Can't wake laptop after systemctl suspend (USB-C dock)

gameboy56h · 2025-04-26 18:47:43

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.

Did it ever work for your @gameboy56h? I have recently installed Arch from Windows on my P1 Gen 7 but I was surprised I can't wake up the laptop by plugging in my thunderbolt dock.

Do you even all experience the same symptoms?
Does the system respond to the hardware event (LEDs, fans, …) but the resume fails (no display, no ICMP response,…) or does it not respond to the xhci/tb events at all but waking by other means (lid, power button, scheduled w/ rtcwake, …) works fine?
