Dell Pro 14 Premium PA14250 - Hang on Boot Ubuntu

Laptop Model: Dell Pro 14 Premium (PA14250)

CPU/GPU: Intel Core Ultra 200V (Lunar Lake), Graphics ID 64a0 (Stepping B0)

OS: Ubuntu 25.10 (Kernel 6.17.0-14-generic) same with Ubuntu 24.04

Firmware: Dell BIOS 2.4.2 same with Dell BIOS 2.9

The Issue: The system boots, decrypts the LUKS partition, and completes the services load (reaches snapd.apparmor.service), but then stops there. Does not reach the login page. I tried a couple of GRUB workarounds. The system is active in the background (keyboard lights up on trackpad touch), but Ctrl+Alt+F3 does not bring up a TTY. LLM suggests that: the xe driver is hanging during the display initialization handshake. Key Logs (via journalctl -b -1):

xe 0000:00:02.0: [drm] Found lunarlake (device ID 64a0) integrated display version 20.00 stepping B0xe 0000:00:02.0: [drm] Selective fetch area calculation failed in pipe Agnome-shell[3032]: Added device '/dev/dri/card1' (xe) using atomic mode setting.wmi_bus wmi_bus-PNP0C14:02: [Firmware Bug]: WQBC data block query control method not found

What I have tried so far:

• BIOS Updates: Updated to 2.9
• GRUB Parameters: Tried combinations of xe.force_probe=64a0, xe.enable_psr=0, xe.enable_fbc=0, and video=eDP-1:e.
• Blacklisting: Blacklisted intel_vsc and intel_ish_ipc to resolve a -517 context sensing error.
• Display Server: Disabled Wayland in /etc/gdm3/custom.conf to force X11.
• Firmware: Verified lnl_guc_70.bin and lnl_huc.bin are loading successfully.

Workaround: System only boots with nomodeset, but this disables all graphics acceleration.
