Comment 26 for bug 869017

Here's the change that was made: https://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/zesty/commit/?id=a87ae50beda8c46c543b39e19070549cf355eb65

It's just the default of the consoleblank= kernel parameter. You can override it by specifying that parameter to the kernel at boot time (eg. via /etc/default/grub)

If someone could test and document exact steps to do this override in this bug please, that'd be useful to users and I'd appreciate it.
