Change the VGA mode of the Kubuntu KDE4 Remix Beta Alternative Install CD

I've just been installing the new Kubuntu KDE4 Remix Beta on an old Acer L100 Media Centre using the Alternative Install CD (so I can do a text mode install) as I only have an old CRT TV attached to it. When I tried to boot from the CD it looked like the installer picked a display mode that didn't work with the TV as the picture lost stability and was unviewable. I couldn't find the usual options to change the screen mode, but found that this worked to override the screen mode:

  • At the menu for installation press F6
  • You will now see a long line of text that tells the Linux kernel on the CD how to boot
  • Delete "quiet - -" from the end of the line
  • Enter vga=789 to force boot into 800x600 mode
  • Press enter to boo, the screen will blank for a few seconds, after that you will see the text installer 

You can find a listing of the Linux VGA modes at: http://en.wikipedia.org/wiki/VESA_BIOS_Extensions#Linux_video_mode_numbers
