Public bug reported: I have old MacBook with broken main Graphic Controller (a well-known hardware issue https://discussions.apple.com/thread/251049873 ).
So I switch to use Integrated Graphics Controller. I am using Ubuntu 18.04.6 LTS and after an 'apt update' laptop doesn't boot (freeze during boot). I looked for latest updated packages and I found: linux-image-4.15.0-192-generic 4.15.0-192.203 amd64 => linux-image-4.15.0-193-generic 4.15.0-193.204 amd64 So, MacBook boots linux-image-4.15.0-192-generic correctly, but it doesn't boot with newer kernels (4.15.0-193.204,4.15.0-194.205, 4.15.0-196.207) I could not find which change is included in newer kernels that did this issue. How could I support about this issue?
