USB-C external monitor detection no longer works on my Fedora 38.
At the end of July, detection was working well.
Here’s all the information:
- Laptop : Thinkpad T14s AMD Gen3
- Monitors tested:
- Connection : USB-C to DisplayPort
- Kernel :
Linux t14s 6.4.11-200.fc38.x86_64 #1 SMP PREEMPT_DYNAMIC Wed Aug 16 17:42:12 UTC 2023 x86_64 GNU/Linux

- Desktop Gnome : 44
- Display manager : Wayland, version 1.22
I have a feeling that the problem occurred after the firmware Lenovo (ThinkPad) ThinkPad X13/T14s Gen 3 AMD was installed, I have upgraded from version
These two external monitors are detected when I connect the Thinkpad via USB-C to HDMI.
Question: have you had this problem in the last 3 weeks following a firmware or kernel update?
