Once every 3 or 4 boot, X starts to fail. This is on a brand new Dell Inspiron 14 Plus, NixOS (22.05) was setup about a week ago. It has Intel Graphics + NVIDIA RTX 3050. I haven’t tried to configure the NVIDIA GPU so far (I mostly want to use it on the Windows dual boot). When X fails to start on boot, a nixos-rebuild switch properly restarts X. My guess is that the Intel graphics are not always detected before the attempt to start X? Maybe there is a way to delay starting X a bit?
