    Hello,
    I have sucessfuly installed ubuntu 7.10 on my PS3 console,
    WOOOO!!!!!

    I'm using regular av jacks, So I can not view explorer windows properly.

    Long story short, Is there a way to change the ubuntu screen resolution so it can be view properly on a standard tv?

    In order to change your resolution you need to edit the /etc/kboot.conf file. So from a terminal type:
    Code:
    sudo cp /etc/kboot.conf /etc/kboot.conf.backup
    Code:
    sudo gedit /etc/kboot.conf
    Then look for a line similar to this one:
    Code:
    linux='/boot/vmlinux initrd=/boot/initrd.img root=UUID=091f3ccc-e048-4553-ba38-f4cdf4d1e789 quiet splash'
    (DO NOT COPY THIS LINE OR YOU WILL BE LEFT WITH AN UNBOOTABLE SYSTEM)

    And to the end of the line add:
    Code:
    video=ps3fb:modeX
    X being one of the values from the table below:

    Code:
    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
    So now the linux line should look like this:
    Code:
    linux='/boot/vmlinux initrd=/boot/initrd.img root=UUID=091f3ccc-e048-4553-ba38-f4cdf4d1e789 video=ps3fb:mode:X quiet splash'
    (DO NOT COPY THIS LINE OR YOU WILL BE LEFT WITH AN UNBOOTABLE SYSTEM)

    Then save the changes you made, restart your PS3 and enjoy the optimized resolution

    I followed that same guide for my 1080i tv, although it looked better if i set the resolution to 720p instead of 1080i. When i picked 1080i, the edges got cutoff.

    Just a heads up.
