Or it could be the framebuffer compression or other power saving things. Since the last relevant kernel message is:
[180893.945295] [drm] Reducing the compressed framebuffer size. This may lead to less power savings than a non-reduced-size. Try to increase stolen memory size if available in BIOS. Does TLP tweak anything in that area? And does the bug occur without TLP? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1844934 Title: screen jitter after long idle To manage notifications about this bug go to: https://bugs.launchpad.net/oem-priority/+bug/1844934/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
