For the following error in the initial post: [ 421.603306] [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.
This can be solved by disabling framebuffer compression, which will have a pretty negligible impact on power management. @mvanross, I'm also working on a T480, so this may help you. To disable, edit /etc/default/grub (you need superuser privilege to do this) change: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.i915_enable_fbc=0" and run: sudo update-grub -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1866984 Title: linux-5.4 regression: hibernate-disk resumes instantly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/hibernate/+bug/1866984/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
