Changing Nvidia card fan speed

In MSI Afterburner make own curve. Some video cards need checkbox "Override zero fan speed with hardware curve" in Fan settings. Fans will start at +60 and stop at +40, depending on video card.

In Linux Nvidia Settings uncheck Enable GPU Fan Settings.

watch -n 1 nvidia-smi

nvidia-settings -a "[gpu:0]/GPUFanControlState=0" // enable auto fan control

nvidia-settings -a "[gpu:0]/GPUFanControlState=1" // manual fan control

You can try nfancurve - https://github.com/nan0s7/nfancurve 

Switching to Nouveau (Open Source NVIDIA driver)

Discoder > Additional Drivers > Nouveau display driver

sudo reboot

BUT u will loose fan control and coolers will be spinning all time.

Asus H170 PRO GAMING BIOS is not displayed

Current BIOS: H170-PRO-GAMING-ASUS-3403

https://www.asus.com/supportonly/h170_pro_gaming/helpdesk_bios/

Problem: BIOS is not displayed, can’t enter BIOS, cursor/underscore on black screen.

Cause: unknown. PC stayed some time unused and then this… Power on PC and it shows black screen with non-blinking cursor, then monitor blinks and you get same black screen with non-blinking cursor. Tried on old and new TFT monitors with DP, HDMI, VGA, DVI-D – same. Tried on discrete video – same.

Potential cause: low CMOS KTS battery - 2.6 V - may have corrupted BIOS.

I can boot from USB WinPE without any problems and see hardware with utilities, if no OS is installed on any HDD or SSD.

Windows PE => CMD with admin rights => shutdown /r /fw /f /t 0 

I can boot from Win 10 USB and install Windows 10 on HDD or M.2 SSD, but after install Windows won’t boot. You get same black screen with non-blinking cursor.

I can’t enter BIOS by pressing F2 or Del, but Ctrl+Alt+Del reboots PC without problems.

When entering UEFI BIOS from Kubuntu USB GRUB menu PC turns off and then restarts.

I can’t flash BIOS with BUPDATER or AFUDOS.

With BUPDATER PC simply reboots or proposes to secure flash and reboots.

With AFUDOS I get message that BIOS is write protected. Can’t backup it and can’t flash it.

I changed battery, unplugged devices, removed CPU, tried another PSU, changed memory modules, reset CMOS many times but nothing helps. Looks like BIOS is working because with service utilities booted from USB drive I can see sensors, all specs, test video and cpu, hdd and ssd are visible, etc… But I can't enter BIOS.

BIOS chip flash solved the problem. Used buggy CH341A black USB 5V adapter, CH341-USB/CH341WDM.INF driver, UEFITool.exe, AsProgrammer_2.0.3a, Windows 7.

AFTER 3805 BIOS flash LAN Intel Ethernet Connection (2) I219-LM  stopped working!!!

Flashed 3403 BIOS again!

Install CH341A drivers and AsProgrammer_2.0.3a on Windows.

Install flashrom on Linux. [ You may also need libftdi1-2, libusb-0.1-4 ]

To convert an ASUS .CAP BIOS file into a .BIN file, follow one of these methods:

Method 1: Remove the CAP Header Manually (Hex Editor)

    Open the .CAP file in a hex editor (e.g., HxD or Hex Editor Neo).

    Look for the header size:

   ASUS BIOS .CAP files often have a 2 KB (0x800) or 4 KB (0x1000) header. Check the first few bytes — if it starts with "AMI", "ASUS", or similar markers, it’s part of the header.

    Delete the first 2 KB or 4 KB from the file.

    Save the modified file as .BIN and use it for flashing.

Method 2: Extract with UEFITool

    Download UEFITool (GitHub).

    Open the .CAP file in UEFITool.

    Right-click the BIOS region (usually labeled BIOS Region or UEFI Image).

    Select "Extract as is" and save it as a .BIN file. This removes unnecessary headers while preserving all firmware regions.

Method 3: Use AMI Firmware Update Tools

    Download AFUWIN or AFUDOS (AMI tools for BIOS modification).

    afuwin.exe /CAP_TO_BIN input.CAP output.BIN

    (Command may vary depending on your BIOS type.) This extracts the raw BIOS image.

After conversion, check that:

The .BIN file is slightly smaller than the .CAP file.

The structure is correct (compare it with an extracted .BIN from a working board).

It includes the necessary firmware regions (e.g., ME firmware for Intel chipsets).

These parameters allow to browse Windows LAN and network machines in Dolphin. To access shared folders on Windows PCs login and password are needed: Any Any. Problem with Windows 7 PC.

Actually only server min protocol = NT1 can be used, but in such case there will be no WORKGROUP icon in Dolphin and NO access to Windows 10 computers with SMB 1.0 activated BUT access to Windows 7 PC will be granted - therefore both client NT1 are necessary (for Windows 10 PCs with SMB 1.0). All Windows PCs and Android devices have access to shared folders on Kubuntu 22.10.

Linux users worldwide

Estimating the number of Linux/Unix users worldwide compared to other popular operating systems (OS) like Windows, macOS, Android, and iOS is challenging due to the diverse use cases (desktops, servers, mobile, embedded systems) and the lack of precise user tracking for open-source systems like Linux. Below, I provide an analysis based on available data up to June 2025, focusing on market share and user estimates across device types. I’ll break it down by desktops/laptops, mobile devices, servers, and supercomputers, then estimate total users relative to the global population.
