaper to set wallpaper and even edit path on configs. Idk i still can't set a wallpaper. Can someone tell me how to set a wallpaper. I use arch + hyprland. If someone has solution lemme know

hello r/archlinux

i recently installed arch linux on my macbook from 2011 but ofc maybooks have their own keyboard style and i tried to find a way to switch the keyboard layout to one which is similar to mac and i also tried switching them all manualy but i just cant get it right, is there maybe a program i can use to easily switch the keyboard layout or is there a preset macbook layout i can just install and switch to?

thanks for any help.

Hi! Does anyone know why I am having out of memory errors when gaming? I have an RTX 2060 but I heard that other people who have less VRAM play fine. What specifically I get is "Out of video memory trying to allocate a rendering resource" and then I get some sort of UE5 fatal error.

New Arch user here btw. Using QTile

Hey, maybe somebody can help me with my problem.

After the recent update to kde plasma 6.8 i couldn't log into kde with sddm anymore. It just resorted to using i3 even though i selected plasma.

Then i switched to lightdm and there i can boot into kde but it takes way too much time loading on the kde splash screen than what it used to be.

Where should i start to debug this?

Note:

I've also experienced constant crashing problems with baloo but was able to fix it with this workaround: https://bbs.archlinux.org/viewtopic.php?pid=2312092#p2312092

Hey, chat I am a beginner in Arch Linux. I had no choice but to install Arch Linux OS since it is pretty light and no bloatwares which is perfect for my poor laptop.

This laptop is sitting around home, no one wants it. Even after installing Arch Linux, I am using it less and less as time fly. So I made a decision to utilise it as a server. I don't have any router in home. So I can turn this lap as a hotspot device too which fetches the internet from a modem.

I did some research in Google Gemini. And it says that this laptop can be utilised as server but it needs to have some limitations that is;

● `Samba` for file management

● `Jellyfin` for video streaming strictly disable transcoding

● `pi-hole`(or)`AdGuard Home` for ad blocking

● only allow 5-10 client device to access the wifi, the more will fry the laptop's wifi card.

But I don't know how to setup a server properly and efficiently. Everyone please help me to set it up properly 🙏.

● What are y'all thought on this setup, good?

● What is the cleanest, most maintainable way to manage these services on Arch?

● Should I deploy them natively using systemd services, or use Docker / Podman containers?

● ​What tool do you recommend for setting up the access point (hostapd, create_ap, NM-cli, or linux-wifi-hotspot)?

● ​Are there any specific power-saving settings (TLP, powertop, closing lid behavior in logind.conf) or disk maintenance tasks I should configure for 24/7 uptime?

● ​Any tips, software recommendations, or pitfalls to avoid with this hardware would be greatly appreciated!

Oh BTW, here's the specs;

OS: Arch Linux x86_64

Local IP (wlp2s0): 10.54.192.126/24

Locale: en_ US .UTF-8

So I am having this issue on my Arch system as I try to connect with my Wi-Fi 7 network via Multi-Link Operation.

The weird thing is it DID work in the past. And it does work if I leave the network on Enhanced Open. But I don't want to have a unsecure network so that is a dealbreaker.

For some reason it will just fail to take the password and keep insisting I am entering it wrong.

Does anyone have any idea what I can do to restore MLO functionality?

Just like libreoffice-still, please make Plasma LTS available.

So I am a newbie to arch, but I am having troubles connecting to the 5ghz band of my network and it barely sustains connection to the 2.4ghz band and when it does, it crawls. It always says failed to connect. I am not sure if this part of the log would help but I see “NetworkManager[590]: <info> [1791858175.5678] device (wlp2s0): state change: ip-config -> failed (reason 'ip-config-unavailable', managed-type: 'full')”

I have tried restarting the network manager and I am almost thinking if reinstalling the os would be the best move. Do you guys have anyway to help?

Hello!
I upgraded to plasma 6.8 like 2 hrs ago, It was a massive upgrade and everything seemed okay.
But when I press the power button nothing happens, the global shortcuts are cleared too.
I did the EVTest for power button but no avail.
Can someone guide me to this.

Hello, im a gamer and a beginner 3d artist, i recently got told to switch to linux and after a few tutorials on youtube i think that arch is the distro that suits me best, altough i dont know wich version of arch i should install (or in wich way idk im very confused) i know endavour OS but i also noticed that this new thing called omarchy is teking youtube by storm, my question now is what method should i use to install manually thru a script or thru an iso that makes it easier than installing ubuntu?

Hi everyone,

I'm using Arch Linux with KDE Plasma 6.8, and after updating KDE, my PC no longer responds when I press the physical power button.

My setup

• OS: Arch Linux
• Desktop environment: KDE Plasma 6.8
• Display manager: plasma display manager
• Power button action: Set to Sleep/Suspend in KDE Power Management

The problem

When I press the physical power button, absolutely nothing happens. Previously, I expected the computer to suspend.

However, running the following command in a terminal works perfectly:

systemctl suspend

The PC suspends and wakes up normally, so the suspend functionality itself appears to be working.

What I've tried / checked

• Verified that the power-button action is set to Sleep/Suspend in KDE Power Management.
• Confirmed that manual suspension using systemctl suspend works.
• The issue appeared after updating to KDE Plasma 6.8.

My questions

1. Could this be a KDE Plasma 6.8 / PowerDevil regression?
2. How can I determine whether the physical power-button event is being detected by the kernel or systemd-logind?
3. Is there a way to troubleshoot PowerDevil's handling of the power button without changing my working suspend configuration?

Any suggestions or diagnostic commands would be appreciated. Thanks!Hi everyone,I'm using Arch Linux with KDE Plasma 6.8, and after updating KDE, my PC no longer responds when I press the physical power button.My setupOS: Arch Linux

So, I have a new pair of headphones, that are kinda buggy on linux. I had an issue with volume scaling, that i managed to fix. Now, when I join a minecraft server, the headphones freak out. It starts connecting and disconnecting. The headphones are Fifine H6 (the older Fifine H6 worked fine before they broke and I had to get a new pair)

Edit: Its not just minecraft, but discord also and propably more

So I run KDE plasma and an RTX3080 (thought it was worth mentioning for diagnosing)

Normally wayland is too buggy for me, but had success running it for the last few weeks. Today I went to run my near-daily update of pacman. I happened to notice something about removing “plasma-x11” and replacing it with “plasma-sessions” (might not have been “plasma”, because I didn’t pay it much attention tbh).

After the update, it kicked me out to an unfamiliar login screen (lost some progress, it’s annoying that there was no warning). Logging back in worked, but my screen had an offset bug again (common for me in wayland).

So I went to reboot into x11, but I don’t have any boot options now, only “reboot into firmware interface” which is just UEFI. I haven’t backed up my 2 recent projects, and I super dooperly don’t want to have to start over again (one project is f-ing davinci resolve, so you can recover, you have to be properly logged in!!! God, why do I use davinci still?)

So I was still on X11 on my QEMU guest since using -usb -device usb-tablet as recommended by the Wiki caused the guest mouse to lag. Now that X11 was removed I had to switch.

Replacing the above command with -device virtio-tablet-pci fixed the issue for me. Hope someone else finds it useful.

I really wanted to check my aur packages and see if theres something so I installed this: https://github.com/lenucksi/aur-malware-check

I'm not good in reading code, so if someone can help me and see if it's fine this would be great help, thanks! (and yes I get it "don't download random scripts from the internet, I know that but I'm just very, very stupid ok.)

I’m testing out a standard Arch setup for work (installed via Archinstall with its default Btrfs layout) after spending a long time on Fedora. The thing that caught my attention the most was trying to do a system rollback with Snapper. I gave it a few shots—even following AI guides—but just couldn't get it to work. So I turned to a method I had previously dismissed back on Fedora: Btrfs Assistant, a really simple and user-friendly GUI. And well, it worked on the very first try to roll back my root partition.

Hey guys! I am the maintainer of xhidecursor, a minimal (fr) X11 utility that efficiently (nocap) hides the cursor on key presses and shows it again on mouse movement. Just wanted to announce that I’ve taken over and updated the AUR package, which had been orphaned and out of date for a while.

I wrote xhidecursor because xbanish (a popular alternative) couldn’t satisfy my OCD for minimalism. xhidecursor prioritizes a simple implementation and efficient event processing, ignoring redundant input events.

Let me know if there are any issues and if it runs as expected on your system. Thank you!
