启用吃灰的老机 MacBook Pro 2015 + eGPU(nvidia)
MacBook Pro 2015 上 XUbuntu 24.04 启用 eGPU (GeForce GTX 1080 Ti) 和核显 (iGPU + dGPU)，需解决黑屏问题
启动使用了 rEFInd 和 apple_set_os.efi: https://github.com/0xbb/apple_set_os.efi/
#refind install:
http://www.rodsbooks.com/refind/installing.html#packagefile
$ sudo apt-add-repository ppa:rodsmith/refind
$ sudo apt-get update
$ sudo apt-get install refind
apple_set_os.efi install : https://github.com/0xbb/apple_set_os.efi/
$ sudo apt-get install gnu-efi
$ git clone https://github.com/0xbb/apple_set_os.efi
$ cd apple_set_os.efi
$ make
配置apple_set_os.efi
$ sudo mkdir /boot/efi/EFI/custom
$ sudo cp apple_set_os.efi /boot/efi/EFI/custom
/etc/default/grub配置:
如下grub配置成功点亮内屏和外屏
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=realloc pci=nocrs apple_set_os acpi_osi=\"Darwin\" intel_iommu=off i915.modeset=1 i915.enable_guc=2 acpi_backlight=vendor"
$ sudo nano /etc/default/grub
修改 GRUB_CMDLINE_LINUX_DEFAULT
$ sudo update-grub
xorg & intel
$ sudo apt install xserver-xorg-video-intel
nvidia
$ sudo apt install nvidia-utils-535 nvidia-driver-535 nvidia-compute-utils-535
nvidia cuda
$ sudo apt install nvidia-cuda-toolkit
reset xorg
$ sudo rm /etc/X11/xorg.conf
重启
$ sudo reboot
!!重要的一点：
启动时候 refind的菜单先启动以下apple_set_os，然后在继续正常启动 xubuntu
进入桌面系统
执行如下命令检查系统:
$ cat /proc/cmdline
$ lspci -v -s 0a:00.0 | grep "Memory at"
$ sudo modprobe nvidia
$ sudo modprobe nvidia_modeset
$ sudo modprobe nvidia_uvm
$ sudo modprobe nvidia_drm
$ nvidia-smi
$ lspci | grep -i "vga\|display"
$ grep "EE" /var/log/Xorg.0.log
输出:
