So this is a weird one, I’ll just say what I did then provide a list of symptoms. I updated the bios on my ‘Gigabyte B850 AORUS ELITE WIFI7’ motherboard from vF2 to VF12b; I did this by formatting a USB to FAT32, plugging it into the bios designated USB port, turning off the PC, waiting 30 seconds, then pressing the flash button and not touching it until it finished doing its thing and booted up of its own accord.

The results:

  • The card powers on.
  • The PC still posts and otherwise works, notable because my screen is plugged directly into the GPU.
  • ‘Linux Mint 22.3 - Cinnamon 64-bit’ system information can detect the GPU.
  • Other Linux Applets can not detect the GPU.
  • The motherboards BIOS somehow does not seem to detect the GPU.
  • No software, neither productivity applications nor games, can detect the GPU.

Solution
Disabling secure boot fixed it.

    It’s not uncommon that when a UEFI update is done that the settings will reset to default.

    I would see if legacy CSM mode is enabled. If the UEFI screen isn’t visible you will need to insert another GPU or use the onboard video if available.

    Does that board let you downgrade bios without a ton of fus?

    are you sure you have the right motherboard bios i don’t see vf12b on their support page the latest i see is F11a? since it happened after the bios update would suggest checking you have the right version and if you do, try downgrading to a known working version to rule out bios issues.

    I’ve seen on my msi board sometimes they post beta versions and take them down when i check for updates.

    Does your mobo have a hdmi input? Think its pretty standard from what ive seen. Also, what cpu? Does it have integrated graphics?

    I had similar issues swapping to linux mint. I wanna say it was something to do with Mint booting before gpu is able to fire up the gpu’s driver.

    Im honestly supper new to linux and i know ill get tar and feathered for saying it but i would be up shits creek if i wasnt able to get cli commands and scripts from claude.

    clear bios settings (power off and unplugged, momentarily short the jumper next to the cr2032 battery), pull card if you have integrated graphics on your cpu. if the system can boot back to bios–reset to defaults, do NOT enable xmp/expo yet. you may also need to disable secure boot for your os. once the system boots and shutdown ok, put the card back in and switch monitor over to it (and only it for now). then boot back up. see what drivers got loaded by the kernel for the video card.
