My /etc/inittab has lines that look like this:

  1:2345:respawn:/sbin/getty 38400 tty1 -I '^[c^[[?17;55;248c'

This gives me a nice red non-blinking cursor. No problems with vi
whatsoever. Of course, this only works on the console, but for my
terminal windows, I can set these values in resource or configuration
files. So, all of this is a user-space problem. No need to complicate
the kernel code.

[PATCH] bsd-style cursor

[Lennert Buytenhek]

Hi,

included a patch against 2.4.0-test9 (should apply against latest but
haven't checked) which adds the config option to have a bsd-style cursor
in VT's by default. I was hoping it might be considered for inclusion so
that I don't have to patch it in myself every time :-)


cheers,
Lennert

How about placing  

   echo '\033[?17;120c'  

In one of your startup scripts. This will give you this nice BSD cursor
you like.

[buytenh@mara buytenh]$ tail -1 ~/.bash_profile
echo -e -n '\033[?17;127c'
[buytenh@mara buytenh]$

This has Issues though: try entering vi for example.

I'd just like a way of altering CUR_DEFAULT (which is hardcoded here and
there); sysctl would be fine too for that matter.
