I had a suspicion with power-saving and disabled screen dim function, that solved this problem, but I have noticed, that the system froze also after wake up from sleep (suspend to RAM) and also when I plugged in external HDMI beamer. My hardware is lenovo X1. When looking at logs I found nothing suspicious: 2021-01-07T09:05:28.131783+01:00 brko-notebook chronyd[780]: Source 62.168.65.36 offline 2021-01-07T09:05:28.132198+01:00 brko-notebook chronyd[780]: Source 46.29.2.171 offline 2021-01-07T09:05:28.132419+01:00 brko-notebook chronyd[780]: Can't synchronise: no selectable sources 2021-01-07T09:05:28.136878+01:00 brko-notebook kded5[1557]: plasma-nm: Not emitting connection deactivated notification as we're about to suspend 2021-01-07T09:05:28.138183+01:00 brko-notebook systemd[1]: Reached target Sleep. 2021-01-07T09:05:28.142508+01:00 brko-notebook systemd[1]: Starting Suspend... 2021-01-07T09:05:28.185368+01:00 brko-notebook systemd-sleep[8439]: INFO: Skip running /usr/lib/systemd/system-sleep/grub2.sleep for suspend 2021-01-07T09:05:28.188613+01:00 brko-notebook systemd-sleep[8434]: Suspending system... 2021-01-07T09:05:28.188776+01:00 brko-notebook kernel: [ 1625.713697] PM: suspend entry (s2idle) 2021-01-07T09:10:41.253275+01:00 brko-notebook systemd[1]: Queued start job for default target Graphical Interface. 2021-01-07T09:10:41.253333+01:00 brko-notebook systemd[1]: systemd-journald.service: Succeeded. 2021-01-07T09:10:41.253358+01:00 brko-notebook haveged[477]: haveged: command socket is listening at fd 3 2021-01-07T09:10:41.253364+01:00 brko-notebook systemd[1]: Activated swap /dev/disk/by-uuid/a8fee06a-e4e4-477b-927e-ce7691143519. 2021-01-07T09:10:41.253368+01:00 brko-notebook systemd[1]: Mounted /.snapshots. -- You are receiving this mail because: You are on the CC list for the bug.
