For some reason, when the swap partition UUID changes, Debian takes much longer time to boot due to swap partition UUID mismatch in both /etc/fstab and /etc/initramfs-tools/conf.d/resume. This can happen when swap partition gets reformatted and assigned with new UUID.

Here is how to fix it:

1. Get into root:

$ su
$ export PATH=/usr/sbin:/sbin:$PATH

Typical GRUB boot menu looks like the following:

|*Debian GNU/Linux            |
| Devuan GNU/Linux            |
| Other ...                   |

Description

In most older (maybe also newer?) DELL workstations and thin clients, for example: DELL Precision T5810 and DELL Wyse 3040, Debian is not able to boot after installation is completed. This is because your workstation expects to boot from /EFI/BOOT/BOOTX64.EFI and it cannot find it. There is a way to manually configure this in Setup page and point to the correct grubx64.efi location, but for some reason it keeps trying to load from /EFI/BOOT/BOOTX64.EFI. The workaround provided here is basically renaming the grubx64.efi into BOOTX64.EFI and put it exactly where your workstation is expecting it.

Installation Example on DELL Wyse 3040

Debian 12 Bookworm running on QEMU

Initially, it had qcow2 image size of 16GB, and this is how to double its size to 32GB:

host $  qemu-img resize diskimage.qcow2 +16G

Boot into Debian 12 and run fdisk with root privilege:

$ su

Ultimate Beginner's Guide to Proxmox GPU Passthrough

mirror of The Ultimate Beginner's Guide to GPU Passthrough (Proxmox, Windows 10) by /u/cjalas

>Welcome all, to the first installment of my Idiot Friendly tutorial series! I'll be guiding you through the process of configuring GPU Passthrough for your Proxmox Virtual Machine Guests. This guide is aimed at beginners to virtualization, particularly for Proxmox users. It is intended as an overall guide for passing through a GPU (or multiple GPUs) to your Virtual Machine(s). It is not intended as an all-exhaustive how-to guide; however, I will do my best to provide you with all the necessary resources and sources for the passthrough process, from start to finish. If something doesn't work properly, please check /r/Proxmox, /r/Homelab, /r/VFIO, or

Prerequisite

1. Soldering tools.
2. 4x Female header jumper wires.
3. 2x ST-Link v2 clone, one is used as a target and the other is used as a programmer.
4. This guide has only been tested on ST-Link v2 clone with STM32F103C8T6 mounted on it.
5. This guide was written and tested on macOS Sonoma. It should work on Linux, and also Windows under WSL/WSL2.
