# Problem: Blank Screen After Bootloader

Symptom: The screen turns black after selecting the boot menu entry.

Resolution:

1. At the GRUB2 or systemd-boot menu, press e to edit the kernel command line.
2. Append nomodeset or i915.modeset=0 or nouveau.modeset=0 before booting with Ctrl+x.
3. This forces the generic EFI framebuffer until proper display drivers initialize.
