Applying the patch mentioned here solves the issue. https://bugs.archlinux.org/task/61964 Not sure if anyone's looking at this, but what about adding something to the kernel to allow a parameter to force the slow and wide eDP configuration on machines with this issue? Same issue for me, both lts kernel and 4.20.13 works fine. Have same issue too (In reply to Mark Weiman from comment #1) > Applying the patch mentioned here solves the issue. > > https://bugs.archlinux.org/task/61964 I confirm that applying the patch solves the issue. But since the patch mentioned seems to ignore the result of intel_dp_is_edp call... maybe a better solution can be found. The patch restores old behavior from 4.20 and before. I don't like the patch as is myself, but it does solve this problem. I am thinking of writing up a patch that changes this behavior to a parameter that can be passed on boot.

I totally agree with you: the patch solves the issue but I don't like the patch at all. I hope that someone with a better understanding of the problematic function can solve it in a better way since I am not able to. Created attachment 281889 [details]
patch
Here is an untested patch that allows this to be fixed with a kernel parameter.
Apparently, this is not the right place to open a bug for i915. |
Created attachment 281815 [details] kernel log On Arch Linux, when upgrading to 5.0 from 4.20, when the machine boots, the computer starts normally until a certain point where the screen goes black and never reappears. I've tried setting nomodeset with no success. Attached is a kernel log where loglevel=6 and drm.debug=6 are set.
