I have seen that the behavior gets activated since 4.0-rc1 https://github.com/torvalds/linux/commit/b0dcaf4fbb36895175657be029ed64eda2a34707
I have downloaded Mainline 4.0-rc6 and testes but it did not work. Then I found out, that the author did not activated the behavior for all Samsung laptops. https://bugzilla.kernel.org/show_bug.cgi?id=75901 shows the commands to enable this behavior: cd /sys/kernel/debug/samsung-laptop/ echo 0x81 >d0 echo 0 >d1 echo 0 >d2 echo 0 >d3 echo 0x6e > command cat call Then I can close the lid and it goes sleep instantly. After lid open it wakes up from sleep. This has to be enabled by default for my laptop. ** Bug watch added: Linux Kernel Bug Tracker #75901 http://bugzilla.kernel.org/show_bug.cgi?id=75901 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1293134 Title: [Samsung 700Z3A-S02DE] Laptop does not resume from suspend upon lid open To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1293134/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
