Odroid-C1 (and likely others): fixing the textmode cursor on the physical console

Posted by jpluimers on 2018/02/05

Somehow the Odroid C1+ does not support a blinking hardware text cursor. Which means that when you logon to the console in text mode, it is really hard to edit the command-line or text files a there is no visual clue where the cursor is.

It took me to find out the cause, but odroid C1 console no “hardware cursor” got me there: [Archive.isArch Linux ARM • View topic – ODROID-C1: No hardware cursor in terminal. The odd thing is that sending escape sequences like mentioned in [WayBackCursor Appearance in the Linux Console LG #137 didn’t fix the problem either. For instance, these didn’t help at all:

echo -n -e '\e[?17;14;224c'
echo -e "\e[?16;0;64c"

I tried similar ones from [WayBackVGA-softcursor.txt as well, but they failed too.

Since I usually ssh into the box, doing without a console cursor usually is no problem except when you run into network trouble and really need the console.

Fixing it took a bit longer to find out,  but refining to  “odroid C1” console no blinking cursor got this as first hit: [WayBackODROID Forum • View topic – fbcon cursor. And it came down to going to the second page of the first archived link above. So I had a kind of “duh” moment. Anyway, at [WayBackArch Linux ARM • View topic – ODROID-C1: No hardware cursor in terminal – pagee 2 is the below code which got me a nice large light-blue cursor:

infocmp >> ~/terminfo.txt
sed -i.bak -e 's/?0c/?112c/g' -e 's/?8c/?48;0;64c/g' terminfo.txt
tic terminfo.txt
tput cnorm

These are the commands used:
