Will formatting it to ext4 screw anything up? You think maybe if I used my PC to install a distro and format there would be safer than formatting on the Deck?
not sure why you need to boot into desktop mode at least once, and return to game mode from there, but the workaround fixed the problem for the user who reported the issue
Just FYI, Displaylink is basically emulates a video card over USB, USB DP alt mode is a completely different thing as is not an emulation, is a DP link directly from your iGPU
