Fn keys, reaction to lid close and reporting of battery state start working OK after suspend-to-ram and waking up the system. So, as a temporary workaround, I added 2-second suspend operation to run at each boot, as suggested here: https://forums.lenovo.com/topic/findpost/27/5027791/5148559:
/etc/crontab: ---------- <...> @reboot root rtcwake -m mem -s 2 ---------- Ugly, but it works for me. ---------------------------------------------------------------- As alternative workaround, it was suggested to use a custom ACPI DSDT table: https://github.com/masksshow/Thinkpad-E14-15-AMD-Gen-2-FIX. Looks like the script from that github repo does the following: * Dumps ACPI DSDT table and decodes it * Replaces "Name (H8DR, 0x00)" with "Name (H8DR, One)" there * Encodes the corrected table * Instructs GRUB to use it at boot. I haven't tried that. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1912946 Title: [ThinkPad E14 Gen2] Closing the lid does not trigger system suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1912946/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
