I've got a Dell XPS 13' (9350), with a Dell USB-C to HDMI adapter, connected to a screen. I'm running NixOS with XMonad. The screen (set to HDMI input) shows "no input signal" despite:
xrandrshowing the screen as "connected", with expected resolution (
- kernel version
4.4.8should support Skylake processor (
i915as being loaded (
lsmod | grep i915)
- screenshots show the second screen, including windows
I don't think the second screen shows up in
lshw, but then how can
xrandr see it? I'm not sure where to look next. I hope anyone here does.
EDIT: I just found out that a VGA cable connected to the same adapter does work.
