¹ just in time for HDMI 2.2 to be ready and for the exact same problem to start again?

Fixed the annoying “no signal” issue on my external HDMI monitor after updating Ubuntu 24.04 on my ThinkPad P53 with an NVIDIA T1000 GPU.
This problem has happened to me multiple times after system updates, and every time I had to dig around for the solution again. Finally decided to document the fix properly for future reference.
If your Ubuntu updates suddenly break external monitor support, this guide might save you some time and frustration.

Pi Slate – A Raspberry Pi 5 handheld Linux cyberdeck with a 5-inch 1280×720 touchscreen display

We previously wrote about Carbon’s CyberT, a Blackberry-style Raspberry Pi CM4 handheld Linux cyberdeck designed for Kali Linux and penetration testing. The company, now operating under the CyberArch/Carbon Computers brand, has introduced the Pi Slate, a more powerful handheld cyberdeck designed for portable computing and security-focused applications. Built around the Raspberry Pi 5, the Pi Slate integrates a 5-inch 1280×720 touchscreen, a backlit RGB keyboard with an integrated cursor, and a 10,000 mAh battery for 3–5 hours of portable use in a compact enclosure. It supports modular expansion for HATs such as LoRa, SDR, AI accelerators, and M.2 storage, and includes cooling support, antenna mounts, and an optional modular back with a kickstand. It targets penetration testers, IT professionals, and field technicians needing a compact, preconfigured system for cybersecurity and field work. Pi Slate specifications: SBC – Raspberry Pi 5 with 2GB, 4GB, 8GB, or 16GB LPDDR4X RAM options Storage
