I have a Lenovo ThinkPad USB-C Dock Gen 2 docking station with a DIY framework laptop. The two displays connected are a 4K (3840x2160) monitor via a DisplayPort cable and a 1920x1200 via DVI-to-DP adapter. I’ve had this setup run well before, but on a different Lenovo docking station with a different laptop (ThinkPad T14 Gen1 AMD).
I see that this particular docking station has been “vetted” in the dock megathread (USB-C/Thunderbolt Dock Megathread), but only for Windows 10. I’m currently running Manjaro i3 (but using Qtile as the actual window manager).
I can get either the 4K + eDP, or 1920x1200 + eDP working, but not all three or just the 4K + 1920x1200 monitor. The error message I get from
xrandr: Configure crtc N failed
N is some number between 0 and 2. There are bunch of attempted fixes for this error message online, but I haven’t be successful with any of them. This includes:
- Attempting with different refresh rates
- Turning on/off one monitor at a time
- Attempting with different resolutions
Anyone else run into this?
