Voodoo 3 2000 framebuffer problem

Voodoo 3 2000 framebuffer problem

[DervishD]

    Hi all :)

    Linux Kernel 2.4.29, in a do-it-yourself linux box, equipped with
an AGP Voodoo 3 2000 card, tdfx framebuffer support. I boot in vga
mode 0x0f05, with parameter 'video=tdfx:800x600-32@100' and I get
(correctly) 100x37 character grid. All of that is correct. What is
not correct is the characters attributes, namely the 'blink'
attribute.

    If I use the tdfx framebuffer (I've tested some more
resolutions), I lose the blinking text (which I use, for example, for
marking my dangling symlinks in 'ls' or 'zsh'). Is this a bug, a
feature or just a mistake I'm consistently making?

    In addition to this, at boot time the background in the lines
around the cute penguin logo is white and not black as it should...

    Thanks a lot in advance. Feel free to ask for more details,
tests, etc.

It happens too using the voodoo3 framebuffer driver in 2.6 kernels.
Specifically i'm using 2.6.10

    Nice :) I've tested under Debian unstable too, and the same
happens (using 2.6.9, IIRC). Thanks for testing :)

Blinking a whole screen of text is much more expensive than a block cursor.
You'll want hardware support, e.g. some kind of double-buffering or using
240 colors just for that purpose in a 256 color mode.
(I would not implement that.)

    I don't want to blink a whole screen of text... But I think I
know what you mean, for blinking some text on the screen you need to
be able to blink the entire screen.

    I assumed that the textmodes of framebuffer supported all
capabilities that the standard text modes support... So, no blinking
text in framebuffer, am I wrong?
