Framebuffer Color

Chris|MD · 2006-04-06 20:25:24

I found this tutorial by phraktur here.
Well i tried it, copied that to my .bashrc but it doesnt work.
Well when i login i see all colorcodes, one after another when i comment the clear command.
Like "P0222222P8222222P18032329982b2b...".
Nothing happens then. The colors are the default ones when i use ls --color=always. The Prompt has default green i set as prompt.
echo $TERM says linux, as it should be.

So whats wrong?
I use the default vesafb with 16 million colors (vga=792). Unpatched Kernel (no Bootsplash and such things).
I only have the ifloop which sets the colors, some aliases and a prompt in my .bashrc.

What do i need to get this working? Or whats my fault?

Oh an a second question. Is it possible to get more than 60Hz with a fx 5900?
The dev of vesafg-tng says its only possible by patching the bios. Is that true? Is there really no way to get the fb to use more than 60Hz?
And if not, is it possible to patch the bios of my card without much knowledge? there are no upgrades for my card available (MSI sux i have to admit) which solve this problem.

Make sure you have "echo -ne" - the e is important (the n just makes it so your screen doesn't fill up with lines).

Um, why do you need more that 60Hz on a framebuffer device. It isn't redrawn the same way, and shouldn't be affected by a refresh rate at all. If you just want higher than 60 Hz because it's a bigger number, that's dumb. Keep it at 60 - flat panels aren't supposed to handle anything that's not 60 anyway (if you have one)

Try changing

echo -en "e]P0222222" #black

to

echo -en "e]P0222222" #black

Its not a TFT panel. Yes youre right, they only get redrawn if something changes. But i think that this is only true for those TFT panels.
But i use a CRT and it flickers@60Hz. Even if the screen is not redrawn, the monitor redraws the screen. The light doesnt stick @ the glass
Maybe youre right but i dont know how a Framebuffer differs from a default X session.
But i get a headache if i use it too long.

I copied it from your blog. So i hope its exactly how you got it in your own .bashrc.

@ibrahim

I will try that.

Yeah ibrahim's solution works.

Thanks, wordpress stripped the leading , and I didn't notice it.
