[Help] ps3/ubuntu screen resolution?

ubunix · #1 08-26-2008

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?

Hey, welcome to the club I also have Ubuntu on my PS3

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.
