Custom Desktop Resolution

[bismuthdrummer]

I did a bunch of searches, checked the Wiki, and tried modifying xorg.conf myself, to no avail. Lots of talk about wanting higher resolution, but I would like to run a desktop resolution lower than 800x480 (specifically, 720x480).

Any way this can be done on a stock image?

Why?

 

[bismuthdrummer]

Respectfully, it's a yes or no question. The reason is immaterial. For academic curiosity's sake.

A screen is not a computer monitor, it lacks the logic to stretch the input.

In other words you wont get a picture from that unless you want to display black bars on the screen.

Actually omapfb can do stretching/scaling, but I guess he wants to have the 40px black bars, because stretching 720 to 800 would introduce annoying blur.

No idea how to do it though -- most likely notaz will know.

This might help. Don't know if this can be used with X... but I can't even get it working with my project

Out of interest, why 720x480 specifically?  It seems like an odd aspect ratio to be attempting as it doesn't match any traditional screen geometry that I'm familiar with.

720 is the maximum width achievable by TV-Out. It's not the aspect ratio I'm attempting so much as simply limiting the width. But the concept extends to height as well; if I have to run 720x400 or somesuch that is fine.

I do want to force a true resolution (as opposed to scaling), so if the answer is no or would take a major hack I completely understand. Thanks for the input so far.

Dr. Notaz, you have have a call on line 3, Dr. Notaz line 3.

Not really on topic, but I think live info would fit in that bar.

Gentle bump.


Anything I can do?

Without checking on my Pandora, I assume it defines its X resolution in /etc/xorg.conf.  Have you looked in there to see what sort of controls it offers?  There's a lot on the internet about that.

I played with this a little bit, but it almost seems that X ignores modes set in the xorg.conf. I know resolution in these embedded devices are often defined in the boot arguments, without my pandora I can't really confirm that is how it's done though.

On the BeagleBoard RevC3 ist the Resolution defined in the Boot.scr.


Raik gave me a Boot.scr for 800x600 Resolution.


We can run the Pandora Zaxxon on Beagleboard but no Sound and no PND Support for now.


Omap3530.


I tried to change the Resolution on the Pandora but it always ended with a black Screen and a Full Reflash with the right MLO and Bootfiles.

Anything I can do?

In /etc/init.d/psplash change

fbset -depth 16

to

fbset -depth 16 -g 720 480 720 480 16

As always, you're the best notaz!

Will give this a shot. Thank you.

EDIT: And it work as hoped (image top-left-justified, black space on the right and bottom given a smaller x and y). Makes the TV-out much crisper and easier to adjust for me.
