Free working system Linux is seeking to Home windows as its position mannequin, at the very least on this a technique: implementing its personal Blue Display of Dying (BSOD) to warn customers in instances of a kernel panic.
The BSOD—with the official identify “DRM Panic”—might be included within the working system for the primary time with Linux 6.10, prompting customers to reboot. Its usefulness might be additional expanded within the close to future.
The entire thing was solved by direct rendering supervisor drivers (DRM drivers) and kernel mode setting drivers (KMS drivers). In Linux 6.10, the brand new DRM panic handler might be built-in into the kernel for the primary time. At launch, DRM & KMS drivers SimpleDRM, MGAG200, IMX, and AST are supported, with extra to comply with.
Nouveau-DRM panic patches are already in preparation, however will in all probability solely be built-in in Linux 6.11 as they gained’t be prepared in time for Linux 6.10. Systemd already launched an identical error display screen as a BSOD for its model 255 in December 2023.
What the Linux blue display screen seems to be like
Crimson Hat developer Javier Martinez Canillas confirmed a primary screenshot of the BSOD for Linux on Mastodon. Lo and behold, the blue display screen for Linux is way much less cryptic than Microsoft’s well-known BSOD.
You’ll see a totally blue display screen with an ASCII artwork penguin within the prime left nook. Within the heart of the display screen is the textual content “Kernel Panic!” with a smaller assertion beneath it, prompting the person to reboot the pc.

You’ll be able to take a look at the BSOD for your self
For those who’re on a system operating Linux 6.10 or greater—or one other system that already helps “DRM Panic”—then you possibly can manually take a look at the brand new Linux BSOD with the next command:
