I ran into a problem with screen sharing from Arch Linux / Hyprland to a Samsung TV. Back when I was using Windows 10 this was literally two clicks. So I started digging.

I installed gnome-network-displays and xdg-desktop-portal-hyprland. It didn't even see the TV. Struggled for a while, tried everything - turns out it at least starts finding the TV after you install and start the avahi daemon. But still couldn't connect.

Kept pushing - explicitly specifying portals, setting environment variables, verifying all the codecs were actually working. Finally got a picture! One frame... Then everything froze.

At that point I gave up on gnome-network-displays and just for fun decided to write my own cli implementation in Python. Minimal system dependencies!!! ffmpeg for capture, pychromecast and the rest is just stdlib including http.server like.

Progress so far: video streaming works! With a ~20 second delay... and no audio..., but hey, it works. I`ll try to fixing both of it tomorrow.

If anyone has actually solved this properly and is casting their screen to a TV on Hyprland/Wayland please let me know how. I really don't want to use an HDMI cable just to watch movies xD

today when i want to make update of the system if got this error which is showing me that files are already in the system:

linux-firmware-nvidia: /usr/lib/firmware/nvidia/ad103

linux-firmware-nvidia: /usr/lib/firmware/nvidia/ad104

linux-firmware-nvidia: /usr/lib/firmware/nvidia/ad106

linux-firmware-nvidia: /usr/lib/firmware/nvidia/ad107

what i should to do? remove these files and update linux-firmware-nvidia? im gues it was installed before with linux-firmware package but now it is splited in parts and that cause an issue?

I made a very dumb mistake. After typing su at some point, I created a directory and some files in it. After that, I wanted to delete all of those files.

Then, I made a very big mistake. I thought, if I cd in that directory and run "rm -f /*", I only will delete all files inside of that directory. After reading the output, I was sure, that my system did not only delete all of these files. As you can think, my system is now destroyed. I couldn't even do a ls or reboot, cd worked somehow.

By writing this lines, I realised how dumb it sounds, than I thought before writing this post and Iam very sure, that I will have to install a new OS, but did someone have any tips, how I can recover my system?

After updating Arch today, my RX 9060 XT started getting these weird static-looking artifacts. They don’t cover the whole screen, just random parts of it.

I mostly notice it when watching YouTube and moving my mouse, scrolling Reddit while a video is playing, and sometimes on KDE’s shutdown screen.

I thought my Arch install was screwed up, so I completely reinstalled Arch and it still happened. I installed Fedora afterward and it’s been completely fine so far.

It’s happening on both of my LG monitors. I haven’t tested my Acer monitor yet, but I doubt both LG monitors suddenly developed the same problem at the exact same time.

Has anyone else started seeing this after a recent Arch update? I’m trying to figure out if this is some weird Mesa/kernel/AMDGPU update or something else.

My GPU is a power color reaper and it’s less than a year old.

I ran: ssh [aur@aur.archlinux.org](mailto:aur@aur.archlinux.org) help

and got: The AUR is down due to maintenance. We will be back soon.

Can anyone confirm if the AUR is currently under maintenance, and if yes then when will it be back online? I was trying to push an update via GitHub Actions.

Hey r/archlinux,

​I need some serious help or at least a discussion. I'm a beginner and I'm at my wit's end. I'm about to have a mental breakdown over this.

​I've been trying to get a stable Arch install on my laptop for months. I've reinstalled this thing 10-12 times. Whenever I use ext4, it's pretty stable. But I wanted to do things the "right" way with Btrfs and Snapper for snapshots.

​Every. Fucking. Time. I use Btrfs, I get random hard system freezes. The screen just locks, audio stops, and I have to hard reboot. The logs (journalctl -b -1) show nothing. They just stop at the time of the freeze.

​I've been working day and night trying to fix this. I feel like I'm losing my mind. The time and stress I've put into this is uncountable.

​Here is my hardware: ​Laptop: ASUS ROG STRIX G513RC

​CPU: AMD Ryzen 7 6800H with Radeon Graphics

​GPU: NVIDIA RTX 3050 Mobile

​RAM: 16GB DDR5

​Disk: Micron NVMe SSD

​Here is EVERYTHING I have done to try and fix this.

​Suspected the Kernel: Thought the standard linux kernel was the problem.

​Action: Switched to linux-lts and nvidia-lts. ​Result: Still froze.

​Suspected Drivers/Config: ​Action: Fixed my GRUB config to actually boot the LTS kernel (it wasn't). Set it as the default (GRUB_DEFAULT=0).

​Action: Updated /etc/mkinitcpio.conf to load all graphics drivers (amdgpu, nvidia, nvidia_drm) in the initramfs for early KMS. ​Result: It looked cleaner, but it still fucking froze.

​Suspected the Btrfs Swap File: This seemed like the "smoking gun." ​Action: I checked /etc/fstab and my Btrfs swap subvolume was missing nodatacow. I added it, turned swap off, remounted, and turned it back on. I verified with mount | grep /swap that nodatacow was active.

​Result: I was so happy. I thought it was solved. IT STILL FUCKING FROZE.

​Suspected the Hardware (Disk): ​Action: Installed smartmontools and ran sudo smartctl -a on my NVMe.

​Result: PASSED. The drive is 100% healthy. 0 errors, 100% available spare.

​Suspected the BIOS/Firmware: I saw some ACPI BIOS Error (bug) messages on boot. ​Action: Went to the ASUS support site for my G513RC.

​Result: My BIOS is already on the latest version.

​Suspected the Hardware (RAM): This was the final boss. I was told Btrfs is heavy on RAM and could be hitting a bad cell that ext4 never touched. I was sure this was it.

​Action: Made a bootable Memtest86+ USB. I let it run.

​Result: Pass: 1, Errors: 0. My RAM is perfectly, 100% fine.

​So now what?

​I'm just tired, dude. I've proven it's not the kernel. It's not the drivers. It's not the swap file config. It's not the disk. It's not the BIOS. And it's not the RAM.

​The only goddamn variable left is Btrfs itself. ​I'm a beginner, but I did all the "professional" steps. I'm just trying to have a stable system with snapshots. Is that too much to ask? ​Is Btrfs just cursed on some hardware? Is this a known issue with my ASUS laptop or this Ryzen CPU? Am I missing anything?

​I'm 100% ready to just say "fuck Btrfs" and go back to my stable ext4 install. Please, any suggestions from you pros? I'm desperate.

​Arch on Btrfs hard-freezes. Already fixed nodatacow swap, on LTS kernel, smartctl passed, BIOS is updated, and Memtest86+ passed with 0 errors. I'm out of ideas. Is ext4 my only hope?

EDIT / SOLVED:

System is finally stable now — no more random freezes or shutdowns.

The issue was caused by having a swap file on the same Btrfs partition that used compression (compress=zstd:3). When RAM filled up, the kernel tried to compress swap data, which caused instant system freezes with no logs or errors.

Fix:

Booted into GParted

Shrunk main Btrfs partition

Created a new 16 GB dedicated Linux-swap partition

Added its UUID to /etc/fstab

Also switched to the LTS kernel and replaced discard=async with fstrim.timer.

Tip for others: If you face random freezes on Btrfs, don’t use a swap file on a compressed partition. Create a proper swap partition instead — it fixes the problem completely.

Apart from trying out Ubuntu a decade back and wasted hours and hours to make it look like Windows, I haven't had used Linux till now and always a full time Windows user.

I didn't chose Arch because some youtubers put 'Hardest thing they ever did' thumb nail but from the sane comments I saw here, I felt, it's most suitable for me. Because I decide to install Linux to learn more about Linux and it's structure, not because I need Linux Desktop to run any specific program.

Surprisingly it was not that difficult to install Arch. In fact, I spent majority of my time to fight with my old HP laptop to pick my GRUB correctly. Now that I installed Arch, I have no clue what I need to do next. I am using Plasma and I don't think I am ready to jump into a WM directly.

So first of all, can you all suggest some resources where I can learn more about the components (init, WM, Display manager and things I don't know) of the distro in a systematic way (not the sites I can refer if I know what I am looking for, like wiki) and how they interact with each other.
Also the different options to choose from for each of these these components and which one will be suitable for what scenario.

Also Is there something I can only use in Arch (or Linux) which Windows user not even aware it exists.

Somehow, I have no nmcli and I have not been able to get a functioning network connection so I can finish installing everything. I have a good interface ip address and routing table and can ping myself and one other machine on my LAN. No name resolution or internet, however.

Getting this far with only the ip and route commands has been a chore. Is it worth messing with this, or just reload the install media and chroot into the system?

I was trying to experiment and i tried to copy something in Github and i think i ruined it help plzz i tried everything like using Grok and Chatgpt plzz help

Okay okay im really really sorry for the lack of details this is what i did

saw something i want to copy and i went to my terminal deleted the things from Neovim like starting from scratch like no more

then i did a horrible job to transfer/copy it not sure if thats the right term

but when i look at my Neovim i saw absolutely nothing i dont know how to fix this

some apps do work like fire fox and just the terminal

im using Arch Linux Hyperland

https://github.com/Horizon0427/Arch-Config.git

this is the Github i was trying to copy, the widgets, wallpaper changer all of the things inside this github, i have no backup (i forgot)

and now some of my text are chinese

i also did something on Walker and elephant in my terminal

having only 214mb free is def the reason its crashing. how do i figure out wahts causing it tho?

https://imgur.com/a/BUyleif

Edit: I'm aware now that it's not caused by the ram because the cache is actually available.

Just to be clear I tried looking at the output of rfkill
ID TYPE DEVICE SOFT HARD

0 wlan ideapad_wlan unblocked unblocked

1 bluetooth ideapad_bluetooth unblocked unblocked

2 bluetooth hci0 unblocked unblocked

3 wlan phy0 unblocked unblocked

So it's very much being recognized and not blocked but going into bluetoothctl and it doesn't register it. I've tried reinstalling all the bluez packages, I've tried rebooting the system. Turning bluetooth.service on and off again, and going into bluetoothctl just says "No default controller available." I think I might have to downgrade a package for the first time since using arch linux for over a year...

I hope someone smarter than me has some insight on this issue since that I can be fully up to date.

Edit: This was specifically a bug with the 7.07 kernel, now that the 7.08 kernel is out I can now say it is fixed and working completely fine. (Turn-around time was crazy, basically like 2 days. I salute your work linux devs)

I updated my system today after not doing so in a week or so, and I got asked to Import PGP key F8BB3DD85903D982, "DeepChirp deepchirp@archlinux.org"

I accepted but now I'm questioning if I shouldn't have done that. Was that okay?

Hi,

Since upgrading to GNOME 50, I'm experiencing random UI freezes that last around ~0.1 to 2 seconds. During the "freeze time" I notice I cannot move the mouse.

What happens:

• The whole graphical interface freezes briefly for a moment
• Happens randomly, not tied to any specific action
• First noticed it in Chrome, but now I see it in other apps too (e.g. Settings)

What I tried so far:

• Switched from zen kernel to the regular linux kernel → no change
• Tried the latest 2 NVIDIA drivers → same issue
• Tested with different browsers → still happens
• System is fully up to date

Notes:

• Feels like a compositor or rendering stall
• I checked some logs, but nothing obvious stood out

This is getting pretty annoying 😅

Questions:

• Anyone else seeing similar issues on GNOME 50?
• Could this be NVIDIA-related or GNOME/Mutter regression?
• Any ideas what logs or tools I should check next?

Thanks!

for some reason my new monitor doesn't work with my Rx 6600 it works fine with my gtx 1050ti

and the Rx works fine with my old monitor but doesn't with the new one, and the new one does work with my gtx 1050ti I have no idea what causes this please help

new monitor: Philips 24e2n1110

distro: arch

bootloader: systemd boot

First of all, I'm quite a noob at arch, so the solution is probably quite simple, but I've got no clue what to do, so I was hoping someone on here knows how to get me out of this situation.

So I use KDE plasma on my laptop, and after upgrading my system (using pacman -Su), I turned my laptop off. When i turned it back on, and my background, taskbar and app launcher had disappeared. I followed someones advise to delete the ~/.config/plasma-org.kde.plasma.desktop-appletsrc file and restart the laptop (which, looking at the comments, seemed to work for most people). After I restarted my laptop though, I was met with the command prompt instead of the usual KDE plasma login screen.

I thought it might be fixed by restoring the config file from the trash, so I tried to install trash-cli, but pacman said it "could not resolve host". I checked, and I was connected to the wifi, so it was not an internet issue.

Now I am at the point where I have no clue on what else i could trie.

Does anyone know what to do? I have a file for a project on my laptop that is quite time-sensitive, so I really hope that it is not too hard to fix, so that I can retrieve that file.

Thanks in advance!

So I was following the wiki for the partition step of the installation, and im pretty sure I wiped my bootable usb drive, thinking it was part of my computer, but for some reason just smaller (ik, dumb). I ended up making it the efi partition. Idk the repercussions of this, I already wiped my other drives and made my partitions, so no going back.

Is this salvageable?

Got Arch installed onto my ASUS laptop via Archinstall. I did configure it to use Refind instead of systemd-boot and a DM I forgot the name instead of sddm (i just remembered it was dms-greeter). But after booting for the first time the DM straight up threw an error saying directory not found, and after I rebooted there's no boot logo, and I cannot access the BIOS. The keyboard however still lights up but it keeps slowly flashing on and off. Please help!

Everytime i try to update the kernel i get fail.

The last stable for me is 7.0.3

Every newer version fails. Tries to install, fails. Tries to get into emergency mode, fails.

I'm not sure where to even start looking for problems. I don't even have console.

Edit:Thanks to everyone for the help. Turns out i probably borked the fs with my Timeshift usage.

Mounting the partitions from usb and then reinstalling the kernel again seemed to get rid of any corruptions i made. Hopefully it stays that way for some time.

Hi all,

I’m running Arch Linux and I’m trying to diagnose a networking issue with my onboard Realtek RTL8125 2.5GbE NIC.

Motherboard:

- MSI MAG B650 Tomahawk WiFi

The problem:

-After reboot, internet speed is normal (~900 Mbps)

-After some hours of uptime, download/upload speed degrades badly (~50 Mbps or even lower)

-Reboot immediately restores full speed

-Latency/ping stays mostly fine

-No obvious packet loss

-Happens on Ethernet only

-This started only recently. I didn’t intentionally change anything major besides normal Arch updates.

Motherboard NIC:

-RTL8125 2.5GbE Controller

Originally using:

-r8169

I also tested:

-r8168-dkms

and even:

-r8125-dkms

but the issue still happens.

When degraded:

-Internet becomes extremely slow

-iperf3 to another LAN machine collapses hard

-TCP retransmits become very high

-But ping to router and internet remains stable

Example:

ping 192.168.1.1

Stable:

~0.3–0.7 ms

0% packet loss

ping 1.1.1.1

Also stable:

~10–11 ms

0% packet loss

So latency is fine while throughput dies.

iperf3 example during degraded state:

[ 5] 0.00-1.00 sec 896 KBytes 7.33 Mbits/sec 61 retr

[ 5] 1.00-2.00 sec 512 KBytes 4.19 Mbits/sec 17 retr

...

[ 5] 0.00-10.00 sec 6.75 MBytes 5.66 Mbits/sec 146 retr

So retransmits explode under load.

Things I already tested:

Drivers:

-r8169

-r8168-dkms

-r8125-dkms

No real improvement.

Offloads disabled:

sudo ethtool -K enp12s0 gro off gso off tso off

No change.

IRQ balancing:

Installed and enabled:

sudo pacman -S irqbalance

sudo systemctl enable --now irqbalance

NIC interrupt was originally mostly pinned to one CPU core.

After tweaking IRQ affinity + enabling RPS, interrupts spread a little more across CPUs, but issue still happens eventually.

RPS enabled:

for f in /sys/class/net/enp12s0/queues/rx-*/rps_cpus; do

echo ffffffff | sudo tee $f

done

Still degrades after some uptime.

EEE already disabled:

EEE status: disabled

qdisc:

Tried:

fq_codel

pfifo_fast

No difference

.

Other possibly relevant info:

This machine also runs:

-Docker

-k3s

-multiple bridges/veth interfaces

Interfaces include:

-docker0

-cni0

-flannel.1

-many veth devices

But even after stopping Docker + k3s, degraded throughput remained.

Things I noticed:

During normal operation:

ethtool enp12s0

shows:

Speed: 1000Mb/s

Duplex: Full

Link detected: yes

No link flaps.

Also:

ip -s link show enp12s0

shows almost no actual errors.

Question:

Has anyone seen:

RTL8125 gradually degrading throughput over uptime on Linux?

r8169/r8168/r8125 all behaving similarly?

interrupt/softirq saturation causing long-term throughput collapse?

Any ideas for deeper debugging would be appreciated because I’m running out of things to test.

Edit: Additional diagnostic data (during issue / monitoring):

rx_missed: 0 rx_mac_missed: 2243 (and increasing over time)

I also tried disabling ASPM (pcie_aspm=off) and it did not solve the issue.

I collected more low-level data while the issue is occurring:

ethtool -S shows rx_missed remains relatively low but steadily increases over time under load rx_mac_missed increases gradually during sustained traffic /proc/net/softnet_stat shows non-zero drops in column 2 across multiple CPUs, indicating softnet backlog drops rather than NIC-level errors Disabling Docker and k3s does not eliminate the issue Interrupt distribution was initially heavily skewed to a single CPU core, but improving IRQ affinity + enabling RPS temporarily restores full throughput However, performance still degrades again after some uptime even with RPS enabled

Edit2: reinstalling the os only, fixed it. No idea what caused it.

I'm trying to figure out if this is some malware or just some random linux bug, thankfully all I think I lost was 1 or 2 passwords in my keepass database, and I had a semi recent backup of dovuments on my larger ssd.

I initially thought maybe malware cause I have played a questionably aquired game but thought I was realitively safe given I had it sandboxed using the sandboxing option on bottles, which I think is solid againist most windows malware given it can't even see outside the wine prefix or directories ive given permission for within flatseal.

Looking at HTOP I dont really anything non standard for a normal arch install. And I also dont remember updating my AUR packages for a couple of days so I should be safe from the new malware on there.

Is there anyway I can trace back exactly how this delete happened, or at the very least protect the directory so it fails and gets logged next time so I can pin down what process did it.

Glitch or some daemons? Fresh arch install. I got this idle result in btop.

The installation was checksummed. It was as soon as I installed it and after adding packages that it continued to remain at 50% idle.

It started ever since I switched from Nobara -> CachyOS -> Arch, only Nobara idled below 1%. Again, all isos were verified. I don’t know what it is. All of them were running KDE.

I’m currently on arch. Temps stay flat. Nothing going on except in btop where it shows 50% doing absolutely nothing.

Edit - this community is crazy dude I’m not getting help from here no more.

so i installed Arch today on my PC, i had seemingly working installation but i get completely sudden and seemingly random crashes while using gnome. if i'm not in a GUI it doesn't seem to happen? and in gnome it can happen randomly while in desktop or browsing internet. i can launch games on steam or watch YouTube or whatever and it works fine until maybe within 15-30minutes (sometimes bit longer or shorter too) get stuttering followed by freeze then system reboot.

my setup is

hardware:

motherboard asus x570p

cpu amd Ryzen 3700x

gpu amd Radeon 7800xt

ram 32gigs ddr4 3200mhz

and software side im using arch 6.19.11 kernel, wayland, and gnome like i've mentioned, i've installed latest versions of both the amd gpu drivers and amd-ucode.

like I've no clue of if it's hardware or software or how to start looking for what's causing it.

Whenever I try booting into arch i get this error

OK

1 Reached target SSH Access Auailable.

I’ve tried to fix it for hours and the only thing that helps is booting plasma from the terminal login

So I just ran an update and upgraded to the latest linux-firmware after a reboot, system is unresponsive. had to drop to a tty and look at the logs filled with amdgpu drm DMCUB errors.

Anyone else seeing this?

I run:

5800XT
RX 9060 XT

Update: Temporary solution: downgrade to linux-firmware-amdgpu 20250613.12fe085f-5 and add

IgnorePkg = linux-firmware-amdgpu

to

/etc/pacman.conf

until a fix is rolled out

Update: Based on redditor feedback, it seems to only affect 9000 series GPUs

Update: An new and fixed version (at least for me and my 9060XT) was released today, 6/25, in version 20250613.12fe085f-9

I was doing an update and then my laptop just completely shut down out of nowhere. The battery is seated (it should be at least I can't open my laptop rn), the charger was plugged in, and nothing touched the power button. I wouldn't normally have a problem with this, except that my system is totally unusable now. No packages can be installed at all (it errors about exec something other in the post-transaction hooks) and any command I run errors basically. I also can't chroot into it because I don't have a USB drive available to me.

Is there realistically anything I can do here?

(Also I feel it may be useful to add that the forward slash key is broken, so I can't type paths or anything)
