I already posted my issue in the community forum on the aggregated 5.10 issues thread, but I assume my post was forgotten. Thus I decided to raise this issue here so that it can be tracked properly. I apologize for the double posting!
Following last week's sync (on January 23), my laptop boots to a black screen and never reaches the greeter. I'm using both current kernel and current nvidia driver, with UEFI booth. Rebooting and switching to the previous kernel (5.10.7) with the bootloader allows me to login normally.
Below are my system specs (from running inxi -CG):
CPU: Info: Dual Core model: Intel Core i7-7500U bits: 64 type: MT MCP L2 cache: 4 MiB Speed: 3500 MHz min/max: 400/3500 MHz Core speeds (MHz): 1: 3500 2: 3500 3: 3500 4: 3500 Graphics: Device-1: Intel HD Graphics 620 driver: i915 v: kernel Device-2: NVIDIA GM107M [GeForce GTX 950M] driver: nvidia v: 460.32.03 Device-3: Realtek Integrated Camera type: USB driver: uvcvideo Display: x11 server: X.Org 1.20.10 driver: modesetting,nvidia resolution: 1920x1080~60Hz OpenGL: renderer: GeForce GTX 950M/PCIe/SSE2 v: 4.6.0 NVIDIA 460.32.03
Here is the log (obtained by running sudo journalctl -b -e > journaltcl.log) from my latest failed boot:
