There are also Linux Console Private CSI Sequences documented in man 4 console_codes that include: ESC [ 9 ; n ] Set screen blank timeout to n minutes. ESC [ 13 ] Unblank the screen. ESC [ 14 ; n ] Set the VESA powerdown interval in minutes. So, for example, I added \e[9;16] to the beginning of /etc/issue when it became apparent that Linux wasn't blanking the console any more. I think it was buster, but could have been stretch. I wouldn't notice if bullseye still doesn't. Don't quote me on the version. Cheers, David.
