*bump* Question is still standing :)
I know that it's probably not possible using the standard VESA framebuffer but maybe there is a patch out there or maybe it's possible using another framebuffer driver ...?

I did not found anything about it. It looks like we both are the only people on earth with 1280x800 and framebuffer.  |

From the FrameBuffer HowTo ( http://www.tldp.org/HOWTO/Framebuffer-HOWTO.html:

| Code: |
Colours 640x400 640x480 800x600 1024x768 1152x864 1280x1024 1600x1200
--------+--------------------------------------------------------------
4 bits | ? ? 0x302 ? ? ? ?
8 bits | 0x300 0x301 0x303 0x305 0x161 0x307 0x31C
15 bits | ? 0x310 0x313 0x316 0x162 0x319 0x31D
16 bits | ? 0x311 0x314 0x317 0x163 0x31A 0x31E
24 bits | ? 0x312 0x315 0x318 ? 0x31B 0x31F
32 bits | ? ? ? ? 0x164 ?
|
Key: 8 bits = 256 colours, 15 bits = 32,768 colours, 16 bits = 65,536 colours, 24 bits = 16.8 million colours, 32 bits - same as 24 bits, but the extra 8 bits can be used for other things, and fits perfectly with a 32 bit PCI/VLB/EISA bus.
Additional modes are at the discretion of the manufacturer, as the VESA 2.0 document only defines modes up to 0x31F. You may need to do some fiddling around to find these extra modes.
|
I assume if you want it bad enough you could start throwing Hex values in there and if you manage to actually get a working mode report it.
I might have to do this when I'm bored one day myself. |
