[Bug 1866984] Re: linux-5.4 regression: hibernate-disk resumes instantly
Hi I'm not sure if I can disable frambuffer compression (FBC). > cat /proc/cmdline says I disabled it: BOOT_IMAGE=/boot/vmlinuz-5.4.0-49-generic root=UUID=86dba13c-b77a- 4ac6-9f08-983354e5f8f1 ro quiet splash i915.i915_enable_fbc=0 vt.handoff=7 but > systool -v -m i915 |grep fbc says I did not: enable_fbc = "1" Does anyone understand this? -- 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

Dear Daniel, Thank you for that work-around! The error message is a bit odd, as it says that it may lead to LESS powersaving. Even then, once hibernated there is no power draw anyway -- 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
[Bug 1866984] Re: linux-5.4 regression: hibernate-disk resumes instantly
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
