The only difference is when S2idle or S4 = hang the system will display this on the screen: [ OK ] Started Show Plymouth Boot Screen [ OK ] Started Forward Password R#s to Plymouth Directory Watch.plymouth-start.service [ OK ] Reached target Local Encrypted Volumes. systemd-journal-flush.service [ OK ] Finished Flush Journal to Persistent Storange [ OK ] Created slice Slice /system/systemd-backlight Starting Load/Save Screen #f backlight:intel_backlight... [ OK ] Finished Load/Save Screen # of backlight:intel_backlight. systemd-backlight@backlight:intel_backlight.service And it hangs, doesn't respond to any keypresses, it just sits there. So in short the only two changes are: 1) fixes S3 2) leave S2idle and S4 broken but displays a weird status on the screen on = hang So this is clearly affecting more than just S3, that timer has some purpose= in Amber Lake that breaks when the timer is shut down. --=20 You may reply to this email to add a comment.
