After this happens, a key press is enough to = wake the keyboard up again. In these conditions, I am not able to reconnect the keyboard, I see the bluetooth subsystem trying to connect, but it keeps disconnecting immediately, without even a chance of typing a single char. Whenever this happens, I see the following in the kernel logs: [ 1004.980840] Lockdown: systemd-logind: hibernation is restricted; see man kernel_lockdown.7 [ 1009.107227] evdi: [I] (card0) Connector state: connected [ 1009.107297] evdi: [I] (card0) Edid property set Matter of fact, the only way I have to restore normal functionality is to p= air the keyboard again, like it was connected for the first time. The issue appears in all the following cases: - I don't use the keyboard for a few minutes (going to power-save mode) - I do a keyboard power cycle - I reboot the PC Looking at existing issues, this seems similar to the following: https://bugzilla.kernel.org/show_bug.cgi?id=3D204765 That however has been resolved a couple of years back. I use this keyboard on a Windows PC as well, and there I don't have any iss= ues (so it should not be a keyboard problem). Please let me know if you need additional debug information.
