Macbook pro 2011

You're still a human being :stuck_out_tongue_winking_eye:

Can you please post the terminal output of:

dmesg | grep -i amdgpu

Copy and paste... I understand that using the terminal is tricky with your display issue. I know of no easier way of using GUI method to get this information. Please be patient...
You also can post Screenshots.

Return nothing

hmm... So no error logs from booting the graphics card, then.

The drivers on this card were released in 2015. These really should be well integrated into the kernel...
Have you run any updates since installing?

sudo apt update && sudo apt full-upgrade

Did you install the Oibaf drivers that @Michel suggested?

I run the full upgrade. A lot of file downloaded and installed. Goes the Possible missing firmware /lib/firmware/i915/tgl_guc_49.0.1.bin for module i9
W: Possible missing firmware /lib/firmware/i915/dg1_dmc_ver2_02.bin for module i
message i got means enything?. I wander if the GPU in disable. I got this laptop from my daugther and she hed it servive- add memory to 16 Gig, It does have i7 slow 2G

This is probably harmless, just annoying. If you feel inspired to fix it:
(Edit: @Michel posted the link already)

Is this machine equipped with Intel and AMD radeon graphics?

When in Mint, I installed the vmplayer and win10. Win10 worked fine, but no graphic acceleration. Instakked win7 games and all worked fine,

Yes, If it is not disable then it beat the record working. Most of them burn out after 3-4 years and apple replace with the some board - junk

Is the any way to check if the gpu is disable?

I am using Windows 10 in VMWare on Zorin.
I do have 3D acceleration on Windows 10.

What I learn is that many people disable the gpu to use Intel graphic only

lsmod | grep radeon

You can also check if anything is blacklisted in /etc/modprobe.d/blacklist.conf

I wonder if you need to check mesa and Vulkan.

yface@myface-MacBookPro:~$ lsmod | grep radeon
radeon 1474560 18
drm_ttm_helper 16384 1 radeon
ttm 73728 2 radeon,drm_ttm_helper
i2c_algo_bit 16384 2 radeon,i915
drm_kms_helper 237568 2 radeon,i915
drm 548864 11 drm_kms_helper,radeon,drm_ttm_helper,i915,ttm

Any luck checking the blacklist?
What is tricky about both Intel and AMD drivers is that they both are included in the kernel.
While Intel is pretty good about this, AMD leaves something to be desired.

I cannot help but think we may chase our own tails pursuing drivers. Rather, we may need to modprobe the existing drivers in the kernel.

On Mint forum, they saying that I can not install Mint without disable the GPU on 2011 Macbook Pro. The give long line of codes. I did not disable GPU and Mint, Zorin boot and install. That is the reason for my suspicion that my GPU is disable.

I have Z16 core running on a machine just like yours but I've disabled the AMD GPU as it doesnt work anymore. Only using the integrated GPU from intel. I cant tell you how to disable it by GRUB, that's the way i did it, in case it might help you at least to check if you can mirror to an external monitor.

Thanks. What I have to do. If I disable the GPU will my external monitor work?. Someone said that the amd gpu controll the external monitor

this is possible if you have Two Ports on the computer and only one belongs to the Intel graphics and only one belongs to the radeon card.
