Michael Mikowski <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #5 from Michael Mikowski <[email protected]> --- I can confirm this is a kernel bug, and not an issue with KDE. Kubuntu has been tracking this issue for a few weeks, and it's almost certainly Intel i915 related on low-power Intel CPUs. Besides rolling back the kernel, it is highly likely that tweaking the more aggressive power saving parameters in i915. In particular, Key i915.enable_fbc=1 (framebuffer compression), i915.enable_psr=2 (panel self-refresh), and i915.enable_dc=2 (display C-states) to reduce idle power draw. Also see i915.mitigations. psr and fbc are the place to start. >From KF-6632: There was some concern about display stability noted in [reddit](https://www.reddit.com/r/Kubuntu/comments/1v7yf72/) and [this bug](https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2161881). However, because we do not have low power CPU variants, it does not appear that any of our systems have been effected. I suggest closing this bug here. -- You are receiving this mail because: You are watching all bug changes.
