just wanted to reach out to those of you using a USB-C dongle and a recent kernel (6.12 and later ideally), to ask if you are also facing the issue I described here:
I can reproduce this on my FW16 (7840 without dGPU), also running the latest Tumbleweed. Kernel is 6.12.9-1-default
Once I unplug power from the Dell WD19DCS, the system tries to switch to the internal display only, but freezes. Upon replugging, it pulls 80W from the docking station but remains frozen. Haven’t tested accessing with SSH, should I?
It also happens when I just disconnect the USB connection at the notebook. This is new, must have been introduced sometime in the last week or two.
Now running a zypper dup, new kernel version 6.12.10 incoming…
Right, would also freeze with that one. Well, not completely, but the mouse cursor would move a little every couple seconds. SSH into the machine still works.
Man, these are the situations where I wished I jumped on the immutable train…I’d checkout a previous system image/commit, rebasing of overlays would be done transparently and I wouldn’t need to worry about losing any of the system packages I might have installed meanwhile.
Snapper failed me this time (but that’s on me, as I don’t have enough history to revert).
I also had something similar start happening to me. I have a pair of lenovo monitors with usb-c and dp inputs (and dp out). I have the dp in on one attached to the dp out on the other, and the dp in on the primary connected to my desktop, with the usb-c connected to my amd framework 13. I then connected a usb km switch to one of the usb-a ports on the primary monitor and the desktop so I could share the kb and mouse.
This has worked for almost a year, where I flip the usb switch and change the monitor input selection to switch between the computers. But now when I switch to the desktop, the monitors and keyboard done reconnect when I switch back, and even the built in keyboard and trackpad don’t work. I have to hold the power switch until it resets.
This could be due to a relatively recent system update, or the bios update that was recently installed.
