HowTo: Fullscreen on a 1080p HDTV
I am sure that if you own a 1080p HDTV you have noticed the black borders around the edges of your desktop. You may have tried the fullscreen mode via the ps3videomode command and then experienced a desktop that was a little too large for your screen. Well ... this is a guide that will enable you to use 100% of your real estate effectively.
I picked up the tip from this website.
http://www.edepot.com/playstation3.html
First, you will have to make sure that your TV settings are setup correctly. You will have to enable the "full overscan" mode on your TV for the PS3 input. You can find this option on the TV's setup menus. (the option was Settings>Screen>Display Area>Full Pixel on my Sony HDTV)
Now for the fun part ... editing some config files. First we need to edit the /etc/kboot file so that it will use fullscreen mode.
| Code: | $ sudo cp /etc/kboot.conf /etc/kboot.conf.backup
$ sudo nano /etc/kboot.conf |
You should see something like this. Change the video mode to 133. (it most likely is currently set as 5 if you have a 1080p TV) You can just erase the whole file and cut and paste this in there if you want.
| Code: | default=ubuntu
timeout=10
root=/dev/sda3
ubuntu="/boot/vmlinux initrd=/boot/initrd.img video=ps3fb:mode:133" |
Save and Exit.
Now we will have to edit our /etc/X11/xorg.conf file. We need to take out the optioonal resolutions so that the resolution will only be governed by the kboot.conf
| Code: | $ sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.backup
$ sudo nano /etc/X11/xorg.conf |
Scroll down to the "Screen" section and find the "Display" subsection that corresponds to the depth of 24 and delete the "Modes" line.
The "Screen" section should now look like this ... (if you used the original xorg.conf from the tutorial ... if you didn't, I will assume that you can figue this out)
| Code: | Section "Screen"
Identifier "Default Screen"
Device "Generic Video Card"
Monitor "Generic Monitor"
DefaultDepth 24
DefaultFbBpp 32
SubSection "Display"
Depth 24
FbBpp 32
EndSubSection
SubSection "Display"
Depth 15
Modes "1024x720" "1024x768" "800x600" "640x480"
EndSubSection
SubSection "Display"
Depth 16
Modes "576x384" "1024x768" "800x600" "640x480"
EndSubSection
EndSection
|
Now we can reboot just to see if it will all come together automagically.
Enjoy the extra large desktop!
EDIT: added the backup commands |

|

Using videomode ID 0 (automode) gave me a screen on my 1080p/HDMI TV. But I don't know which mode it wound up in. How can I query/report the actual video mode in use?

I think that you can just use
to show what mode you are in but I did not get a chance to test that so it may not be correct. |

Videomode 133 (5 + 128) in /etc/kboot.conf stretched my display past both horiz and vert boundaries of my 1080p/HDMI TV (Samsung HLS5087W). I didn't find any TV setting for underscan or anything similar. Videomode 5 gets me (apparently) 1080p resolution, but underscanned by about an inch across the display. If I have full resolution (and no runtime scaling delays), then that's just fine.
The /etc/X11/xorg.conf settings in the Ciego/PSUbuntu.com OS installation HowTo worked without needing revisions (which would be just commenting out the 'Viewport 0 0' and 'Modes "1024x720" "1124x644"' lines). B
I also set the TV to "videogame" mode, which supposedly makes the TV do more FPS.
I wish someone (Ciego  would post a HowTo on enabling the PS3 joysticks/gamepads, so I could play some games (perverse). Which Ubuntu games are good on this platform?

With /etc/kboot.conf videomode set to 0 (automode) on my 1080p/HDMI TV:
Which is YUV/60Hz/480p .
But I'd like a way to test the actual resolution, especially in mode 5 and +128 fullscreen (if I can get my TV to stop overscanning).
I guess I could open the GIMP or something, but a programmatic test would be good.
And I'd like to try mode 13, WUXGA, 1920x1200, if possible over HDMI without possibly damaging my TV input.

If you have a 1080p TV, there should be some option that is similar to "overscan" or "full pixel" on there somewere. My Sony 1080p set calls it "full pixel" for reference. Your manufacturer may call it something else but it should be there ... just check all the menus.

I got my six-axis working with some emulators but there were a few problems so I have not created a HowTo guide yet. I recently purchased a few new games so I have actually been using the PS3 for gaming lately instead of messing around with Linux. I will put it next on my list for HowTos though (I also have one coming for bluetooth when I get a little more time to mess with it.) |

My Samsung HLS5087W has a "menu map" that shows all user-accessible settings names at once (like a web sitemap), and none of them control overscan, pixel mapping or anything like that. It does have a "videogame" mode that supposedly increases the refresh FPS and black contrast, but that's not it. In the S-Video input mode I use for cable, it offers 4:3, 16:9 and Zoom1 and Zoom2 modes - the zoom modes are 16:9 zoomed in at two depths. In HDMI with the PS3, it offers only 4:3, 16:9 and "Wide Fit", which overscans so much that the desktop is at least a dozen or two pixels offscreen (no desktop menu or taskbar visible). Otherwise, in HDMI 16:9 there's about an inch above/below/besides the desktop viewport.
System... Preferences... Screen Resolution has only the value 1388x964 in its menu. A HDMI test pattern that looks perfectly gridded on my 1600x1200 noteboox LCD has curvy artifacts on the PS3 16:9 screen, perhaps because it's scaled to that 1388x964 resolution.
Is there some connection to the lack of any 1900x1200 resolution in the /etc/X11/xorg.conf file, either in the PS3/Ubuntu installation HowTo, or the update that starts off this "Fullscreen 1080P" HowTo?

| You can change your xorg.conf to use any resolution that you want really but for the PS3, the ps3videomode overides the xorg.conf I believe. |

Did you try "PC Mode" on your TV? According to the user manual, you can change it to PC mode by going to Menu>Picture>Mode>PCMode.
That might do it for you ...not sure though. |

Nevermind .... the manual later states that you cannot use PC mode through a DVI or HDMI connection. |

I installed all OK, with Kubuntu Desktop, but when I try to start kdm, I get scrambled image (actually I cannot see much on TV, I see 5 times the login, with vertical lines, unreadable).
I tried all possibble hints, resolutions from the forum, but still no luck.
My TV is an LG 26LC2R and Playstation3.
If anyone have a guide how can I succeed, I want to have the Linux on computer, but I stucked since 2 days now.
Edit/Delete Message
LATER EDIT:
I resolved the problem 90% by copying from URL
http://louiscandell.com/ps3/files/xorg.conf the content into my one. Actually I made backup and replace.
My only problem now is that the screen is too large with around 50 pixel in each part and I cannot resize it. Now I do not see the menu bars ... |

| wil this work with a 1080i TV as opposed to a 1080p as described in the how to? I have qa sony bravia which supports 1080i. I have tried the editing of the conf files with other distributions i ahve installed (ydl and gentoo) but still have either overscan or underscan. |

This will actually work for any resolution as long as your TV has the option that you can change .... mine was called "full pixel mode" |

Overscan on Samsung DLP TVs is a feature that is only accessible through the super-secret "Service Menu". Basically, you power down your TV, then press: Mute, 1, 8, 2, then power. The TV will boot up saying "Factory Loading". You can screw up all sorts of important stuff through that menu, so be careful and don't say I didn't warn you.
This thread: http://www.avsforum.com/avs-vb/showthread.php?t=697413 contains links to a bunch of useful stuff that can be done with Samsung xx87w DLP TVs. You can find what menus to look at for the overscan function in there.
Cheers. |

Thanks for that valuable info.
Any idea how to use the USB port supposedly only for inserting a Flash drive for pix/audio, to also control (and config) the TV instead of relying on IR remote emulation?
