Okay, most of the relevant information is in the title - I got a nice deal on an old Lenovo X280, threw Debian on there with KDE. I have an HP Elite book for my work, and thus a work provided HP G2 DisplayLink dock with USBC connection.
In order for this dock to work, I had to install the displaylink drivers for "Ubuntu" from here. The drivers work as expected, and I am able to dock the X280 to my workstation, and use both external monitors. It feels pretty nice when I am just browsing/emailing/bullshitting. But when I tried to play Minecraft on it, the game feels incredibly laggy.
At first I thought this was due to an under-powered graphics card, but I did some testing with the external monitors using an HDMI cord directly to the X280, and everything feels clean and smooth when I use it in that way. The other odd glitch is that when I have the laptop docked, and I am trying to play MC, if I put MC on the external monitor = lag. But if I just drag the MC window to the laptop's screen = no lag.
I'm assuming this issue is related to the dock and/or drivers. I've looked around for some sort of workaround, but came up empty handed. So now I think the solution might be a different dock.
The dock would need to:
- support USBC connections to my HP Elitebook, preferably without new drivers needed for the HP (dumb work won't give me admin rights, but I think I could convince them to install the necessary drivers for me. I WFH, so it makes sense that I would need a setup at home.
- support USB/Lightning to my X280
- have 1+ HDMI out or 2+ Display port out
So... Does anyone have any experience with Linux (Debian preferred) compatible docks that don't introduce input delay when gaming?
ps. Sweet community you got here. I subbed, and it's DEFINITELY going to result in me buying more stuff...
