PostPosted: Wed Mar 12, 2008 7:57 pm    Post subject: Improving PS3 X resolution Reply with quote

Hello all,

I am using PS3 with a Std resolution TV. I cannot obviously expect a superb resolution but two things are quite strange:
    The image seems to be constantly shaking which is enough to hurt my eyes after a while;

    The image does not fill the TV screen completely. There's a huge (2cm) border around the whole tv screen;

My question is... are these known issues? Any way to improve them?

My X config follows:
# XFree86 4 configuration - mtb test for ps2 livecd
Section "ServerLayout"
        Identifier     "Default Layout"
        Screen  0      "Screen0" 0 0
        InputDevice    "Mouse0" "CorePointer"
        InputDevice    "Keyboard0" "CoreKeyboard"

Section "Files"
# Multiple FontPath entries are allowed (they are concatenated together)
# By default, a font server independent of the X server is
# used to render fonts.
        RgbPath      "/usr/share/X11/rgb"
        ModulePath   "/usr/lib/xorg/modules"
        FontPath     "/usr/share/X11/fonts/misc/"
        FontPath     "/usr/share/X11/fonts/TTF/"
        FontPath     "/usr/share/X11/fonts/Type1/"
        FontPath     "/usr/share/X11/fonts/75dpi/"
        FontPath     "/usr/share/X11/fonts/100dpi/"

Section "Module"
        Load  "dbe"
        Load  "extmod"
        Load  "glx"
        Load  "record"
        Load  "freetype"
        Load  "type1"
        Load  "dri"

Section "InputDevice"
# Specify which keyboard LEDs can be user-controlled (eg, with xset(1))
#       Option  "Xleds"         "1 2 3"
# To disable the XKEYBOARD extension, uncomment XkbDisable.
#       Option  "XkbDisable"
# To customise the XKB settings to suit your keyboard, modify the
# lines below (which are the defaults).  For example, for a non-U.S.
# keyboard, you will probably want to use:
#       Option  "XkbModel"      "pc102"
# If you have a US Microsoft Natural keyboard, you can use:
#       Option  "XkbModel"      "microsoft"
# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:
#       Option  "XkbLayout"     "de"
# or:
#       Option  "XkbLayout"     "de"
#       Option  "XkbVariant"    "nodeadkeys"
# If you'd like to switch the positions of your capslock and
# control keys, use:
#       Option  "XkbOptions"    "ctrl:swapcaps"
# Or if you just want both to be control, use:
#       Option  "XkbOptions"    "ctrl:nocaps"
        Identifier  "Keyboard0"
        Driver      "kbd"
        Option      "XkbModel" "pc105"
        Option      "XkbLayout" "us"

Section "InputDevice"
        Identifier  "Mouse0"
        Driver      "mouse"
        Option      "Protocol" "IMPS/2"
        Option      "Device" "/dev/input/mice"
        Option      "ZAxisMapping" "4 5"
        Option      "Emulate3Buttons" "yes"

Section "Monitor"
        Identifier   "Monitor0"
        VendorName   "Monitor Vendor"
        ModelName    "Unknown monitor"

Section "Device"
        Identifier  "Videocard0"
        Driver      "fbdev"
        Option "ShadowFB" "false"

Section "Screen"
        Identifier "Screen0"
        Device     "Videocard0"
        Monitor    "Monitor0"
        DefaultDepth 24
        DefaultFbBpp 32
        SubSection "Display"
                Viewport   0 0
                Depth     24

This is not problem of X's, this is problem of Kboot.conf.

Changing Resolution:
Edit /etc/kboot.conf using any editor and add a special parameter at the end of the kernel line:

linux="/boot/vmlinux-2.6.16 initrd=/boot/initrd.img video=ps3fb:mode:3"

Here's the full list of mode-ids
0: auto mode , default value
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

Just change the mode:X to reflect your resolution's mode-id. Reboot and it should use the new resolution settings. Give me a holler if it doesn't. I'll look for alternatives.

Basic I'am use mode:5 it's have the same border like you, i saw some topic with advice to add 128 to all mode(in my case this mean mode:133), because some kind of errors. It's help, but resolution sets to few pixsels more than FHD for my tv... I am don't try to use others mode, becouse have other problems and haven't much time to solve this ^_^

[ADD] find good instruction ^_^
