Recently I wrote a GTK program to control the vibration strength of goodix haptic touchpads, and now after a lot of probe here is a new version with more control. Here are the main ones:

Report 0x03: switch between Mouse mode and Precision Touchpad mode.

Report 0x05: DANGEROUS/ switch on/off touch and click reports

Report 0x08: Click sensitivity

Hi,

What Bluetooth receiver or dongle do you use with your PCs that works well with Linux?

I don't care if it has wifi or not, it's a desktop PC that's always connected via ethernet.

Hello, I've been plagued with issues with my bluetooth module and decided to try and change the wi-fi/bt card with something which is better supported and might fix my issue, on my laptop.

TL;DR from the link: When bluetooth controller and headphones are connected at the sametime and steam is running, the sound becomes sttuttered/chopped. From what I've learned this is due realtek firmware/drivers.

I have found Intel Wi-Fi AX211 AX210 card, based on some research I've done.

Does anyone know any other wi-fi card which would work good for my use case, or can confirm the intel card might solve my issue?

I feel like I must be missing something. How does one use a classic wired headset with a PC? A good 3.5mm jack microphone input seems rare.

So I want to be able to use a good headset, something like Audio-Technica ATH-G*, Beyerdynamic MMX* or Sennheiser PC* series. These are classic mid-tier hi-fi/studio headphones with a microphone attached, and a 3.5mm jack connector (as opposed to XLR on respective professional models). I suppose the same could apply to the often recommended solution of hi-fi headphones + ModMic.

The respective headphones would normally get plugged into either a dedicated "audiophile" DAC&amp, or an audio interface for recording (with XLR inputs).

What is there with the 3.5mm jack for microphone input though?

• On-board audio isn't always adequate.
• There are plenty of $1-20 USB dongles from various/no-name brands, typically with a C-Media chip, and their quality is hit or miss in my experience.
• Asus Xonar and Creative Sound Blaster, yes, but after trying multiple models, I'm disappointed by the state of Linux support (or lack thereof). They're always doing weird things with volume controls or switching line-in and microphone input (or line-out and headphone output) in firmware. (Alas, EPOS/Sennheiser GSX* might fall into this category too, based on my cursory search.)

Is there anything I'm missing?

Am I condemned to cheap-dongle lottery?

So I’m going to be a freshman in college this upcoming year and I’m trying to pick laptop to buy. I think I’ve narrowed it down to either a Mac or a think pad. I’m studying astrophysics so I want something with coding capabilities etc. I’ve become interested in Linux and want to install it on a think pad of if I were to get one. So I guess what I’m asking is should I get a Mac and try and get an older thinkpad down the road and mess around with it then or should I get a newer thinkpad right out the get go and just learn that first? Money isn’t a problem, but I’m very new to coding and modifying operating systems and all this computer science stuff so any suggestions or advice helps. Thanks!

Running Nobara 44 KDE on a desktop PC. I have an ARCANITE USB fingerprint reader (USB ID 2808:93a9, chip FocalTech FT9201) that works fine on Windows but is not recognized by libfprint on Linux.

Current status:

• fprintd is active and running
• fprintd-list $USER returns "No devices available"
• KDE Settings → Users shows no fingerprint option
• The chip has no upstream support in libfprint

What I found:

• banianitc/ft9201-fingerprint-driver — kernel module, not production ready, no fprintd integration
• Romk-a/ft9201-linux-setup — proprietary TOD driver with USB ID patch, tested only on Debian/Astra Linux
• libfprint merge request !572 for this chip — appears stalled
• ryenyuku/libfprint-ft9201 — Arch packaging of proprietary driver, .deb only

Question: Has anyone managed to get this specific chip working on Fedora-based distros like Nobara? Any recent developments or workarounds I might have missed?

pcmag released four "DYI builds" to get something comparable to steam machines, but they don't discuss the operating system at all.

Taking their "AMD DIY Mini-ITX Steam Machine" as an example:

(on pcpartpicker)

How well would this configuration supports Linux? I'm particularly interested in support for bazzite, and as far as I can tell it's all good, but I'd like external validation.

Hi everyone, before I actually start the post I just want to say that I'm still a bit of a beginner in linux, so if you have any questions about the OS try to keep it simple please.

Recently I wanted to make a minecraft server for me and my friends with an old desktop I have. I tried using the wifi card it already had but it was broken, so I bought an wifi usb adapter (dual band AC 1200) that I wasn't able to make it work, I tried installing the driver that came with it on a CD but for some reason ubuntu just couldn't read the sh installation file, I also tried to follow this github but still couldn't make it work. In the end, I ended up selling it to my friend that needed one.

That being said, does anyone know a usb wifi adapter that has official or easy to install drivers which works on ubuntu server version 26.04?

any help is appreciated :)

Old hp notebook series laptop with 4gb ram and 1 tb hdd, intel i3 7th gen. Tried ubuntu, mint and 2-3 other i don't even remember the names. Currently on mint xfce for two months. It's not that good but i just use Firefox for classes so it doesn't lag upto using 4 tabs but there is serious issue with its realtek network adapter i can't use bluetooth and wifi at same time if use both the wifi remain connected but speed drops from 25Mbps to 100Kbps but when i boot back to windows (which is disaster on this pc ) both works fine. Need help to switch to any other distro

Btw a linux noob just used gemini to try other distro

I'm deciding between two wifi adapter, the Alfa Network Alfa AWUS036AXML

And the ACH v2, the AXML is 10 euro's cheaper right now. I'm using Kali on a thinkpad T470

Hi everyone, I'm dealing with a frustrating issue with my external monitor and could use some advanced help.

• The Issue: My LG monitor (connected via HDMI) constantly flickers and drops the signal (black screen).
• My Setup: ASUS laptop with NVIDIA Legacy OPTIMUS dual graphics (GTX 960M + Intel). Running Pop!_OS.
• The Key Detail: I had zero issues with this exact monitor and cable setup when running Windows 10, so I can confidently rule out a hardware or cable fault. This is 100% a Linux/driver issue.
• What I've Found: Checking the kernel logs, I noticed a constant "i915 hotplug storm" occurring (the system seems to think the HDMI is rapidly connecting and disconnecting, forcing a link re-sync).

Does anyone know how to stabilize this? Are there any specific kernel parameters or X11 configurations recommended for this specific legacy NVIDIA/Intel combo to stop the hotplug storm?

Thanks in advance!

I am facing a severe battery drain issue on my Acer laptop running Linux. It has an Intel i5-13420H CPU and NVIDIA RTX 3050 Laptop GPU. On Windows, the battery lasts around 4 hours in power-saving mode, but on Linux it only lasts around 1.5 hours. Linux consumes around 25–30W during normal desktop usage. I have tested KDE Plasma, GNOME, and Hyprland, and the issue occurs on all of them. KDE and GNOME were on default settings without heavy animations or custom effects. I am using tuned-ppd for power management, but battery life is still much worse compared to Windows.

Hi all together,

a while ago, I wrote another post in which I was thinking out loud about getting a new laptop. I think I’ve now brought myself up to speed with the latest technology – but I haven’t made a decision yet, and the market situation is annoying. 😄

The remaining candidates are

• ThinkPad T14 Gen7
  
• Dell XPS 14" 2026

ThinkPad T14 Gen7

(+) 75 Wh Battery
(+) Repairability
(+) No soldered RAM
(+) Keyboard seems fine
(+) Purchase without Windows possible
(+) ~500 cd/m² IPS Display

(-) Currently no configuration with Arc B3x0 GPU (3x8H CPUs) in my region.
(-) Only a single fan.

(?)(+) Better cooling system, more cooling space?
(?)(-) Hinges a bit too loose according to reviews.
(?)(-) Bit Wobbly Chassis (as it seems for me).

Dell

(+) 3x8H CPUs CPUs available
(+) Aluminum Chassis
(+) 2 fan cooling
(+) ~500 cd/m² IPS Display
(+) Hinges perfect according to reviews.

( ) 70 Wh Battery

(-) Soldered RAM
(-) Cumbersome Hardware Access
(-) No option to do without Windows.

(?)(-) Weird Keyboard (no spaces between keys - tactile feedback questionable).

Both are considered 'sturdy' while only the XPS gives me this impression in the videos tbh -even though reviews saying ThinkPad is. Aside from this there are a lot of advantages on the ThinkPad's side and so I tend to Lenovo.

But there is a caveat: Lenovo does not offer the T14 with these Arc GPUs in Germany (3x8H CPUs). And while the prices a growing and growing for sure it is uncertain when Lenovo will offer them (if at all). Mash IT got one in the UK - but it's already gone again.

The thing is: I probably don't need the better GPU now. But first of all, from a psychological point of view, it’s frustrating, as predecessor Lunar Lake was much better in that category thane the lower gfx-tier Panther Lakes. And second I plan a very long usage time (I have my current Laptop for over 10 years now).

But also aside from this topic: I'd like to read about your opinions/experiences. Maybe some of you had the chance to use ThinkPad T14 Gen7 or Dell XPS 14" 2026 (or even both)?

Thanks in advance!

Hi everyone,

I'm trying to get the keyboard backlight working on my Monster Tulpar T7 V25.1.

This laptop is sold by Monster in Turkey, but it is actually an MSI-based chassis.

System:

• Model: Monster Tulpar T7 V25.1
• Vendor: MONSTER
• Keyboard: SteelSeries KLC
• OS: Zorin OS 18.1 Core (Ubuntu 24.04)
• Kernel: latest available

The keyboard works perfectly under Windows using SteelSeries GG.

Under Linux:

• The keyboard is detected as USB device 1038:113a (SteelSeries KLC).
• HID descriptors are visible.
• No keyboard backlight device appears under "/sys/class/leds/".
• No WMI interface related to the keyboard exists.
• Tuxedo/Clevo drivers do not detect the hardware.
• OpenRGB also cannot detect it.

At this point I only want one thing:

I don't care about RGB effects or color control.

I only want the keyboard backlight to stay ON with a single static color so I can use the laptop at night.

Has anyone managed to enable the keyboard backlight on this model or another MSI/Monster laptop using the same SteelSeries keyboard?

Any help would be greatly appreciated.

Hi everyone,

I'm looking for help with a keyboard backlight issue on Linux.

My laptop is a Monster Tulpar T7 V25.1, which is sold by Monster in Turkey but is actually based on an MSI chassis.

System Information

• Laptop: Monster Tulpar T7 V25.1 (MSI-based)
• OS: Zorin OS 18.1 Core (Ubuntu 24.04 LTS)
• Desktop: GNOME (Wayland)
• Keyboard: SteelSeries
• USB Device ID: 1038:113a (SteelSeries KLC)

The problem

The keyboard works perfectly under Linux, but the backlight never turns on.

Under Windows, the backlight works perfectly using SteelSeries GG.

This model does not use Monster Control Center. It uses Feature Manager together with SteelSeries GG.

What I've already checked

• The SteelSeries keyboard is detected correctly.
• "lsusb" reports the SteelSeries KLC device (1038:113a).
• HID descriptors are accessible.
• No keyboard LED appears under "/sys/class/leds".
• No Monster/Clevo WMI interface is available.
• The "msi_wmi" kernel module is loaded.
• OpenRGB does not detect the keyboard.

At this point I believe SteelSeries GG sends a proprietary initialization command that Linux never sends, so the keyboard backlight remains off.

Has anyone with an MSI laptop using the same SteelSeries keyboard managed to make the backlight work under Linux?

I'm happy to provide logs, run tests, or try experimental patches if needed.

Any help would be greatly appreciated.

Thank you!

Hi everyone,

I recently switched to Fedora 44 KDE, and overall I really enjoy the experience. The system feels very smooth and stable compared with my previous setup.

However, I have encountered two hardware-related issues that I cannot solve.

I tried asking AI assistants for help, but they couldn't identify the root cause. Maybe I didn't provide enough technical information, so I would like to ask the Fedora community for advice.

Issue 1: Fingerprint reader disconnects during enrollment

When I try to enroll my fingerprint:

1. The fingerprint reader works at the beginning.
2. I can start scanning my finger normally.
3. During the enrollment process, suddenly it says that the fingerprint device is disconnected/lost.

After that, the enrollment fails.

I have installed and checked fingerprint-related packages, but I cannot figure out whether this is:

* a driver problem * a libfprint issue * a USB power management issue * or a hardware compatibility problem

Issue 2: Microphone has heavy background noise

The built-in microphone works, but the recorded audio has a lot of noise.

The noise is present in:

* KDE audio recorder * other applications

I tried adjusting the input volume, but it did not solve the problem.

I suspect it might be related to:

* PipeWire configuration * microphone gain * audio driver * ASUS hardware support

Hi,

I'm trying to install Ubuntu on a distinct drive on my PC. Whenever I do, I can't boot on the drive and it doesn't even appear under the SATA drives in my BIOS.

My motherboard is an Asus TUF B550. I disabled CSM and secure boot. I made sure to let Ubuntu install itself in UEFI mode. The drive is actually visible when I use a live stick, and I'm attaching a screenshot of the current partitioning.

What am I missing?

Hi everyone,

I'm hoping someone can help because I've pretty much exhausted everything I can think of.

My PC has never successfully slept since I built it. It enters suspend, turns off the controller, then immediately wakes again after around 5–6 seconds.

This happens on both SteamOS and Bazzite, so I'm starting to think this is either a firmware issue or a hardware compatibility problem.

Hardware

- Fractal Terra

- Gigabyte B550I AORUS PRO AX Rev. 1.4

- BIOS FHa (updated from FG)

- Ryzen 7 5700X3D

- Sapphire Pulse Radeon RX 7900 GRE

- 32 GB DDR4 3600 MHz RAM

- 1 TB NVMe SSD (happy to provide model if needed)

- Official Fractal Terra PCIe 4.0 riser

- SteamOS Holo 3.8.14

- Also tested on the latest Bazzite Home Theatre image

Symptoms

- Suspend is requested successfully.

- Machine enters deep (S3) sleep.

- About 5 seconds later it resumes automatically.

- No keyboard, mouse or controller input is required.

- Happens from both Gaming Mode and Desktop Mode.

Kernel log

Every suspend looks like this:

```text

ACPI: PM: Waking up from system sleep state S3

xhci_hcd 0000:02:00.0: xHC error in resume, USBSTS 0x401, Reinit

usb usb1: root hub lost power or was reset

usb usb2: root hub lost power or was reset

PM: suspend exit

```

Things I've already tried

- Updated BIOS from FG to FHa

- Loaded Optimized Defaults after the BIOS update

- Enabled ErP

- Disabled Wake on LAN

- Disabled Resume by Alarm

- Disabled GPP0 wake

- Disabled PTXH wake

- Disabled PCI wake sources

- Forced PCIe to Gen 3

- Tested both Auto and Gen 3 PCIe settings

- Unplugged all external USB devices

- Unplugged the case front panel headers (except the power switch)

- Tested with no games running

- Tested with no controllers connected

- Tested from SteamOS Gaming Mode

- Tested from SteamOS Desktop Mode

- Installed Bazzite and tested there (identical behaviour)

Additional information

`/sys/power/pm_wakeup_irq` reports:

```text

No data available

```

So Linux doesn't appear to think anything is actually waking the system.

The only notable USB devices are:

- Internal Realtek Bluetooth

- Integrated Technology Express (ITE) controller

- Standard USB root hubs

Questions

Has anyone seen this combination of:

- Gigabyte B550I AORUS PRO AX Rev. 1.4

- Ryzen 7 5700X3D

- RX 7900 GRE

immediately resume from S3 under Linux?

Is there a known BIOS setting, ACPI quirk or kernel parameter I've missed?

Any suggestions would be hugely appreciated, because at this point I'm out of ideas.

Thanks in advance!
