I think the upstream i915 developers might be able to best help you, since the issue still exists in 5.7. I checked and this report looks to be the same problem:
https://gitlab.freedesktop.org/drm/intel/-/issues/347 I'd suggest trying to help the developers debug the problem there. Looks like intel_idle.max_cstate=4 might be a workaround, of course then you are back to higher power consumption. ** Bug watch added: gitlab.freedesktop.org/drm/intel/-/issues #347 https://gitlab.freedesktop.org/drm/intel/-/issues/347 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1872760 Title: i915 - after return from suspend display is flickering To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1872760/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
