[Linux-fbdev-devel] Make "software" cursor xterm-like

[Christian L. <chr...@fr...>]

I would like to submit the following patches to linux-2.5.7-dj1 so that:

* The "software" cursor (activate using "echo -e '\033[?17c') works like in
   "xterm":
   it merely inverses the current (color) attributes of the current underlying
   character instead of having a fixed color
   This changes affects hardware text mode and graphics framebuffers

* Blank char attributes are set equal to current char attributes
   (so that the new software cursor displays properly)

* Text blinking attribute is disabled while in hardware EGA/VGA color textmode
   so that all 16 background colors are available
   --> echo -e '\033[5m' activates "bright background"

Examples:

$ echo -e '\033[17c'
$ echo -e '\033[32;44;1m'

The text is bright green over blue
The cursor is blue over bright green

$ echo -e '\033[m\033[30;43;5m'

The text is black over yellow
The cursor is yellow over black


I would suggest that similar changes are made for the framebuffer's "hardware"
cursor so that it has "xterm -bc"-like behavior.
