L1 Displayport KVM switching inputs unexpectedly

Hardware Other Hardware
1

I’ve been using the L1 displayport kvm switch quite happily for a few months now. I have the following setup:

1 LG 32" 1440 display
1 Dell 27" 4k display

Displays are both connected with displayport 1.4 cables. I have my desktop (Ryzen 7 Machine with a 6800XT) connected to PC1 (both displays and usb). On PC2 is my work Macbook pro. I don’t have the second Dell display hooked up to the macbook, just the LG one.

Lately I’m having an issue when I’m playing a game on my desktop where after a while without any input from me the KVM will switch over to the second input. It happens even when the macbook is powered off. I haven’t had this occur any other time. I can use the desktop for non-gaming, or the laptop for work, indefinitely without any issue.

Interestingly, it seems to happen when I’m gaming on Linux, but didn’t happen in the past when I was using the same machine running windows to play games.

Any idea what might cause this, or if there’s something I can do about my setup to prevent it?

Try scroll scroll left Ctrl. Left Ctrl is a leading key like scroll lock and maybe it’s picking that up every now and then in your game confusing the KVm when really you’re just spamming left Ctrl

Now that you mention it I do press left ctrl quite a lot in this particular game so it’s very likely. I wondered why the thing beeped every so often when I was playing and now playing around with it a bit I realize it only happens when I press the left ctrl key a bunch of times. Mystery solved, I think?

Yep, scroll scroll left Ctrl will disable listening for it
