nvidia may allow backlight control after adding a registry flag to the configuration file.apple_bl works, but nv_backlight is preferred by gnome-settings-daemon. nv_backlight (nouveau) works in recent kernels.The kernel parameter "intel_iommu=off" fixes a broken wifi connection on kernel version since "5.10.0-15-amd64", due to a b43-phy0 kernel module error: "b43-phy0 ERROR: Fatal DMA error". This fix works for the default 5.10 kernel in Bullseye. After saving this change, be sure to run update-grub2 so that the changes are applied to /boot/grub/grub.cfg. Simply append the change to the end (with a preceeding space). Note that your system may have values other than 'quiet' and 'splash' in this list. GRUB_CMDLINE_LINUX_DEFAULT="quiet splash init_on_alloc=0 intel_iommu=off" The working solution is to disable this kernel option in the GRUB config: simply add "init_on_alloc=0" to the space-separated list of options in GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub: Mini Display Port connector works as of linux 3.2įix Suspending and Hibernating on BullseyeĪ kernel option enabled in recent kernels causes suspension and hibernation to become dysfunctional when using the open source nouveau driver (which is the only driver available for this hardware as of Bullseye).Mesa's nouveau_dri driver works, but with occasional rendering errors.Backlight control may require nvidiabl kernel modules to be built.

Requires setting PCIe registers to work around Apple's EFI firmware quirks.

Unsupported by the 5.10 kernel unavailable in Bullseye.

On Bullseye, a minor adjustment to GRUB's config is necessary to enable suspending and hibernating (see below).

The GPU is an NVAF integrated graphics core in the MCP89 chipset. Apparently adding the following to the kernel command line resolves this issue (unconfirmed): Occasionally only one out of the two cores is activated. Be aware partitioning utilities and grub on Linux may not identify APFS partitions properly.

If you want to update EFI firmware, upgrade to macOS High Sierra and repartition the APFS container to allow space for your Linux partitions afterwards as free space or as a HFS+ partition to be deleted during the Debian installer partitioning process. Runs on Bullseye installing in default EFI mode with latest Apple firmware.
