Does you laptop offer a HDMI or DP connector? Have you tried if that that works any better? If it does not, then the DRM developers might be willing to look into this.
There are only USB-C port on this machine. However the external monitor still works if I use a small (passive?) HDMI-to-USB-C adapter instead of the dock.
Yeah, you had mentioned that.
Anyway: could you try to bisect the problem as described in https://docs.kernel.org/admin-guide/verify-bugs-and-bisect-regressions.html
Will do.
Thank you for your reply!
np, but stupid me forgot something (sorry): I had opened your dmesg file, but not looked into it. :-/
I see that it contains a warning from nouveau that might be hinting at the problem. Then I'd say: go and file a ticket here: https://gitlab.freedesktop.org/drm/nouveau/-/issues
Please afterwards drop a link to the ticket here please.
But a bisection might still be needed; if you do not get a reply from a developer withing two or three days, you definitely want to perform one.
