Hi all,
I'm having a really annoying issue with suspending my system.
My laptop is connected to a USB-C docking station with an external monitor attached.
When I put the system to sleep using `systemctl suspend`, it seems to suspend just fine, but I can't wake it up afterward no matter what I do.
If no external monitors are connected to the dock, suspend works fine.
Has anyone dealt with something like this? I'd love any advice!
logs from journalctl ends on : suspend entry (s2idle)

Same issue here (the only difference being that I can wake up the laptop using the docking station if the laptop stays connected to it – but not if I disconnected the laptop and want to wake it up later in another setting). Also in my case, the system log ends with suspend (with one further line on filesystem sync).
I think the issue occurred for the first time about a week ago. I am using linux 6.14.4 (the newest version) on a Thinkpad X1 Carbon Gen 11.
