   @MagicLike Ah, it's not supported, sad.
   Mine doesn't have one, so no problems here.

   Though I did replace the normal cooler with the cooler of the Nvidia model to get lower temps :D

     @jana @MagicLike To be more specific: dGPU can work with specific Linux kernel versions but it was buggy as hell and thus disabled.

     If your T480 has Nvidia dGPU, note that the intel GPU is also still present; Libreboot configures that, exclusively.

     So, for Libreboot purposes, the Nvidia dGPU doesn't exist. On models that lack the dGPU, the same board is used but with an empty dGPU footprint. Might be useful for modboard adding 2nd nvme ssd!

     Info available there.

     @jana @MagicLike I'd be hesitant to support it, due to Libreboot's Binary Blob Reduction Policy:

     https://libreboot.org/news/policy.html

     Under this policy, it says: if a blob can be avoided, avoid it.

     It makes a special exception for dGPU ROMs though. Anyway, you need to extract a VGA ROM and insert it in flash, to use the dGPU. Also, relevant commit:

     https://browse.libreboot.org/lbmk.git/commit/?id=9dc3c86ae37db781b6bc4e745a57217c3511074b

     You could adapt a reverse of this diff, to handle the Nvidia ROM; kinda works with nouveau on linux 6.8 to 6.9, but very very buggy.

     @jana @MagicLike The irony is that initial versions of the T480 port didn't work properly with coreboot's native Intel graphics code either. It was quickly fixed; so quickly that I reverted the above patch adding Intel's VGA ROM, like within 1 hour.

     Anyway, if you're using SeaBIOS, you just insert that Nvidia ROM properly into CBFS.

     It probably won't work on FreeBSD - and I don't remember if it was tested under Linux with Nvidia's binary driver. Perhaps @mkukri can tell you more, he tested it.
