Disclaimer: "This tutorial only focuses on the second way to install Nvidia's proprietary drivers, if the "apt install nvidia-driver" way does not work on your installation, you can rely on this tutorial.To all those who use Plymouth with various scripts, there is a high risk of startup problems because Plymouth behaves badly with nvidia's proprietary drivers, so please do not follow this How-to. You can, however, find out more on the Plymouth Debian Wiki."

Prerequisites:

- make a backup with Timeshift (safety first)

- check graphics card compatibility
  (if your graphics card does not appear in the list, it is not necessary to install the latest driver, the one installed by default will suffice)

- command line as root to check which GPU is installed:
 

lshw -numeric -C display

Output

If the prerequisites are satisfied, you can continue with the tutorial below.

First step add non-free-firmware sources befor install Linux Headers and compilation dependencies:

nano /etc/apt/sources.list

Add the lines below behind each debian source and enabling the backports:

non-free-firmware

deb http://deb.devuan.org/merged daedalus-backports main non-free-firmware

Then update and install Linux Headers and compilation dependencies:

apt update && apt install linux-headers-$(uname -r) build-essential libglvnd-dev pkg-config dkms -y

Second step blacklist the nouveau driver, create a blacklist file:

nano /etc/modprobe.d/blacklist-nouveau.conf

In the file add the following lines and save the file:

blacklist nouveau
options nouveau modeset=0

Then regenerate the kernel initramfs:

update-initramfs -u

Third step install the latests NvidiaGraphicsDrivers:

apt install -t daedalus-backports firmware-misc-nonfree nvidia-kernel-dkms nvidia-driver nvidia-cuda-toolkit nvidia-cuda-dev nvidia-settings nvidia-smi nvidia-xconfig nvidia-opencl-icd nvidia-opencl-common nvidia-detect -y

Reboot.

To view how version you have installed, just open an terminal and enter follow:

nvidia-smi

Enjoy!

After a long time on Linux Mint Debian Edition, I come back to Devuan.

Before proposing my new HowTo, I wish you lots of good things for this new year 2025.

This HowTo based on the OpenRGB Wiki/Gitlab and other sources allows you to bring up all the RGB components of your computer, whether you are on an AMD or Intel chipset.

I. Installation, configuration and activation of I2C modules.

First step we need to dowload the I2C-Tools, open an terminal in Root:

apt install i2c-tools - y

Second step load the i2c module for AMD chipset:

modprobe i2c-dev

Add the user to the i2c group:

usermod $USER -aG i2c

Third step edit and load the i2c driver for your AMD chipset:

nano /etc/modules-load.d/i2c.conf

Add the line below to the file:

i2c-piix4

Load the i2c-piix4 module:

modprobe i2c-piix4

Now all necessary modules and driver are loaded.

II. Patching the kernel & UDEV rules.

Advice:Do not patch the kernel if you don't have a Gigabyte/Aorus motherboard.

Some Gigabyte/Aorus motherboards have an ACPI conflict with the SMBus controller, being on a Gigabyte motherboard I am impacted by this conflict.

First step edit the grub:

nano /etc/default/grub

Add the line below to your grub file:

GRUB_CMDLINE_LINUX="acpi_enforce_resources=lax"

To load the added command line we have to reload the grub and re-generate the grub.cfg file:

grub-mkconfig -o /boot/grub/grub.cfg

Second step download and install the UDEV rules:

wget https://gitlab.com/CalcProgrammer1/OpenRGB/-/raw/ca3c2ad54188c604c7626136ceda574e9fde3bc0/60-openrgb.rules?inline=false

Copy the file to the UDEV rules folder:

cp -R 60-openrgb.rules /etc/udev/rules.d/

If you installed openRGB before configuring for chipset support, you will get an error message telling you that there can only be one configuration file in the UDEV rules.

For this we need to remove one UDEV rules file at the location below:

cd /usr/lib/udev/rules.d

rm -R 60-openrgb.rules

Third step reload the UDEV rules && reboot:

sudo udevadm control --reload-rules && sudo udevadm trigger

reboot

At this point you can install OpenRGB, the application once launched will show all your RGB components.

Enjoy!

The well-known ufw firewall GUI is not available by default on devuan 5, so we will download the package from the Devuan Package View site:

wget http://deb.devuan.org/merged/pool/DEBIAN/main/g/gui-ufw/gufw_20.04.1-4_all.deb

To install the package:

sudo gdebi gufw_20.04.1-4_all.deb

And here is the firewall with a graphical interface.

When installing virtualbox via .deb file retrieved from the site, an error appeared because a dependency was not satisfactory for the installation. (libvpx6)

For this we will download the missing dependency and install it using the devuan Package View site:

wget http://deb.devuan.org/merged/pool/DEBIAN/main/libv/libvpx/libvpx6_1.9.0-1_amd64.deb

Once downloaded, just open an terminal window:

sudo gdebi libvpx6_1.9.0-1_amd64.deb

After installing the missing dependency you can continue installing virtualbox.

First step install Linux Headers and compilation dependencies:

sudo apt install linux-headers-$(uname -r) build-essential libglvnd-dev pkg-config dkms -y

Second step blacklist the nouveau driver, create a blacklist file:

sudo nano /etc/modprobe.d/blacklist-nouveau.conf

In the file add the following and save the file:

blacklist nouveau
options nouveau modeset=0

Then regenerate the kernel initramfs:

sudo update-initramfs -u

Third step install the latests NvidiaGraphicsDrivers:

sudo apt install firmware-misc-nonfree nvidia-kernel-dkms nvidia-driver nvidia-cuda-toolkit nvidia-cuda-dev nvidia-settings nvidia-smi nvidia-xconfig nvidia-opencl-icd nvidia-opencl-common nvidia-detect -y

Reboot.

To view how version you have installed, just open an terminal and enter follow:

nvidia-smi

Source

[Edit] After updating the repos there was a dependency error with the nvidia-settings package in the backports sources, to fix this incident it was enough to remove the backports source command.

It may happen that the persistenced daemon does not activate and need i386 binaries to work, it will then have to be done manually with the commands below:

sudo dpkg --add-architecture i386

sudo apt update

sudo update-rc.d nvidia-persistenced defaults

sudo service nvidia-persistenced start

FFmpeg is a collection of open source software intended for processing audio or video streams. Source

Be sure that you have the last version of ffmpeg:

ffmpeg -version

You will see an output of your version, in my case i have the last stable version 4.1.6.

No output??? Whaaaat!!! Don't panic on the Titanic, we need just to install the package:

sudo apt update && sudo apt upgrade -y
sudo apt install ffmpeg -y

Go to the Videos folder and we create an file like this, necessary to concat later:

file '/path_to_my_file/part1.mp4'
file '//path_to_my_file/part2.mp4'
file '/=/path_to_my_file/part3.mp4'

then save the file with a name of your choice in .txt output, in my example merge.txt.

Now we can merge our vids, the per-file main options retained are:

-f input/output with the concat option
-i input file or url
-c codec or stream output with the copy option

 ffmpeg -f concat -safe 0 -i merge.txt -c copy my_vids.mp4

After a few moments you can see your new merged video.

Enjoy!
