All;


I am running Fedora 35 on a LG Gram 17


Its been running great, however yesterday I upgraded the kernel
from:

   5.19.11-100.fc35.x86_64

   to:

   5.19.12-100.fc35.x86_64


Now if I boot into the latest kernel my external monitor is no
longer
reckognized, if I boot the new kernel with the external monitor
attached
I never get a login prompt but I just get a black screen



Thoughts on how to debug?
Not really, but it would probably be useful to state your video
driver
(AMD, Nvidia proprietary, Intel, Nvidia free etc.) and display server
(X11, Wayland), e.g. for me:

$ inxi -G
Graphics:
   Device-1: Intel IvyBridge GT2 [HD Graphics 4000] driver: i915 v:
kernel
   Device-2: NVIDIA GP107 [GeForce GTX 1050] driver: nvidia v:
515.65.01
   Display: x11 server: X.Org v: 1.20.14 with: Xwayland v: 22.1.3
driver: X:
     loaded: modesetting,nouveau,nvidia unloaded: fbdev,vesa gpu: i915
     resolution: 1920x1080~60Hz
   OpenGL: renderer: Mesa Intel HD Graphics 4000 (IVB GT2) v: 4.2 Mesa
     22.1.7

more you can see what was install an try rollback
