Hi all,
I know there is a framebuffer in n810 fb0.
But I want to know the 'value' which counterpartes to the N810 current revolution.
"such as:
command: hwinfo --framebuffer
we get:
Memory Size: 5 MB
Memory Range: 0xf0000000-0xf04fffff (rw)
Mode 0x0320: 320x200 (+320), 8 bits
Mode 0x0321: 320x400 (+320), 8 bits
Mode 0x0322: 640x400 (+640), 8 bits
...
"
But in N810 , when we use the command:
hwinfo --framebuffer
we get noting we want.
What we should do?
Any help for appreciate.

Another question is that, where is the file which's funtion is like the file named "/boot/grub/menu.lst".
Because we wanna to add the vga=0x'value'
to the file.
Can you get my idea? if that , give me some suggestions.
thanx in advance.

Hi,
I wanna to port my program to N810, and it is ok on Debian.
My program can play kinds of audio/video file.
We know that a A/V file is made by vedio data and audio data.What's more,the vedio data branch is simulated to display by framebuffer and the audio data is puted to alsa in my program.
I wanna to introduce my way how to play the a/v file on debian.
1. hwinfo --framebuffer
Mode 0x0328: 1280x1024 (+1280), 8 bits
Mode 0x0329: 320x200 (+640), 16 bits
Mode 0x032a: 320x400 (+640), 16 bits
Mode 0x032b: 640x400 (+1280), 16 bits
Mode 0x032c: 640x480 (+1280), 16 bits
Mode 0x032d: 800x600 (+1600), 16 bits
Mode 0x032e: 1024x768 (+2048), 16 bits
Mode 0x032f: 1152x864 (+2304), 16 bits
Mode 0x0330: 1280x960 (+2560), 16 bits
Mode 0x0331: 1280x1024 (+2560), 16 bits
Mode 0x0332: 320x200 (+1280), 32 bits
Mode 0x0333: 320x400 (+1280), 32 bits
Mode 0x0334: 640x400 (+2560), 32 bits
this value related the current resolution.
2. configure the framebuffer
you can refer to this linker.
http://www.hyvv.org/article.asp?id=37



Likewisely, this time I wanna to port it on N810.
My idea is the same as it on Debian.
But something goes wrong, some files and folders do not exsit on n810,which you can find on Debian.
Fistly, I want to know if my idea is ok, if not , what is the right way to port on n810; if that, what i shold do to configure the framebuffer on n810 and get the value related the resolution by command "hwinfo --framebuffer" or else.

On maemo everything runs at 800*480 (barring YUV overlay apps like liqbase and mplayer).
You know the baseline and its been static for a long time now.
Only recently has the rotation support patch been added which throws up a bump in the defaults.
Why might I ask are you starting at the framebuffer itself and not using some library like XV or SDL?
I'm interested because I would love to remove a layer from liqbase but when I looked the framebuffer did not support all modes in planar format as I was anticipating.
