Thank you for that info. |

What kind of integrated VGA? |

( example Intel i915, i965, etc. ) |

The reason I ask is that the EFI framebuffer you have enabled should be |
20 |
built into a specific video driver. |
21 |
My system has an "amdgpu" video card. |
22 |
The EFI framebuffer driver for the console is enabled. |
23 |
The specific video driver called "amdgpu" is also enabled. |
24 |
The EFI framebuffer is built as a sub-component of the specific video |
25 |
driver "amdgpu". |

If you haven't already run this command, please do so : lspci | grep -i VGA |
35 |
. |

If the video device is a 'Aspeed ASTxxxx', the version number of the |
37 |
kernel you are using makes a big difference. |
