ps3videomode: switch video mode dynamically

This command shows current video settings such as resolution, frame rate, color space, and so on, and switches them dynamically.

usage:

ps3videomode [options]

options:

--help,  -h         print this message
--video, -v <ID>    set video mode ID
--full,  -f         use full screen mode
--dither,-d         use dither ON mode

Video mode ID:
  0:automode
  YUV 60Hz  1:480i  2:480p  3:720p  4:1080i  5:1080p
  YUV 50Hz  6:576i  7:576p  8:720p  9:1080i 10:1080p
  RGB 60Hz 33:480i 34:480p 35:720p 36:1080i 37:1080p
  RGB 50Hz 38:576i 39:576p 40:720p 41:1080i 42:1080p
  VESA     11:WXGA 12:SXGA 13:WUXGA

  full screen mode: <video mode ID> + 128
  dither ON mode  : <video mode ID> + 2048

If no arguments are given, ps3videomode displays the current video mode.

example:

ps3videomode -v 3 -f (720p 60Hz with full screen mode.)

ps3videomode -v 131 (Same as above.)

note:

VESA resolutions are only valid for HDMI port.
The signal from HDMI port supports RGB color space regardless of video mode ID.
Don’t change the display resolution while sound is playing.
Don’t change the display resolution on X-Window. If you did, you need to restart the Xserver, because of current ps3fb driver doesn't use fixed size frame buffer. It is needed that 'line_length' of frame buffer is used as fixed value to realize changing resolution via X.
If you want to boot linux as specified video mode, you may use kernel parameter. It has been described on other section about How to Use Kboot.

boot-game-os: shutdown linux and switch to game os

This command switches boot flag in “other-os flash area” to boot game os, and reboot onto game os. This command requires root privilege.

usage:

boot-game-os

other-os-flash-util: other-os flash area manipulation utility

other-os-flash-util [-b|-B] [-g|-r] flash_device [boot_loader_img]
other-os-flash-util -s flash_device
other-os-flash-util -d flash_device

options:

-s show current settings
-d print difference of clock time between game os and linux
-b change boot flag : boot game os
-B change boot flag : boot linux
-g change boot loader format flag : compressed by gzip
-r change boot loader format flag : not compressed

find-other-os-flash: find out other-os flash
