description |
Steps:
1. Installed system.
2. Verify the screen in the P2 of installation.
Actual result:
Screen displays abnormally, please refer to the picture in attachment.
Expected result:
Display should be good in all stage. |
[Impact]
On the machine of Lenovo M715, there is an AMD GPU (1022:15dd rev ca), when it
switchs to amdgpufb, the screen displays abnormally, we tested with a couple monitors,
all of them can reproduce this issue.
[Fix]
Backported 3 patches from mainline kernel, all of them focus on the change of
disable_vga(). After applying these 3 patches, the issue disappears.
[Test Case]
boot the system, run glxgears, everything works well
[Regression Potential]
Very low, these patches come from upstream, and I have tested them on at least 6 different
lenovo machines and those machines have different AMD GPUs on them, all of them worked
as well as before. |
