I need help troubleshooting a display.
I need help troubleshooting a display.
I'm running Garuda. My laptop screen is on its very last legs. I have an external monitor that connects via USB-C. It has a Display Port connection, but the laptop itself does not. I'm using HDMI to connect to a larger display, but not having two monitors available is driving me insane. I know that the firmware supports display over USB-C, since it has worked before on previous distros and on Windows. My issue is that I can't get the system to recognize the display, and I'm not sure where to start troubleshooting.
I can post whatever dumps etc. if asked, but here's a neofetch screenshot screenshot for starters:
Are there packages I need to install? Drivers? I'm clueless and would really appreciate a starting point at the least. The last thing I need is a broken system because I'd have to use the (almost) entirely broken laptop screen to attempt a reinstall/change the BIOS.
I think the issue is due to the fact that your laptop has a discrete Nvidia GPU, which complicates things on Linux machines. Your display outputs are therefore controlled by the Nvidia drivers themselves rather than the Linux kernel.
Check out sections 2.4.x of the Arch wiki Nvidia page and maybe you can find a way to configure it manually.
Thanks a lot! I knew this might be a rabbit hole, so thanks for the starting point!
I think you're looking for DP alt mode drivers. That's what allows DisplayLink over USB.
Awesome! Do you happen to know where/how I can grab those? ETA: Installed the DisplayLink stuff, but don't know where to go from here.
Did you also enable the required service?
