Ahoj,

Mate pozapinane prislusne promenne v .config jadra?

jadro jsem jadro prelozil s temito hodnotami promennych v .config:

  ------------------------
  CONFIG_FB=y
  CONFIG_DUMMY_CONSOLE=y
  CONFIG_FB_VESA=y
  CONFIG_VIDEO_SELECT=y
  CONFIG_FBCON_ADVANCED=y
  CONFIG_FBCON_MFB=y
  CONFIG_FBCON_CFB2=y
  CONFIG_FBCON_CFB4=y
  CONFIG_FBCON_CFB8=y
  CONFIG_FBCON_CFB16=y
  CONFIG_FBCON_CFB24=y
  CONFIG_FBCON_CFB32=y
  CONFIG_FBCON_FONTS=y
  CONFIG_FONT_8x8=y
  CONFIG_FONT_8x16=y
  ------------------------

a v dokumentaci k jadru jsem nasel tuto tabulku modu

  (/Documentation/fb/vesafb.txt)

      | 640x480  800x600  1024x768 1280x1024
  ----+-------------------------------------
  256 |  0x301    0x303    0x305    0x307
  32k |  0x310    0x313    0x316    0x319
  64k |  0x311    0x314    0x317    0x31A
  16M |  0x312    0x315    0x318    0x31B

a na radku kernelu ve svem grub.conf jsem pripsat toto:

  ---------------------------------------
  vga=0x307 video=vesa:redraw,mtrr,pmipal
  ---------------------------------------

a funguje mi to dobre.
