[Problem Description] After updating linux-firmware to version 20240318.git3b128b60-0ubuntu2.29, = the right half of the primary monitor turns completely black (it was vertical l= ines blue, green and black at some point too) upon booting into GNOME (Wayland).= =20 - Hardware failure ruled out: Live USB, BIOS, and software screenshots all render normally. - Software composition issue: The mouse cursor remains visible and moves fr= eely over the blacked-out region, indicating the hardware overlay plane receives signal, but the desktop framebuffer fails to render on that panel region. [Steps to Reproduce] 1. Boot Ubuntu 24.04 with linux-firmware version 20240318.git3b128b60-0ubuntu2.29. 2. Log into GNOME desktop session. 3. Observe half of the display panel dropping output to black. [Bypass / Confirmed Fix] Downgrading linux-firmware back to version 20240318.git3b128b60-0ubuntu2.27 immediately resolves the issue: 0. wget https://snapshot.ubuntu.com/ubuntu/20260801T000000Z/pool/main/l/linux-firmw= are/linux-firmware_20240318.git3b128b60-0ubuntu2.27_amd64.deb 1. Installed linux-firmware_20240318.git3b128b60-0ubuntu2.27_amd64.deb. 2. Ran `sudo update-initramfs -u` and rebooted. 3. Full screen rendering restored instantly.
