Hardware • Screen stays black on resume from suspend

Hi,

I've installed Debian Bookworm with KDE on my Thinkpad X13 AMD Gen 1. The laptop is on a 40AH docking station, screen closed when this happen. Connected on the dock there is a screen (AOC, Display Port), keyboard, mouse, webcam, scanner. I'm with the latest back ported kernel (6.7.12) because of my WiFi card (Mediatek MT7921). Firmware seems to be up-to-date, fwupdmgr didn't report something to update.

I have to do ctrl+alt+f2 and ctrl+alt+f1 to make the screen to start back. The USB seems to wake-up.

Sometimes the USB doesn't seems to wake up, but if I undock/dock the laptop, I can ear the power supply disconnect or connect KDE sound. If I open the laptop in this case, the screen stays black too. The keyboard can illuminate,n but doesn't seems responsive. So hard shutdown... Not good...

Is someone having an idea ?

Bests regards,
