First install pam_kwallet:

sudo zypper in pam_kwallet

Then edit the files /etc/pam.d/passwd, /etc/pam.d/login and /etc/pam.d/sddm as follows, i.e. add the lines beginning with a - (the hyphens are valid PAM syntax to reduce log entries if these PAM modules should not exist) and ending with the ### comment:

/etc/pam.d/passwd :

VirGL for Linux KVM guests on Ubuntu Desktop

NOTE: Please don't ask for help here, it was a miracle that I got it to work at all. Seek answers in the usual places (yes, even Stackoverflow knows more than I do).

The question: How can I get 3d accelerated graphics for Linux guests in KVM without using PCI passthrough?

The short answer is: Use VirGL. The long answer is more complicated, because the VirGL project has had slow but steady progress towards actually working reliably, but the degree to which any given Linux distribution (or related driver project) is in sync has varied greatly over time. Even if it works right now, today, on your machine, it might not tomorrow. Note that even when it works, graphics performance is mediocre to downright painful.

Tested on Ubuntu Desktop 22.04.04 LTS with qemu-kvm, in an "Ubuntu on Xorg" session (not Wayland). Linux quests must have spice-vdagent installed (Ubuntu installs this by default). The hardware is a AMD 5600G d

This guide is to improve the KDE Plasma experience on X11. It particularly applies to those using the modesetting driver (mainly Intel graphics cards)

Install Xorg-git or Xlibre

This is a crucial step. XLibre and xorg-git contain the "TearFree" feature for modesetting, which is not available in the standard releases. If you use a driver other than modesetting, check that the TearFree option exists for your driver.

Installation depends on the distribution you use. On Arch Linux and derivatives:

Xorg-git:

#!/bin/bash

# Function to display usage information
usage() {
    echo "Usage: $0 /path/to/input.mp4 [ /path/to/output_directory ]"
    exit 1
}

# Check if at least one argument (input file) is provided
if [ $# -lt 1 ]; then

eXtreme Go Horse (XGH) Process

1. Ich denke, also ist es nicht XGH.
In XGH wird nicht gedacht, es wird das erste gemacht, was in den Sinn kommt. Es gibt auch keine zweite Option, die erste ist schneller.

2. Es gibt 3 Wege ein Problem zu lösen: den richtigen Weg, den falschen Weg und den XGH Weg, welcher exakt wie der falsche ist, aber schneller.
