Hello to everyone,
Been using on and off Kubuntu for several months but completely unable to solve the following problem:
Whenever I suspend my laptop, it cashes (black screen, no mouse movement, all light i/o lights on) and restarts on itself after +-20 seconds.
Here is my config:
5.4.0-77-generic #86-Ubuntu SMP Thu Jun 17 02:35:03 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux
Tried to read through a post-crash syslog and stumbled across this: kernel: [ 10.075295] Lockdown: systemd-logind: hibernation is restricted; see man kernel_lockdown.7
Seems secure boot is preventing this? Tried disabling it in the bios, but then my laptop won't boot.
Bit of a newbie so any help would be very very much appreciated. Thanks a lot in advance.
