ユーザーモードの問題

  • Classic graphics mode setting (User Mode-Setting) is problematic:
    • hardware is being initialized multiple times
      • first by the BIOS for its boot messages ...
      • then by the framebuffer driver for the boot console ...
      • and finally by the X Server
    • flickers during boot
    • flickers when changing between virtual consoles and X Server instances
