    Phoronix: Linux's New DRM Panic "Blue Screen of Death" In Action

    After being talked about for years of DRM panic handling and coming with a "Blue Screen of Death" solution for DRM/KMS drivers, Linux 6.10 is introducing a new DRM panic handler infrastructure for being able to display a message when a panic occurs. This is especially important for those building a kernel without VT/FBCON support where otherwise viewing the kernel panic message isn't otherwise easily available...

    Why does it have to be blue? Don't copy Windows!

    I'd rather prefer black, with white text.

      The color blue does not belong to Windows and there is absolutely nothing wrong with copying familiar patterns anyway. It is done all the time.

        I agree. This bright blue color is harsh and unpleasant. I'd personally prefer it to be dark red or amber. Much nicer, less stress inducing colors.

          Maybe the colours are tunable by the distribution..?

            Make it like it was on Commodore Amiga, so black background and red text or green one

              My dude, its a kernel panic screen. For those that ever see it, it should absolutely be stress inducing no matter the color.

                Red color would be more suitable for representing a panic.

                  Then add a scythe and a hammer.

                    It's one of the sixteen colors available in everything going back to CGA text mode in original 1981 IBM PCs fitted out for color (meaning it's a color that can remain consistent even on BIOS-based machines where you don't have a framebuffer driver and have to fire off the two or three x86 opcodes to ask the video card to modeset to 80x25x16color) and it's blue instead of intense or dim red or yellow/amber because Microsoft copied it off the MIPS firmware in one of the machines NT was being developed for at the time it was introduced.

                    (In other words, Microsoft's rationale, in PC Compatible terms, was "My Award/Phoenix/AMI BIOS setup screen uses a blue background with white text, so let's make this error message match that color scheme".)

                    In a sense, it's like tools like PartitionMagic 8 where your tech-illiterate family member insists their computer isn't failing to start Windows because they see a DOS tool's VGA mimickry of it with un-permission'd borrowing of Windows art assets, except it's pre-UEFI versions of windows being intentionally confusable with BIOS output.
